Release Notes¶
v2.30.0 Latest
Apr 01, 2026✨ New Features
🔄 Reactive Model Hooks
ninja_aio/models/hooks.py,ninja_aio/models/serializers.py,ninja_aio/models/utils.py
Declarative lifecycle hooks for ModelSerializer and Serializer. Define sync or async callbacks that fire automatically on create, update, and delete operations — with optional field-level triggers for updates.
from ninja_aio.models import ModelSerializer
from ninja_aio.models.hooks import on_create, on_update, on_delete
class Article(ModelSerializer):
# ...
@on_create
async def notify_author(self):
await send_notification(self.author, "Article created")
@on_update("status")
async def handle_publish(self):
if self.status == "published":
await index_article(self)
@on_delete
def cleanup(self):
logger.info(f"Article {self.pk} deleted")
Key capabilities:
| Feature | Description |
|---|---|
@on_create |
Fires after successful create |
@on_update / @on_update("field") |
Fires after update, optionally only when specific fields change |
@on_delete |
Fires before delete |
suppress_signals |
Context manager to temporarily disable all hooks |
| Async + sync | Both supported — framework detects and dispatches correctly |
Works with both ModelSerializer and Serializer (Meta-driven) patterns.
🎨 Swagger UI Branding
ninja_aio/docs.py,ninja_aio/api.py,ninja_aio/templates/ninja_aio/branded_swagger.html
Customizable Swagger UI via a Branding dataclass. Personalize your API docs with logos, colors, and custom CSS — zero JavaScript required.

primary_color="#6C63FF",
favicon_url="/static/favicon.ico",
custom_css=".swagger-ui .topbar { display: none; }",
)
)
Template variables:
| Variable | Type | Default | Description |
|---|---|---|---|
logo_url |
str |
None |
Header logo image URL |
primary_color |
str |
None |
Accent color for buttons, links, headers |
favicon_url |
str |
None |
Browser tab favicon |
custom_css |

Additional CSS injected into the page |
Auto-activates BrandedSwagger renderer when any branding option is set. Falls back to default Swagger UI when no branding is configured.
🍪 JWT Cookie Authentication (BFF)
ninja_aio/auth.py
AsyncJwtCookie — cookie-based JWT authentication for Backend for Frontend patterns. Reads JWTs from HttpOnly cookies with built-in CSRF protection via Django Ninja's APIKeyCookie.
from ninja_aio.auth import AsyncJwtCookie
class CookieAuth(AsyncJwtCookie):
jwt_public = jwk.RSAKey.import_key(settings.JWT_PUBLIC_KEY)
param_name = "access_token" # cookie name (default)
claims = {
"iss": {"value": settings.JWT_ISSUER},
"aud": {"value": settings.JWT_AUDIENCE},
}
async def auth_handler(self, request):
return await User.objects.aget(id=self.dcd.claims["sub"])
Cookie helpers:
| Function | Description |
|---|---|
set_jwt_cookie(response, token, ...) |
Set JWT as HttpOnly cookie with secure defaults |
delete_jwt_cookie(response, ...) |
Remove JWT cookie (logout) |
secure defaults to not settings.DEBUG — automatically secure in production, works over HTTP in development.
Architecture: JwtAuthMixin extracts shared JWT logic, eliminating duplication between AsyncJwtBearer (header-based) and AsyncJwtCookie (cookie-based).
AsyncJwtBearer |
AsyncJwtCookie |
|
|---|---|---|
| Token location | Authorization: Bearer header |
HttpOnly cookie |
| Best for | SPAs, mobile, API-to-API | BFF, server-rendered apps |
| XSS protection | Token accessible to JS | Token inaccessible to JS |
| CSRF | Not needed | Built-in (enabled by default) |
🔧 Improvements
🧩 JwtAuthMixin Refactor
ninja_aio/auth.py
Extracted shared JWT decode/validate/dispatch logic into JwtAuthMixin. Both AsyncJwtBearer and AsyncJwtCookie now compose from this mixin — zero code duplication, same behavior.
🏷️ Type Hints for Hooks and Signals
ninja_aio/models/hooks.py,ninja_aio/models/utils.py
Added type annotations to all hook functions and signal handlers for improved IDE support and clarity.

v2.29.0
Mar 25, 2026✨ New Features
🗑️ Soft Delete Mixin
ninja_aio/views/mixins.py
SoftDeleteViewSetMixin replaces hard deletes with a boolean flag. Soft-deleted records are automatically excluded from list/retrieve/update. Provides restore and permanent delete endpoints.
from ninja_aio.views.mixins import SoftDeleteViewSetMixin
class ArticleAPI(SoftDeleteViewSetMixin, APIViewSet):
model = Article # must have is_deleted = BooleanField(default=False)
bulk_operations = ["create", "update", "delete"]
What changes:
| Endpoint | Without Mixin | With Mixin |
|---|---|---|
DELETE /{pk}/ |
Row removed from DB | Sets is_deleted=True |
DELETE /bulk/ |
Rows removed from DB | Sets is_deleted=True on all |
GET / (list) |
All records | Excludes is_deleted=True |
GET /{pk}/ |
Any record | 404 if is_deleted=True |
PATCH /{pk}/ |
Any record | 404 if is_deleted=True |
POST /{pk}/restore |
— | ✨ Restores soft-deleted record |
DELETE /{pk}/hard-delete |
— | ✨ Permanently removes record |
Configuration:
| Attribute | Type | Default | Description |
|---|---|---|---|
soft_delete_field |
str |
"is_deleted" |
Name of the BooleanField on the model |
include_deleted |
bool |
False |
True for admin views — soft-deleted records are visible |
Composability: Works with PermissionViewSetMixin, filter mixins, and @action endpoints. Put SoftDeleteViewSetMixin first in MRO.
Validation: Raises ImproperlyConfigured at init if the model lacks the configured field.
🔍 Multi-Field Search Mixin
ninja_aio/views/mixins.py
SearchViewSetMixin adds a ?search= query parameter that searches across multiple fields with case-insensitive substring matching (OR logic).
from ninja_aio.views.mixins import SearchViewSetMixin
class ArticleAPI(SearchViewSetMixin, APIViewSet):
model = Article
search_fields = ["title", "content", "author__name"]
search_param = "q" # default: "search"
GET /articles/?q=django
Searches title, content, and author__name simultaneously — returns any record where at least one field contains "django" (case-insensitive).
Configuration:
| Attribute | Type | Default | Description |
|---|---|---|---|
search_fields |
list[str] |
[] |
Fields to search (supports __ lookups) |
search_param |
str |
"search" |
Query parameter name |
Composability: Works with all filter mixins — search narrows first, then field-specific filters apply:
class ArticleAPI(SearchViewSetMixin, IcontainsFilterViewSetMixin, APIViewSet):
model = Article
search_fields = ["title", "content"]
query_params = {"category": (str, None)}
# GET /articles/?search=django&category=tutorial
🔧 Improvements
⚡ Performance Optimizations (8 fixes)
N+1 M2M batch query:
ninja_aio/helpers/api.py
M2M validation now resolves all PKs in a single filter(pk__in=...) query instead of per-PK queries. With 100 objects to validate: 101 queries → 2 queries.
Batch field resolution:
ninja_aio/models/utils.py
All field objects resolved in a single sync_to_async call instead of N individual thread pool switches per field. With 10 fields: 10 thread switches → 1.
COUNT query optimization:
ninja_aio/views/api.py
List view count uses .acount() directly instead of .values(pk).acount() which generated an unnecessary subquery.
Prefetch without refetch:
ninja_aio/models/utils.py
After update, reverse relations are loaded via aprefetch_related_objects() directly on the instance instead of refetching the entire object from DB. Eliminates 1 extra query per update.
Cache key optimization:
ninja_aio/models/utils.py
Relation cache keys use id() (O(1)) instead of str() (O(n)) for class references.
Cached properties:
ninja_aio/models/utils.py
pk_field_type, model_fields, model_name, model_pk_name converted from @property to @cached_property — computed once per ModelUtil instance.
No-copy cache returns:
ninja_aio/models/utils.py
Removed 4 redundant .copy() calls on cached relation lists. Cache hits now return direct references.
Direct PK extraction:
ninja_aio/views/api.py
_get_pk() uses getattr() instead of model_dump() — direct attribute access instead of full schema serialization on every retrieve/update/delete.
📊 Realistic Performance Benchmarks
tests/performance/test_performance.py
Added MultiFKPerformanceTest and LargeListPerformanceTest covering:
| Benchmark | Description |
|---|---|
create_3fk |
Create with 3 FK fields |
bulk_create_50x3fk |
50 objects × 3 FKs each |
list_1000_page20 |
List 1000 records, page size 20 |
list_1000_page100 |
List 1000 records, page size 100 |

- ⚡ N+1 → batch — M2M validation uses single batched query instead of per-PK queries
- ⚡ Fewer thread switches — field resolution batched into single sync_to_async call
- ⚡ No refetch after update — aprefetch_related_objects loads reverse relations in-place
- ⚡ O(1) cache keys — id() instead of str() for class references
- ⚡ Cached properties — static metadata computed once per ModelUtil instance

v2.28.0
Mar 23, 2026✨ New Features
🔐 Permission System with Operation Hooks
ninja_aio/views/mixins.py,ninja_aio/views/api.py,ninja_aio/exceptions.py
A three-level permission system built on overridable operation hooks. Permissions are checked at view-level (before any DB query), object-level (after fetch, before mutation), and row-level (filters list queryset).
from ninja_aio.views import APIViewSet
from ninja_aio.views.mixins import PermissionViewSetMixin
class ArticleAPI(PermissionViewSetMixin, APIViewSet):
model = Article
async def has_permission(self, request, operation):
"""View-level: deny non-staff from writing."""
if operation in ("create", "update", "delete"):
return request.auth.is_staff
return True
async def has_object_permission(self, request, operation, obj):
"""Object-level: only owners can modify."""
return obj.owner_id == request.auth.id
def get_permission_queryset(self, request, queryset):
"""Row-level: users only see their own articles."""
return queryset.filter(owner=request.auth)
PermissionViewSetMixin hooks:
| Hook | When | Raises |
|---|---|---|
🛡️ has_permission(request, operation) |
Before any DB query | ForbiddenError (403) |
🔒 has_object_permission(request, operation, obj) |
After fetch, before mutation | ForbiddenError (403) |
🔍 get_permission_queryset(request, queryset) |
Before pagination in list view | Filters rows silently |
RoleBasedPermissionMixin — declarative role mapping:
from ninja_aio.views.mixins import RoleBasedPermissionMixin
class ArticleAPI(RoleBasedPermissionMixin, APIViewSet):
model = Article
permission_roles = {
"admin": ["create", "list", "retrieve", "update", "delete"],
"editor": ["create", "list", "retrieve", "update"],
"reader": ["list", "retrieve"],
}
role_attribute = "role" # reads from request.auth.role
New exception:
from ninja_aio.exceptions import ForbiddenError
raise ForbiddenError(details="Permission denied for operation: delete")
# → 403 {"message": "forbidden", "details": "Permission denied for operation: delete"}
🏗️ Operation Hooks on APIViewSet
ninja_aio/views/api.py
Three overridable hooks executed at different stages of CRUD, bulk, and @action operations. These form the foundation of the permission system but can be used independently for logging, auditing, or custom validation.
class ArticleAPI(APIViewSet):
model = Article
async def on_before_operation(self, request, operation):
"""Called before every operation (create, list, retrieve, update, delete, bulk_*, @action)."""
logger.info(f"User {request.auth.id} performing {operation}")
async def on_before_object_operation(self, request, operation, obj):
"""Called after fetch, before mutation (retrieve, update, delete)."""
if obj.is_locked and operation in ("update", "delete"):
raise ForbiddenError(details="Object is locked")
def on_list_queryset(self, request, queryset):
"""Called after filters/ordering, before pagination."""
return queryset.filter(is_published=True)
| Hook | Applies to |
|---|---|
on_before_operation |
All CRUD + bulk + @action endpoints |
on_before_object_operation |
retrieve, update, delete (single-object endpoints) |
on_list_queryset |
list endpoint only |
🏛️ Auto Django Admin Generation
ninja_aio/admin.py,ninja_aio/models/serializers.py
Generate Django ModelAdmin classes automatically from ModelSerializer field configuration. Admin list_display, search_fields, list_filter, and readonly_fields are derived intelligently from serializer inner classes.
Option 1 — @register_admin decorator:
from ninja_aio import register_admin
from ninja_aio.models import ModelSerializer
@register_admin
class Book(ModelSerializer):
class Meta:
model = BookModel
class ReadSerializer:
fields = ["title", "author", "published_at", "is_active"]
class UpdateSerializer:
fields = ["title", "author"]
Option 2 — as_admin() class method:
from django.contrib import admin
admin.site.register(BookModel, Book.as_admin(list_per_page=50))
Option 3 — model_admin_factory() function:
from ninja_aio.admin import model_admin_factory
AdminClass = model_admin_factory(BookModel, list_per_page=50)
admin.site.register(BookModel, AdminClass)
Field classification logic:
| Field Type | list_display |
search_fields |
list_filter |
readonly_fields |
|---|---|---|---|---|
| 📝 CharField, TextField, SlugField, EmailField, URLField | ✅ | ✅ | ❌ | If not in UpdateSerializer |
| ☑️ BooleanField | ✅ | ❌ | ✅ | If not in UpdateSerializer |
| 📅 DateField, DateTimeField | ✅ | ❌ | ✅ | If not in UpdateSerializer |
| 🔗 ForeignKey, OneToOneField | ✅ | ❌ | ✅ | If not in UpdateSerializer |
| 🔀 ManyToManyField | ❌ | ❌ | ✅ | ❌ |
📋 Configurable Bulk Response Fields
ninja_aio/views/api.py,ninja_aio/models/utils.py
New bulk_response_fields attribute on APIViewSet controls what fields are returned in bulk operation success details instead of PKs only.
class ArticleAPI(APIViewSet):
model = Article
bulk_operations = ["create", "update", "delete"]
# Option 1: Single field value
bulk_response_fields = "slug"
# → {"success": {"count": 2, "details": ["my-article", "other-article"]}}
# Option 2: Multiple fields as dicts
bulk_response_fields = ["id", "slug", "title"]
# → {"success": {"count": 2, "details": [
# {"id": 1, "slug": "my-article", "title": "My Article"},
# {"id": 2, "slug": "other-article", "title": "Other Article"}
# ]}}
# Option 3: Default (None) — PK only (backward compatible)
bulk_response_fields = None
# → {"success": {"count": 2, "details": [1, 2]}}
Works with all three bulk operations. For bulk_delete, field values are fetched before deletion.
✅ Require Update Fields Validation
ninja_aio/views/api.py,ninja_aio/models/utils.py
New require_update_fields attribute rejects empty PATCH requests (all-None payloads).
class ArticleAPI(APIViewSet):
model = Article
require_update_fields = True
# PATCH /articles/1 {} → 400 {"message": "No fields provided for update."}
# PATCH /articles/1 {"title": "New"} → 200 OK
Also applies to bulk update operations.
🔧 Improvements
⚡ List View Returns QuerySet Directly — Native CursorPagination Support
ninja_aio/views/api.py,ninja_aio/helpers/api.py
list_view and M2M get_related now return the QuerySet directly to @paginate instead of serializing all objects first via list_read_s. This means:
- ✅
CursorPaginationworks natively — receives a real QuerySet for.order_by()and.filter() - ⚡ Only the current page is fetched from DB — pagination slices at the database level
- ⚡ Only page_size objects are serialized — Django Ninja handles serialization after pagination
from ninja.pagination import CursorPagination
class ArticleAPI(APIViewSet):
model = Article
pagination_class = CursorPagination # ← just works now
Performance with 17k records: list_view time is constant regardless of total dataset size (ratio 17k/1k ≈ 1.0x).
🔢 403 Error Code Added to ERROR_CODES
ninja_aio/views/api.py
ERROR_CODES extended from {400, 401, 404} to {400, 401, 403, 404}. All endpoints now advertise 403 Forbidden responses in OpenAPI schema.
🏷️ Comprehensive Type Annotations
ninja_aio/views/api.py
Explicit return type annotations added to all APIViewSet public methods and properties:
| Method | Return Type |
|---|---|
add_views_to_route() |
None |
get_schemas() |
tuple[Schema \| None, ...] |
create_view(), list_view(), etc. |
Callable |
_crud_views, _bulk_views |
dict[str, tuple[Schema \| None, Callable]] |
query_params_handler() |
QuerySet |

v2.27.0
Mar 18, 2026✨ New Features
⚡ @action Decorator for Custom ViewSet Endpoints
ninja_aio/decorators/actions.py,ninja_aio/views/api.py
Add custom endpoints to any APIViewSet using the @action decorator. Actions support detail (single instance) and list (collection) modes, multiple HTTP methods, auth inheritance, custom decorators, and full OpenAPI metadata.
from ninja import Schema, Status
from ninja_aio.decorators import action
class CountSchema(Schema):
count: int
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
# Detail action: operates on a single instance
@action(detail=True, methods=["post"], url_path="activate")
async def activate(self, request, pk):
obj = await self.model_util.get_object(request, pk)
obj.is_active = True
await obj.asave()
return Status(200, {"message": "activated"})
# List action: operates on the collection
@action(detail=False, methods=["get"], url_path="count", response=CountSchema)
async def count(self, request):
total = await self.model.objects.acount()
return {"count": total}
Key features:
| Feature | Description |
|---|---|
🎯 detail=True |
Auto-adds {pk} to URL, renamed to match model PK field |
🔗 url_path |
Auto-generated from method name (_ → -) if not provided |
| 🔐 Auth inheritance | auth=NOT_SET inherits from viewset per-verb auth |
🛡️ Survives disable=["all"] |
Actions are always registered, even when CRUD is disabled |
| 🔄 Multiple methods | methods=["get", "post"] creates separate routes |
| 🎨 Decorators | decorators=[aatomic] applies custom wrappers |
📦 Bulk Operations (Create, Update, Delete)
ninja_aio/models/utils.py,ninja_aio/views/api.py,ninja_aio/schemas/api.py
Opt-in bulk endpoints for creating, updating, or deleting multiple objects in a single request with partial success semantics.
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
bulk_operations = ["create", "update", "delete"]
Generated endpoints:
| Method | Path | Description |
|---|---|---|
POST |
/{base}/bulk/ |
Bulk create |
PATCH |
/{base}/bulk/ |
Bulk update |
DELETE |
/{base}/bulk/ |
Bulk delete |
Response format — BulkResultSchema:
{
"success": { "count": 2, "details": [1, 3] },
"errors": { "count": 1, "details": [{"error": "Not found."}] }
}
Design decisions:
- ✅ Partial success — each item is processed independently; failures don't affect other items
- ✅ PKs only —
success.detailsreturns primary keys, not serialized objects - ✅ Optimized bulk delete — single
DELETE ... WHERE pk IN (...)query - ✅ Per-item hooks —
parse_input_data(),custom_actions(),post_create()called per item - ✅ Per-verb auth —
post_authfor create,patch_authfor update,delete_authfor delete
New schemas:
| Schema | Description |
|---|---|
BulkDetailSchema |
{count: int, details: list} |
BulkResultSchema |
{success: BulkDetailSchema, errors: BulkDetailSchema} |
Refactored ModelUtil methods:
| Method | Description |
|---|---|
_create_instance() |
Extracted from create_s() — creates object + runs hooks, returns model instance |
_update_instance() |
Extracted from update_s() — updates object + runs hooks, returns model instance |
bulk_create_s() |
Creates multiple objects, returns (created_pks, error_details) |
bulk_update_s() |
Updates multiple objects, returns (updated_pks, error_details) |
bulk_delete_s() |
Deletes multiple objects (single query), returns (deleted_pks, error_details) |
_format_bulk_error() |
Static helper for error formatting |
🔀 Native Ordering / Sorting
ninja_aio/views/api.py
Add native ordering to the list endpoint with two new APIViewSet attributes:
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
ordering_fields = ["created_at", "title", "views"]
default_ordering = "-created_at"
How it works:
- 📌 Automatically adds an
orderingquery parameter to the filters schema - ✅ Validates each field against
ordering_fields(invalid fields silently ignored) - 🔄 Supports ascending (
field), descending (-field), and multi-field (-views,title) - 📦
default_orderingaccepts a string or list; applied when no valid?orderingis provided - 🛡️
orderingis popped from filters beforequery_params_handlerruns — no interference with filter mixins - ⚡ Completely disabled when
ordering_fieldsis empty (default)
New APIViewSet attributes:
| Attribute | Type | Default | Description |
|---|---|---|---|
ordering_fields |
list[str] |
[] |
Fields allowed for ordering |
default_ordering |
str \| list[str] |
[] |
Default ordering when no ?ordering param |
🔧 Improvements
🏷️ disable Attribute Extended for Bulk Operations
ninja_aio/views/api.py,ninja_aio/types.py
The disable attribute now supports bulk operation values:
| Value | Description |
|---|---|
bulk_create |
Disable bulk create endpoint |
bulk_update |
Disable bulk update endpoint |
bulk_delete |
Disable bulk delete endpoint |
🎨 DecoratorsSchema Extended for Bulk Operations
ninja_aio/schemas/helpers.py
Three new fields added to DecoratorsSchema:
| Field | Description |
|---|---|
bulk_create |
Decorators for bulk create endpoint |
bulk_update |
Decorators for bulk update endpoint |
bulk_delete |
Decorators for bulk delete endpoint |
🚀 Batch Queryset Serialization — Up to 94% Faster
ninja_aio/models/utils.py
Queryset serialization has been fundamentally optimized. Previously, each object in a queryset was serialized via an individual sync_to_async(schema.from_orm)(obj) call, creating N event loop context switches for N objects. Now, the entire queryset is serialized in a single sync_to_async call via the new _bump_queryset_from_schema() method.
Before (per-object):
# N sync_to_async calls — one per object
[await self._bump_object_from_schema(obj, schema) async for obj in instance]
After (batched):
# 1 sync_to_async call — entire queryset serialized at once
async def _bump_queryset_from_schema(self, queryset, schema):
def _serialize_all():
return [schema.from_orm(obj).model_dump() for obj in queryset]
return await sync_to_async(_serialize_all)()
Benchmark results:
| Metric | Before | After | Improvement |
|---|---|---|---|
| ⏱️ Bulk serialization (500 objects) | 21.80ms | 1.35ms | -93.8% |
| ⏱️ Bulk serialization (100 objects) | 6.03ms | 0.49ms | -92.0% |
| ⏱️ List endpoint (100 records) | 5.14ms | 0.82ms | -84.0% |
🔄 sync_to_async overhead |
4975% | 102% | ~50x reduction |
| 📊 Per-object overhead | 0.119ms | 0.001ms | 119x less |
Scalability at 17k records:
| Metric | Before | After |
|---|---|---|
⏱️ list_read_s (17k records) |
1.217s | 0.077s |
| 📊 Throughput | ~0.07ms/obj | ~0.005ms/obj |
Both _read_s() and _serialize_queryset() now use _bump_queryset_from_schema() for list serialization. Single-object serialization via _bump_object_from_schema() remains unchanged.
🔗 Set-Based M2M Membership Validation
ninja_aio/helpers/api.py
M2M add/remove validation now uses a set of PKs instead of a list of full model instances for membership checks.
Before:
# O(n) list — loads all related objects with select_related
rel_objs = [rel_obj async for rel_obj in related_manager.select_related().all()]
# O(n) membership check per PK
if remove ^ (rel_obj in rel_objs):

# O(n) set — loads only PKs, no select_related overhead
rel_obj_pks = {rel_obj.pk async for rel_obj in related_manager.all()}
# O(1) membership check per PK
if remove ^ (rel_obj.pk in rel_obj_pks):
Two optimizations combined:
- 🔍 O(1) membership checks — set lookup instead of list scan
- 📦 No select_related() — only PKs are needed, not full related objects

🎯 Summary
Version 2.27.0 introduces three major features — @action decorator, bulk operations, and native ordering — alongside a major performance optimization that makes serialization up to 94% faster for large datasets.
Key benefits:
- ⚡ @action decorator — add custom endpoints with auth inheritance, detail/list distinction, and auto URL generation
- 📦 Bulk operations — create, update, and delete multiple objects in a single request with optimized bulk delete
- 🔀 Native ordering — two-attribute configuration (ordering_fields, default_ordering) replaces manual query_params_handler ordering logic
- 🚀 Up to 94% faster serialization — batch sync_to_async eliminates per-object overhead; 17k records in 0.077s (down from 1.2s)
- 🔗 O(1) M2M validation — set-based PK membership checks replace O(n) list scans
- 🧩 Composable — all features work seamlessly with existing filter mixins, pagination, and decorators

🏷️ NinjaAIOMeta Inner Class for Model-Level Framework Configuration
ninja_aio/types.py,ninja_aio/exceptions.py,ninja_aio/models/utils.py,ninja_aio/models/serializers.py,ninja_aio/views/api.py
Models can now declare a NinjaAIOMeta inner class for framework-specific configuration that Django's Meta class cannot handle. All attributes are optional.
class Article(models.Model):
title = models.CharField(max_length=255)
class NinjaAIOMeta:
not_found_name = "article" # custom 404 error key
verbose_name = "Blog Article" # override for API display
verbose_name_plural = "Blog Articles" # override for routes & display
Resolution priority (3-tier):
| Priority | Source | Example |
|---|---|---|
| 1️⃣ Highest | ViewSet class attribute | model_verbose_name = "Article" |
| 2️⃣ Middle | NinjaAIOMeta inner class |
NinjaAIOMeta.verbose_name = "Blog Article" |
| 3️⃣ Lowest | Django Meta |
Meta.verbose_name = "article" |
New helper function:
from ninja_aio.types import get_ninja_aio_meta_attr
# Returns attribute from NinjaAIOMeta, or default if not found
name = get_ninja_aio_meta_attr(MyModel, "not_found_name")
name = get_ninja_aio_meta_attr(MyModel, "verbose_name", default="fallback")
New ModelUtil property:
| Property | Description |
|---|---|
model_verbose_name |
🏷️ Returns model verbose name (NinjaAIOMeta → Django Meta fallback) |
📦 Status Object Returns for All View Endpoints
ninja_aio/views/api.py,ninja_aio/helpers/api.py
All CRUD and M2M view endpoints now return Django Ninja Status objects instead of raw tuples or data. This provides explicit HTTP status codes with typed response data.
CRUD views:
| Endpoint | Return |
|---|---|
create |
Status(201, data) |
list |
Status(200, data) |
retrieve |
Status(200, data) |
update |
Status(200, data) |
delete |
Status(204, data) |
M2M views:
| Endpoint | Return |
|---|---|
get_related |
Status(200, data) |
manage_related |
Status(200, M2MSchemaOut(...)) |

🐛 Fix NotFoundError with model._meta Custom Attributes
ninja_aio/exceptions.py
The previous not_found_name feature checked model._meta.not_found_name, but Django's Options class silently ignores custom attributes on Meta. This was effectively dead code. Now uses NinjaAIOMeta.not_found_name via the get_ninja_aio_meta_attr() helper.

🎯 Summary
Version 2.26.0 introduces NinjaAIOMeta for model-level framework configuration and migrates all view returns to Django Ninja Status objects for explicit HTTP status code handling. The release also fixes the broken not_found_name feature and widens dependency constraints.
Key benefits:
- 🏷️ Model-level configuration — NinjaAIOMeta inner class for not_found_name, verbose_name, and verbose_name_plural
- 📦 Explicit status codes — All views return Status(code, data) instead of raw tuples
- 🐛 Bug fix — not_found_name now works correctly via NinjaAIOMeta (was dead code via model._meta)
- 🔧 Wider compatibility — Support for Django Ninja <1.7.0 and joserfc <1.5.0

📦 LRU-Bounded Relation Cache
ninja_aio/models/utils.py
The class-level _relation_cache on ModelUtil has been replaced with a bounded LRU cache (maxsize=512). In long-running processes, the previous unbounded dict could grow indefinitely; the new cache evicts least-recently-used entries when the limit is reached.
class LRUCache:
"""Thread-safe LRU cache backed by OrderedDict."""
def __init__(self, maxsize: int = 512): ...
def get(self, key): ... # Returns None on miss, promotes on hit
def set(self, key, value): ... # Evicts LRU entry when full
def clear(self): ...
Behavior:
- get() promotes entries to most-recent position (LRU semantics)
- set() evicts the oldest entry when maxsize is exceeded, logging the eviction at DEBUG level
- Cache key format unchanged: (model, serializer_class_str, is_for)
🔧 Improvements
🔁 Refactored Match Case Filter Application
ninja_aio/views/mixins.py
The MatchCaseFilterViewSetMixin.query_params_handler method has been refactored: the inline filter application logic was extracted into a dedicated _apply_case_filter(queryset, case_filter) method. This improves readability and testability without changing behavior.
| Before | After |
|---|---|
20-line inline if/else block with nested isinstance checks |
Single _apply_case_filter() call per match case |
🐛 Fix NotFoundError Constructor
ninja_aio/exceptions.py
Fixed incorrect return super().__init__(...) in NotFoundError.__init__ when a custom not_found_name is set. The return keyword prevented the constructor from completing properly. Now calls super().__init__(...) followed by an explicit return.

v2.24.0
Mar 09, 2026✨ New Features
🔗 Instance Binding on Serializer
ninja_aio/models/serializers.py
Serializer now supports instance binding: a model instance can be attached to a serializer at construction time or via attribute assignment, eliminating the need to pass it on every method call.
Constructor:
serializer = ArticleSerializer(instance=article)
Attribute assignment (after construction):
serializer = ArticleSerializer()
serializer.instance = article
Instance-bound usage:
serializer = ArticleSerializer(instance=article)
await serializer.update({"title": "Breaking news"}) # uses bound instance
await serializer.save() # uses bound instance
data = await serializer.model_dump() # uses bound instance
changed = serializer.has_changed("title") # uses bound instance
changed = await serializer.ahas_changed("title") # uses bound instance
Explicit method arguments always take priority over self.instance. Calling an instance-dependent method when neither is set raises a clear ValueError.
🔧 Improvements
📐 Optional instance on save, update, model_dump, has_changed, ahas_changed
ninja_aio/models/serializers.py
All instance-dependent methods now accept instance as an optional parameter that falls back to self.instance:
| Method | Old signature | New signature |
|---|---|---|
save |
save(instance) |
save(instance=None) |
update |
update(instance, payload) |
update(payload, instance=None) |
model_dump |
model_dump(instance, schema=None) |
model_dump(instance=None, schema=None) |
has_changed |
has_changed(instance, field) |
has_changed(field, instance=None) |
ahas_changed |
ahas_changed(instance, field) |
ahas_changed(field, instance=None) |
!!! warning "Breaking: parameter order changed for update, has_changed, ahas_changed"
payload/field moved to first position and instance became the optional trailing arg.
🛡️ _resolve_instance helper
ninja_aio/models/serializers.py
Internal _resolve_instance(instance) method centralizes instance resolution logic: prefers the explicit argument, falls back to self.instance, and raises ValueError with a descriptive message when neither is available.
📖 Documentation
docs/api/models/serializers.md— added Instance Binding section; updated all method signatures and code examples to the new parameter order; addedsaveandupdateexamples; added migration warning admonitions.docs/tutorial/serializer.md— added Instance Binding tutorial section covering constructor binding, attribute assignment, instance replacement, priority rules, and error behaviour; updated learning objectives and checklist.
🎯 Summary
Version 2.24.0 introduces instance binding to Serializer, a quality-of-life feature for workflows that operate on the same model instance across multiple calls.
Key benefits:
- 🔗 Less repetition — bind the instance once, omit it from every subsequent call
- 🔄 Flexible — bind at construction or assign via serializer.instance = obj at any time
- ⚡ Priority rule — explicit method arguments always win, enabling ad-hoc overrides without rebinding
- 🛡️ Clear errors — descriptive ValueError when no instance is available
- ✅ Fully backwards-compatible for save and model_dump — existing positional calls continue to work

📦 Widened orjson Dependency Constraint
pyproject.toml
The orjson version constraint has been relaxed from <= 3.11.5 to < 4.0.0, allowing any stable 3.x release to satisfy the dependency. This removes the tight upper pin and lets projects use newer patch and minor releases of orjson as they are published, without waiting for a constraint update in this package.
| Dependency | Before | After |
|---|---|---|
orjson |
>= 3.10.7, <= 3.11.5 |
>= 3.10.7, < 4.0.0 |
🎯 Summary
Version 2.23.1 is a maintenance release that loosens the orjson upper bound to track the full 3.x release line.
Key benefits:
- 📦 Fewer conflicts — projects can upgrade orjson freely within the 3.x series
- 🔒 Still safe — the < 4.0.0 bound guards against potentially breaking 4.x changes

🐍 NotFoundError Class-Name Key Uses snake_case
ninja_aio/exceptions.py
When NINJA_AIO_NOT_FOUND_ERROR_USE_VERBOSE_NAMES = False, the error key produced by NotFoundError is now automatically converted from CamelCase to snake_case (all lowercase), instead of using the raw Python class name.
Before (v2.22.0):
# settings.py
NINJA_AIO_NOT_FOUND_ERROR_USE_VERBOSE_NAMES = False
raise NotFoundError(BlogPost)
# {"BlogPost": "not found"} ← raw class name
After (v2.23.0):
raise NotFoundError(BlogPost)
# {"blog_post": "not found"} ← snake_case
raise NotFoundError(TestModelSerializer)
# {"test_model_serializer": "not found"}
This ensures the error key is consistent with standard JSON conventions and matches the format already used by the default verbose_name mode.
Implementation:
| File | Change |
|---|---|
ninja_aio/exceptions.py |
model.__name__ converted via re.sub(r"(?<!^)(?=[A-Z])", "_", name).lower() |

🎯 Summary
Version 2.23.0 refines the use_verbose_name=False behaviour introduced in 2.22.0. The error key is now always snake_case, making it consistent with both the default verbose-name format and standard JSON naming conventions.
Key benefits:
- 🐍 Consistent casing — both modes now produce snake_case error keys
- ✅ Backwards-compatible — only affects the use_verbose_name=False opt-in mode

🔧 Configurable NotFoundError Key Format
ninja_aio/exceptions.py
NotFoundError now supports a configurable error key format via the Django setting NINJA_AIO_NOT_FOUND_ERROR_USE_VERBOSE_NAMES.
By default (True), the error key continues to use the model's verbose_name with spaces replaced by underscores — preserving full backwards compatibility.
When set to False, the error key uses the Python model class name (model.__name__) instead, which is useful when verbose names contain spaces that are undesirable in JSON keys or when a more Pythonic identifier is preferred.
Default behaviour (unchanged):
# Model with verbose_name = "blog post"
raise NotFoundError(BlogPost)
# {"blog_post": "not found"}
Class name mode:
# settings.py
NINJA_AIO_NOT_FOUND_ERROR_USE_VERBOSE_NAMES = False
raise NotFoundError(BlogPost)
# {"BlogPost": "not found"}
Setting reference:
| Setting | Type | Default | Description |
|---|---|---|---|

🎯 Summary
Version 2.22.0 adds fine-grained control over how NotFoundError formats its JSON error key. The new NINJA_AIO_NOT_FOUND_ERROR_USE_VERBOSE_NAMES setting is fully backwards-compatible — existing projects are unaffected unless they opt in.
Key benefits:
- 🔧 Configurable — choose between verbose_name (default) or __name__ as the not-found error key
- ✅ Backwards-compatible — default behaviour is identical to v2.21.0
- 📚 Documented — new dedicated Exceptions API reference page

🔒 Generic Type System for Full Type Safety
ninja_aio/models/utils.py,ninja_aio/models/serializers.py,ninja_aio/views/api.py,ninja_aio/views/mixins.py,ninja_aio/api.py
The entire framework is now fully generic, providing complete IDE autocomplete and static type checking for all CRUD operations. When you specify model type parameters, type checkers (mypy, pyright, pylance) understand exactly which model types are being used.
Generic Serializer[ModelT] — Type-safe CRUD methods:
from ninja_aio.models.serializers import Serializer, SchemaModelConfig
from myapp.models import Book
class BookSerializer(Serializer[Book]): # 👈 Specify model type
class Meta:
model = Book
schema_in = SchemaModelConfig(fields=["title", "author"])
schema_out = SchemaModelConfig(fields=["id", "title", "author"])
# All methods are now properly typed!
serializer = BookSerializer()
book: Book = await serializer.create({"title": "1984"}) # ✅ Returns Book
book: Book = await serializer.save(book) # ✅ Accepts/returns Book
data: dict = await serializer.model_dump(book) # ✅ Accepts Book
Generic APIViewSet[ModelT] — Type-safe model_util access:
from ninja_aio.views import APIViewSet
from ninja_aio.api import NinjaAIO
api = NinjaAIO()
@api.viewset(Book)
class BookAPI(APIViewSet[Book]): # 👈 Explicitly typed
async def my_method(self, request):
# self.model_util is typed as ModelUtil[Book]
book: Book = await self.model_util.get_object(request, pk=1)
print(book.title) # ✅ IDE autocomplete works!
Generic ModelUtil[ModelT] — Automatic type inference:
from ninja_aio.models.utils import ModelUtil
# Type automatically inferred as ModelUtil[Book]
util = ModelUtil(Book)
book: Book = await util.get_object(request, pk=1) # ✅ Returns Book
books: QuerySet[Book] = await util.get_objects(request) # ✅ Returns QuerySet[Book]
Generic Mixins — All filter mixins are now generic:
from ninja_aio.views.mixins import IcontainsFilterViewSetMixin
@api.viewset(Author)
class AuthorAPI(IcontainsFilterViewSetMixin[Author]): # 👈 Specify type
query_params = {"name": (str, None)}
async def custom_method(self, request):
author: Author = await self.model_util.get_object(request, pk=1)
print(author.name) # ✅ Autocomplete works!
Key benefits:
- ✅ IDE Autocomplete — Your IDE suggests correct model fields and methods
- ✅ Type Checking — Type checkers catch errors at development time
- ✅ Better Refactoring — Renaming fields or changing types is caught automatically
- ✅ Zero Runtime Overhead — Generic types are erased at runtime
Implementation details:
| File | Changes |
|---|---|
ninja_aio/models/utils.py |

ViewSetT = TypeVar("ViewSetT", bound=APIViewSet) # api.py only
Updated docstrings:
All generic classes now include comprehensive type safety examples in their docstrings showing:
- How to specify type parameters
- Expected return types for all methods
- IDE autocomplete behavior
- Type inference patterns
🔍 Field Change Detection Method
ninja_aio/models/serializers.py
Added has_changed(instance, field) method to Serializer class for detecting if a model field has changed compared to its persisted database value.
@api.viewset(Article)
class ArticleViewSet(APIViewSet):
serializer_class = ArticleSerializer
async def custom_update(self, request, pk: int, data):
article = await Article.objects.aget(pk=pk)
article.title = data.title
# Check if title changed before sending notification
if self.serializer.has_changed(article, "title"):
await send_notification(f"Title updated: {article.title}")
await article.asave()
return await self.serializer.model_dump(article)
Use cases:
- 🔔 Conditional notifications (only notify if a specific field changed)
- 📝 Audit logging (track which fields were modified)
- ✅ Validation (enforce business rules based on field changes)
- 🗄️ Caching (invalidate cache only when relevant fields change)
Behavior:
- Returns True if in-memory value differs from DB value
- Returns False for new instances (those without a primary key)
- Performs a targeted query: .filter(pk=pk).values(field).get()[field]
📤 Custom Schema Parameter for Serialization Methods
ninja_aio/models/serializers.py
Both model_dump() and models_dump() now accept an optional schema parameter, allowing you to specify a custom schema for serialization instead of using the default (detail or read schema).
model_dump(instance, schema=None) — Serialize single instance:
# Use default schema (detail schema if defined, otherwise read schema)
data = await serializer.model_dump(article)
# Use a specific custom schema
custom_schema = ArticleSerializer.generate_read_s()
data = await serializer.model_dump(article, schema=custom_schema)
models_dump(instances, schema=None) — Serialize multiple instances:
# Use default schema
articles = Article.objects.all()
data = await serializer.models_dump(articles)
# Use a specific custom schema
custom_schema = ArticleSerializer.generate_read_s()
data = await serializer.models_dump(articles, schema=custom_schema)
New internal method:
| Method | Description |
|---|---|
_get_dump_schema(schema=None) |
🎯 Returns provided schema, or falls back to detail schema → read schema |
Use cases:
- 🎨 Different response formats for the same endpoint

🏠 README Updates
README.md
Added Type Safety as the first feature in the features table:
| Feature | Technology | Description |
|---|---|---|
| 🔒 Type Safety | Generic classes | Full IDE autocomplete and type checking with generic ModelUtil, Serializer, and APIViewSet |
🎯 Summary
Version 2.20.0 introduces comprehensive type safety across the entire framework through generic classes, bringing django-ninja-aio-crud on par with modern Python frameworks in terms of static type analysis support.
Key benefits:
- 🎯 Zero Breaking Changes — All existing code continues to work without modification
- 🔒 Type Safety — Full IDE autocomplete and type checking when you specify type parameters
- 📚 Documentation — Comprehensive guide covering all type safety patterns
- 🛠️ Enhanced Serializers — Field change detection and flexible schema dumping
- ⚡ Zero Runtime Cost — Generic types are erased at runtime, no performance impact
Three typing approaches:
1. Type the Serializer (Recommended) — Type once, all serializer methods typed
2. Type the ViewSet — For model_util-heavy code
3. Type both — Maximum type safety everywhere
The framework now provides the same level of type safety as Django Stubs, FastAPI, and SQLAlchemy 2.0 while maintaining its async-first design and zero-boilerplate philosophy.
v2.19.0
Feb 04, 2026✨ New Features
🔧 Schema Method Overrides on Serializer Inner Classes
ninja_aio/models/serializers.py
You can now define Pydantic schema method overrides (e.g., model_dump, model_validate, custom properties) on serializer inner classes. The framework automatically injects these methods into the generated Pydantic schema subclass, with full super() support via __class__ cell rebinding.
ModelSerializer — define on inner serializer classes:
from __future__ import annotations
from typing import TYPE_CHECKING, Any
if TYPE_CHECKING:
from ninja import Schema
class MyModel(ModelSerializer):
name = models.CharField(max_length=255)
class ReadSerializer:
fields = ["id", "name"]
def model_dump(
self: Schema,
*,
mode: str = "python",
include: Any = None,
exclude: Any = None,
context: Any = None,
by_alias: bool = False,
exclude_unset: bool = False,
exclude_defaults: bool = False,
exclude_none: bool = False,
round_trip: bool = False,
warnings: bool | str = True,
serialize_as_any: bool = False,
) -> dict[str, Any]:
data = super().model_dump(
mode=mode, include=include, exclude=exclude,
context=context, by_alias=by_alias,
exclude_unset=exclude_unset, exclude_defaults=exclude_defaults,
exclude_none=exclude_none, round_trip=round_trip,
warnings=warnings, serialize_as_any=serialize_as_any,
)
data["name"] = data["name"].upper()
return data
Serializer (Meta-driven) — define on validator inner classes:
class MySerializer(serializers.Serializer):
class Meta:
model = MyModel
schema_out = serializers.SchemaModelConfig(fields=["id", "name"])
class ReadValidators:
def model_dump(self: Schema, **kwargs) -> dict[str, Any]:
data = super().model_dump(**kwargs)
data["name"] = data["name"].upper()
return data
New core methods on BaseSerializer:
| Method | Description |
|---|---|
_collect_schema_overrides(source_class) |
🔍 Scans a class for regular callables that aren't validators, config attrs, or dunders |
_get_schema_overrides(schema_type) |
🗺️ Maps schema types to their override source class (overridden per serializer) |
Implementation details:
- Overrides are collected alongside validators during schema generation
- __class__ cell rebinding via types.FunctionType + types.CellType ensures bare super() resolves to the correct subclass
- Validators, model_config, and method overrides coexist on the same inner class
- _CONFIG_ATTRS frozenset filters out configuration attributes (fields, customs, optionals, excludes, relations_as_id, model_config)
⚙️ Pydantic model_config Support on Serializers
ninja_aio/models/serializers.py
Both serializer patterns now support applying Pydantic ConfigDict to generated schemas.
ModelSerializer — via model_config attribute:
from pydantic import ConfigDict
class MyModel(ModelSerializer):
name = models.CharField(max_length=255)
class CreateSerializer:
fields = ["name"]
model_config = ConfigDict(str_strip_whitespace=True)
Serializer (Meta-driven) — via model_config_override in SchemaModelConfig:
class MySerializer(serializers.Serializer):
class Meta:
model = MyModel
schema_in = serializers.SchemaModelConfig(
fields=["name"],
model_config_override=ConfigDict(str_strip_whitespace=True),
)
New core methods on BaseSerializer:
| Method | Description |
|---|---|
_get_model_config(schema_type) |
Returns ConfigDict for the given schema type |
New field on SchemaModelConfig:
| Field | Type | Description |
|---|---|---|
model_config_override |
Optional[dict] |
Pydantic ConfigDict to apply to the generated schema |

🎯 Summary
Django Ninja AIO v2.19.0 introduces two major serializer features: schema method overrides and Pydantic model_config support. Schema method overrides let you inject custom methods (like model_dump) into generated Pydantic schemas from inner serializer classes, with full super() support via __class__ cell rebinding. Pydantic ConfigDict can now be applied per-schema for configuration like str_strip_whitespace. This release also adds a framework comparison benchmark suite and statistical performance analysis tools.
Key benefits:
- 🔧 Schema Method Overrides — Inject custom model_dump, model_validate, or any method into generated schemas with bare super() support
- ⚙️ Pydantic ConfigDict — Apply model_config per-schema on both ModelSerializer and Meta-driven Serializer
- 🔬 Framework Comparison — Benchmark against Django Ninja, ADRF, and FastAPI with interactive HTML reports
- 📊 Regression Detection — Statistical tools for detecting performance regressions in CI/CD
- 📱 Mobile-Fixed Charts — Chart.js charts render correctly on mobile viewports
- 🧪 23 New Tests — Comprehensive coverage for overrides, model_config, and edge cases
- 🔄 Backward Compatible — All changes are additive with no breaking changes
v2.18.3
Feb 02, 2026⚡ Performance Improvements
🚀 Foreign Key Resolution Optimization
ninja_aio/models/utils.py
Eliminated redundant database queries during create and update operations by optimizing how foreign key relationships are loaded after object persistence.
The Problem:
When creating or updating objects with foreign key fields, the framework was fetching FK relationships twice:
1. Once in _resolve_fk() to convert FK IDs to model instances (required by Django's ORM)
2. Again in get_object() with select_related when retrieving the created/updated object
Example of redundancy:
# User creates: POST {"name": "Article", "author_id": 5}
# Before optimization:
# Query 1: SELECT * FROM author WHERE id = 5 (_resolve_fk)
# Query 2: INSERT INTO article (name, author_id) VALUES (...)
# Query 3: SELECT * FROM article
# LEFT JOIN author ON ...
# WHERE id = 123 (get_object - redundant!)
# After optimization:
# Query 1: SELECT * FROM author WHERE id = 5 (_resolve_fk)
# Query 2: INSERT INTO article (name, author_id) VALUES (...)
# Query 3: SELECT * FROM article WHERE id = 123 (prefetch reverse relations only)
# # FK already in memory, not re-fetched!
New method:
| Method | Line | Description |
|---|---|---|
_prefetch_reverse_relations_on_instance() |
645-689 | Prefetches only reverse relations (reverse FK, reverse O2O, M2M) on an existing instance without re-fetching forward FKs |
How it works:
- No reverse relations → Returns original instance with FK cache intact
- Reverse relations exist → Refetches instance with:
-prefetch_related()for reverse relations
-select_related()for forward FKs to keep them loaded
Modified methods:
| Method | Line | Change |
|---|---|---|
create_s() |
883-899 | Now keeps full object from acreate() instead of just PK; calls _prefetch_reverse_relations_on_instance() instead of get_object() |
update_s() |
1085-1100 | Calls _prefetch_reverse_relations_on_instance() instead of second get_object() after save |
_resolve_fk() |
632-634 | Added None check for nullable FK fields |
Performance impact:
| Operation | Before | After | Queries Saved |
|---|---|---|---|
| Create (with FK, no reverse rels) | FK fetch → Create → Full refetch (FK + reverse) | FK fetch → Create → Return (FK in memory) | 1 FK query ✅ |
| Create (with FK + reverse rels) | FK fetch → Create → Full refetch (FK + reverse) | FK fetch → Create → Refetch (FK + reverse) | 1 FK query ✅ |
| Update (changing FK, no reverse rels) | Full fetch → New FK fetch → Update → Full refetch | Full fetch → New FK fetch → Update → Return (FK in memory) | 1 FK query ✅ |
| Update (changing FK + reverse rels) | Full fetch → New FK fetch → Update → Full refetch | Full fetch → New FK fetch → Update → Refetch (FK + reverse) | 1 FK query ✅ |
Real-world example:
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
pass
# POST /articles/
# Payload: {"title": "Django Ninja", "author_id": 5}
#
# Before: 3 queries (2 for author FK - redundant!)
# After: 2 queries (1 for author FK)
#
# Result: 33% fewer queries for create operations with FKs!
Edge case handling:
| Scenario | Behavior |
|---|---|
Nullable FK with None value |
Skips FK resolution (line 632-634) |
| Model with FK but no reverse relations | Returns original instance, no refetch needed |
| Model with FK and reverse relations | Refetches with both select_related and prefetch_related |
| Model without FK fields | No change in behavior |

Test results:
- ✅ 617 tests pass (up from 608)
- ✅ 19 performance tests pass
- ✅ 99% coverage on ninja_aio/models/utils.py (line 686 is defensive code for models with both forward FKs and reverse relations - not exercised by current test suite but important for real-world usage)
🎯 Summary
Django Ninja Aio CRUD v2.18.3 is a performance optimization release that eliminates redundant foreign key queries during create and update operations. By intelligently caching FK instances resolved during input parsing and only refetching reverse relations when necessary, the framework reduces database queries by 33% for typical CRUD operations involving foreign keys. This optimization is completely transparent to end users - no code changes required - while delivering measurable performance improvements for API endpoints with relational data.
Key benefits:
- ⚡ 33% Fewer Queries — One less DB query per create/update operation with foreign keys
- 🎯 Smart Caching — Forward FKs kept in memory after resolution, only reverse relations refetched when needed
- 🔒 Zero Breaking Changes — Completely backward compatible, optimization happens automatically
- 🧪 Thoroughly Tested — 9 new tests covering all FK scenarios and edge cases
- 📊 Performance Benchmarks — All 19 performance tests pass with no regressions
- 💡 Transparent — No code changes needed to benefit from optimization
v2.18.2
Feb 02, 2026🔧 Improvements
✨ Removed Redundant Input Validation
ninja_aio/models/utils.py
Removed redundant input field validation logic since Pydantic already validates all inputs before they reach the payload processing stage. This simplifies the codebase and properly handles field aliases and custom fields.
Removed methods:
| Method | Previous Line | Why Removed |
|---|---|---|
_validate_input_fields() |
746-782 | Redundant - Pydantic validates all inputs during schema deserialization |
get_valid_input_fields() |
198-237 | Only used by removed _validate_input_fields() method |
Updated method:
- parse_input_data() - Removed call to _validate_input_fields() and added clarifying comment that Pydantic handles all validation
Why this improves the code:
Since Django Ninja uses Pydantic to validate all inputs against generated schemas:
- ✅ Custom fields (defined via custom_fields parameter) are validated by Pydantic
- ✅ Field aliases are properly handled by Pydantic during deserialization
- ✅ By the time parse_input_data() receives the Schema instance, all validation has already occurred
- ✅ model_dump() simply converts the validated instance to a dict with proper field names
The removed validation was:
- ❌ Redundant (Pydantic already validated)
- ❌ Incomplete (couldn't properly handle all Pydantic features like aliases)
- ❌ Assuming custom fields and aliases couldn't be used in requests
Example of what now works correctly:
from pydantic import Field
from ninja_aio.models import Serializer, serializers
class UserSerializer(Serializer):
class Meta:
model = User
schema_in = serializers.SchemaModelConfig(
fields=["username", "email"],
custom_fields=[
("display_name", str, Field(alias="displayName")) # Alias support
]
)
# Input with alias now works properly:
# {"username": "john", "email": "john@example.com", "displayName": "John Doe"}
# Pydantic handles the alias → Validation passes → No redundant checks
🧪 Tests
ModelUtilHelperMethodsTestCase — Removed 3 tests
Removed tests:
| Test | Reason |
|---|---|
test_validate_input_fields_valid_fields |
Method _validate_input_fields no longer exists |
test_validate_input_fields_invalid_fields |
Method _validate_input_fields no longer exists |
test_validate_input_fields_skips_custom_fields |
Method _validate_input_fields no longer exists |
Test results:
- ✅ 608 tests pass (down from 611)
- ✅ 100% coverage maintained on ninja_aio/models/utils.py
- ✅ 99% overall coverage maintained
🎯 Summary
Django Ninja Aio CRUD v2.18.2 is a code quality improvement release that removes redundant validation logic. By trusting Pydantic's built-in validation, the codebase is simplified while properly supporting all Pydantic features including field aliases and custom fields. This change has no impact on end users since Pydantic was already handling validation - we simply removed the redundant secondary validation that was incomplete and caused issues with aliases.
Key benefits:
- 🧹 Simpler Code — Removed 70+ lines of redundant validation logic
- ✅ Proper Alias Support — Field aliases now work correctly without workarounds
- 🎯 Trust the Framework — Pydantic handles all input validation; no redundant checks needed
- 🔒 Same Security — No security impact since Pydantic validation was already the primary defense
- 🧪 100% Coverage — Maintained complete test coverage across the codebase
v2.18.1
Feb 01, 2026🔒 Security Fixes
🔄 Circular Reference Protection
ninja_aio/models/serializers.py
Fixed potential infinite recursion and stack overflow from circular model relationships by adding thread-safe circular reference detection.
New methods:
| Method | Line | Description |
|---|---|---|
_resolution_context |
1921 | Thread-local storage for resolution stack |
_get_resolution_stack() |
1926-1934 | Returns resolution stack for current thread |
_is_circular_reference() |
1937-1954 | Checks if model/schema_type is already being resolved |
_push_resolution() |
1957-1962 | Pushes model/schema_type onto resolution stack |
_pop_resolution() |
1965-1969 | Pops model/schema_type from resolution stack |
Enhanced method:
- _resolve_related_model_schema() (lines 1994-2039) - Now detects circular references and raises ValueError with clear message
Example scenario that previously caused infinite recursion:
class Author(ModelSerializer):
articles = models.ManyToManyField('Article', related_name='authors')
class ReadSerializer:
fields = ['id', 'name', 'articles']
class Article(ModelSerializer):
authors = models.ManyToManyField(Author, related_name='articles')
class ReadSerializer:
fields = ['id', 'title', 'authors'] # Circular!
Now raises a clear error instead of causing stack overflow.
🛡️ Field Injection Prevention
ninja_aio/models/utils.py
Fixed potential security vulnerability by adding input field validation to prevent malicious field injection in payloads.
New methods:
| Method | Line | Description |
|---|---|---|
get_valid_input_fields() |
2282-2322 | Returns allowlist of valid field names from model |
_validate_input_fields() |
2440-2476 | Validates payload fields against model, raises ValueError for invalid fields |
Applied in:
- parse_input_data() (line 908) - Validates all input payloads before processing
Now blocks malicious payloads:
{
"username": "hacker",
"password": "secret",
"_state": {}, # ❌ Now blocked
"pk": 999, # ❌ Now blocked if not in model fields
}
🔍 Filter Field Validation
ninja_aio/views/api.py
Fixed potential filter injection vulnerability by adding comprehensive filter field validation.
New validation methods:
| Method | Line | Description |
|---|---|---|
_validate_filter_field() |
2749-2840 | Main validation method for filter field paths |
_is_lookup_suffix() |
Helper | Checks if suffix is valid Django lookup (e.g., __icontains, __gte) |
_get_related_model() |
Helper | Extracts related model from ForeignKey/ManyToMany field |
_validate_non_relation_field() |
Helper | Validates non-relation field placement in path |
Applied to all filter mixins:
- IcontainsFilterViewSetMixin (lines 2886-2904)
- BooleanFilterViewSetMixin (lines 2907-2920)
- NumericFilterViewSetMixin (lines 2923-2936)
- DateFilterViewSetMixin (lines 2939-2952)
- RelationFilterViewSetMixin (lines 2955-2968)
- MatchCaseFilterViewSetMixin (lines 2971-2984)
Now blocks injection attempts:
?author___state__db=malicious # ❌ Now blocked (invalid lookup)
?author__password__icontains=admin # ❌ Now blocked (invalid field path)
🎯 Django Lookup Types
ninja_aio/types.py
Added DjangoLookup type and VALID_DJANGO_LOOKUPS set containing all 36 valid Django ORM lookup suffixes for validation.
Valid lookups:
- Equality: exact, iexact
- Comparison: gt, gte, lt, lte, range
- Text: contains, icontains, startswith, istartswith, endswith, iendswith, regex, iregex
- Boolean: isnull, in
- Date/Time: date, year, month, day, week, week_day, quarter, time, hour, minute, second
🚀 Performance Improvements
⚡ Schema Generation Caching
ninja_aio/models/serializers.py
Added @lru_cache(maxsize=128) to all schema generation methods, dramatically reducing repeated schema generation overhead.
Cached methods:
| Method | Line | Expected Speedup |
|---|---|---|
generate_read_s() |
1193 | 10-100x for repeated calls |
generate_detail_s() |
1207 | 10-100x for repeated calls |
generate_create_s() |
1225 | 10-100x for repeated calls |
generate_update_s() |
1238 | 10-100x for repeated calls |
generate_related_s() |
1252 | 10-100x for repeated calls |
Benefit: Schema generation is expensive (Pydantic model creation, validator collection, etc.). Since model structure is static, caching eliminates redundant work.
⚡ Relation Discovery Caching
ninja_aio/models/utils.py
Added class-level _relation_cache dictionary to cache discovered model relationships.
Cached methods:
| Method | Line | What It Caches |
|---|---|---|
get_reverse_relations() |
2575-2361 | Reverse ForeignKey and ManyToMany relations |
get_select_relateds() |
2621-2640 | Forward ForeignKey relations for select_related |
Benefit: Model relationships are static at runtime. Caching eliminates repeated model introspection overhead.
⚡ Parallel Field Processing
ninja_aio/models/utils.py
Refactored payload processing to use asyncio.gather() for parallel field resolution.
New method:
- _process_payload_fields() (lines 2546-2578) - Processes all fields in parallel
Applied in:
- parse_input_data() (lines 915-916) - Fetches all field objects and resolves all FK fields concurrently
Benefit: Significantly faster for payloads with multiple fields, especially when resolving foreign keys that require database lookups.
🧹 Code Quality Improvements
Reduced Cognitive Complexity in BaseSerializer
ninja_aio/models/serializers.py
Extracted helper methods from _generate_model_schema() to improve readability and maintainability.
New helper methods:
| Method | Line | Purpose |
|---|---|---|
_create_out_or_detail_schema() |
1092-1114 | Handles Out and Detail schema types |
_create_related_schema() |
1117-1132 | Handles Related schema type |
_create_in_or_patch_schema() |
1135-1147 | Handles In and Patch schema types |
Simplified main method:
- _generate_model_schema() (lines 1150-1184) - Now dispatches to appropriate helper based on schema type
Benefit: Reduced cognitive complexity, improved testability, clearer error handling paths.
Reduced Cognitive Complexity in ModelUtil
ninja_aio/models/utils.py
Extracted helper methods from parse_input_data() to improve readability and testability.
New helper methods:
| Method | Line | Purpose |

2478-2514 | Collects custom and optional fields from payload |
_determine_skip_keys() |
2516-2545 | Determines which keys to skip during processing |
_process_payload_fields() |
2546-2578 | Processes payload fields in parallel |
Added type hints and docstrings:
| Method | Line | Return Type |
|---|---|---|
_get_field() |
2640-2648 | models.Field |
_decode_binary() |
2650-2658 | None |
_resolve_fk() |
2660-2668 | None |

v2.18.0
Feb 01, 2026✨ New Features
🛡️ Validators on Serializers
ninja_aio/models/serializers.py
Pydantic @field_validator and @model_validator can now be declared directly on serializer configuration classes. The framework automatically collects PydanticDescriptorProxy instances and creates a subclass of the generated schema with the validators attached.
Supported on both serializer patterns:
| Pattern | Where to declare validators |
|---|---|
ModelSerializer |
Inner classes: CreateSerializer, ReadSerializer, UpdateSerializer, DetailSerializer |
Serializer (Meta-driven) |
Dedicated inner classes: CreateValidators, ReadValidators, UpdateValidators, DetailValidators |
🔀 Different validation rules can be applied per operation (e.g., stricter rules on create, lenient on update).
ModelSerializer example:
from django.db import models
from pydantic import field_validator, model_validator
from ninja_aio.models import ModelSerializer
class Book(ModelSerializer):
title = models.CharField(max_length=120)
description = models.TextField(blank=True)
class CreateSerializer:
fields = ["title", "description"]
@field_validator("title")
@classmethod
def validate_title_min_length(cls, v):
if len(v) < 3:
raise ValueError("Title must be at least 3 characters")
return v
class UpdateSerializer:
optionals = [("title", str), ("description", str)]
@field_validator("title")
@classmethod
def validate_title_not_empty(cls, v):
if v is not None and len(v.strip()) == 0:
raise ValueError("Title cannot be blank")
return v
Serializer (Meta-driven) example:
from pydantic import field_validator
from ninja_aio.models import serializers
class BookSerializer(serializers.Serializer):
class Meta:
model = Book
schema_in = serializers.SchemaModelConfig(fields=["title", "description"])
schema_out = serializers.SchemaModelConfig(fields=["id", "title", "description"])
class CreateValidators:
@field_validator("title")
@classmethod
def validate_title_min_length(cls, v):
if len(v) < 3:
raise ValueError("Title must be at least 3 characters")
return v
🧩 New Core Methods on BaseSerializer
ninja_aio/models/serializers.py
| Method | Description |
|---|---|
_collect_validators(source_class) |
🔍 Scans a class for PydanticDescriptorProxy instances created by @field_validator / @model_validator decorators. Returns a dict mapping attribute names to validator proxies. |
_apply_validators(schema, validators) |
🔗 Creates a subclass of the generated schema with validators attached. Pydantic discovers validators during class creation. |
_get_validators(schema_type) |
🗺️ Abstract method for subclasses to map schema types (In, Patch, Out, Detail, Related) to their validator source classes. |
🆕 New _parse_payload() Method on Serializer
ninja_aio/models/serializers.py
Serializer._parse_payload(payload) accepts both dict and Schema instances, automatically calling model_dump() on Schema inputs. This enables passing validated Pydantic schemas directly to create() and update().
📖 New Tutorial: "Define Your Serializer"
docs/tutorial/serializer.md
Comprehensive tutorial page for the Meta-driven Serializer approach as an alternative to Step 1 (ModelSerializer). Covers:
- 📐 Schema definition with
SchemaModelConfig - 🔗 Relationships via
relations_serializers - ⚙️ Custom and computed fields
- 🚀 Query optimizations with
QuerySet - 🔄 Lifecycle hooks
- 🔌 Connecting to
APIViewSet
📚 New Validators Documentation Page
docs/api/models/validators.md
Full dedicated documentation page covering:
- 🏗️
ModelSerializerandSerializerapproaches - ✅ Supported validator types and modes
- 🔀 Different validators per operation
- ⚙️ Internal mechanics
- ⚠️ Error handling (422 responses)
- 💡 Complete examples
🔧 Improvements
⚡ Schema Generation Now Applies Validators
ninja_aio/models/serializers.py
_generate_model_schema() now calls _get_validators() for the requested schema type and _apply_validators() on the resulting schema. Applied consistently across all schema types: Out, Detail, Related, In, and Patch.
📦 create() and update() Accept Schema Objects
ninja_aio/models/serializers.py
Serializer.create() and Serializer.update() payload parameter type changed from dict[str, Any] to dict[str, Any] | Schema, using the new _parse_payload() method to handle both inputs transparently.
🏷️ Updated Type Annotations
ninja_aio/models/serializers.py
ModelSerializerinner classes now accepttuple[str, Any]in addition totuple[str, Any, Any]for bothfieldsandcustomsattributes.SchemaModelConfig.customstype annotation updated toList[tuple[str, Any, Any] | tuple[str, Any]].
📝 Comprehensive Docstrings

🎯 Summary
This release introduces Pydantic validators on serializers, allowing @field_validator and @model_validator to be declared directly on serializer configuration classes. The framework automatically collects and applies these validators to generated schemas. Additionally, the entire documentation site has been redesigned with Material for MkDocs components.
🌟 Key benefits:
- 🛡️ Schema-level validation — Enforce input constraints beyond Django model fields, running before data touches the database
- 🔀 Per-operation validation — Apply different validation rules per CRUD operation (create vs. update vs. read)
- 🏗️ Both serializer patterns — Works with
ModelSerializer(inner classes) andSerializer({Type}Validatorsclasses) - ♻️ Backwards compatible — Existing serializers without validators continue to work unchanged
- 🎨 Documentation redesign — Modern Material for MkDocs layout with grid cards, hero sections, and interactive release notes
v2.17.0
Jan 28, 2026✨ New Features
- Inline Custom Fields in
fieldsList [ninja_aio/models/serializers.py]: - Custom fields can now be defined directly in the
fieldslist as tuples, providing a more concise syntax. - Supports both 2-tuple
(name, type)for required fields and 3-tuple(name, type, default)for optional fields. - Works with both
ModelSerializer(inner classes) andSerializer(Meta-driven) approaches. - Applies to all serializer types:
CreateSerializer,ReadSerializer,DetailSerializer,UpdateSerializer, andSchemaModelConfig.
Usage example (ModelSerializer):
```python
from ninja_aio.models import ModelSerializer
class Article(ModelSerializer):
title = models.CharField(max_length=200)
content = models.TextField()
class ReadSerializer:
fields = [
"id",
"title",
("word_count", int, 0), # 3-tuple: optional with default
("is_featured", bool), # 2-tuple: required field
]
```
Usage example (Serializer):
```python
from ninja_aio.models import serializers
class ArticleSerializer(serializers.Serializer):
class Meta:
model = Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", ("reading_time", int, 0)]
)
```
- New
get_inline_customs()Helper Method [ninja_aio/models/serializers.py]: - Added
BaseSerializer.get_inline_customs(s_type)method to extract and normalize inline custom tuples from thefieldslist. - Returns a list of normalized 3-tuples
(name, type, default), converting 2-tuples by adding...(Ellipsis) as the default.
🔧 Improvements
- Refactored
get_fields()Method [ninja_aio/models/serializers.py]: get_fields()now returns only string field names, excluding inline custom tuples.-
Clearer separation of concerns between model fields and custom fields.
-
Improved
get_related_schema_data()Method [ninja_aio/models/serializers.py]: - Fixed handling of custom fields that don't exist as model attributes.
-
Custom fields (both explicit and inline) are now always included in related schemas since they are computed/synthetic.
-
Updated
SchemaModelConfigType Annotations [ninja_aio/models/serializers.py]: - The
fieldsattribute now acceptsList[str | tuple[str, Any, Any] | tuple[str, Any]]to support inline customs. -
Updated docstring to document the new tuple formats.
-
Cleaner Schema Generation [
ninja_aio/models/serializers.py]: get_schema_out_data()and_generate_model_schema()now use the newget_inline_customs()helper, reducing code duplication.
🧪 Tests
- New Inline Customs Test Cases [
tests/test_serializers.py]: -
Added

-
New Test Model [
tests/test_app/models.py]: - Added

list[str | tuple]type forfields. - Added "Inline Custom Fields" subsection in CreateSerializer with usage example.
- Updated ReadSerializer, DetailSerializer, and UpdateSerializer tables.
📋 Summary
This minor release introduces inline custom field support, allowing custom/computed fields to be defined directly in the fields list as tuples. This provides a more concise syntax for simple custom fields while maintaining full backwards compatibility with the separate customs list approach.
Key Benefits
- Concise syntax: Define simple custom fields inline without a separate
customslist - Flexibility: Mix regular fields and custom tuples in the same list
- Backwards compatible: Existing code using
customslist continues to work unchanged

v2.16.2
Jan 27, 2026🐛 Bug Fixes
- Fixed Schema Generation with Only Custom Fields [
ninja_aio/models/serializers.py]: - Fixed an issue in
_generate_model_schema()where defining onlycustomsand/oroptionals(without explicitfieldsorexcludes) would incorrectly include all model fields in the generated schema. - When only custom fields are defined, the schema now correctly excludes all concrete model fields, returning a schema with only the specified custom fields.
- This fix applies to both
Serializer(Meta-driven) andModelSerializercreate/update schema generation.
Before (broken behavior):
```python
class MySerializer(Serializer):
class Meta:
model = MyModel
schema_in = SchemaModelConfig(
customs=[("custom_input", str, ...)]
)
# Generated schema incorrectly included ALL model fields + custom_input
```
After (fixed behavior):
```python
class MySerializer(Serializer):
class Meta:
model = MyModel
schema_in = SchemaModelConfig(
customs=[("custom_input", str, ...)]
)
# Generated schema now correctly includes ONLY custom_input
```
🔧 Improvements
- Union Type Support in SchemaModelConfig [
ninja_aio/models/serializers.py]: - Updated
optionalsandcustomsfield type hints inSchemaModelConfigto acceptAnyinstead oftype. - This allows using Union types and other complex type annotations in schema configurations.
Usage example:
```python
from typing import Union
schema_in = SchemaModelConfig(
optionals=[("status", str | None)],
customs=[
("data", Union[str, int], None),
("items", list[int], []),
],
)
```
🧪 Tests
- New Custom Fields Schema Tests [
tests/test_serializers.py]: - Added
CustomsOnlySchemaTestCasetest class with 7 new tests:test_serializer_create_schema_with_only_customs: Verifies create schema with only customs excludes model fields.test_serializer_update_schema_with_only_customs: Verifies update schema with only customs excludes model fields.test_serializer_create_schema_with_customs_and_optionals: Verifies customs + optionals includes only those fields.test_serializer_with_fields_still_works: Confirms explicit fields behavior is preserved.test_serializer_with_only_excludes_and_customs: Documents behavior when excludes defined without fields.test_serializer_empty_schema_returns_none: Verifies empty schema returns None.test_serializer_multiple_customs_no_model_fields: Verifies multiple customs work without model fields.
📋 Summary
This patch release fixes a bug where schemas defined with only custom fields would incorrectly include all model fields, and adds support for Union types in SchemaModelConfig field definitions.

✨ New Features
- Custom Decorators for M2M Relation Endpoints [
ninja_aio/schemas/helpers.py,ninja_aio/helpers/api.py]: - Added
get_decoratorsfield toM2MRelationSchemafor applying custom decorators to GET (list related objects) endpoints. - Added
post_decoratorsfield toM2MRelationSchemafor applying custom decorators to POST (add/remove) endpoints. - Decorators are unpacked and applied via
decorate_view()alongside existing decorators likeunique_viewandpaginate. - Enables use cases such as rate limiting, caching, custom authentication, logging, or any other decorator-based middleware on M2M endpoints.
Usage example:
```python
from ninja_aio.schemas import M2MRelationSchema
M2MRelationSchema(
model=RelatedModel,
related_name="related_items",
get_decorators=[cache_decorator, log_decorator],
post_decorators=[rate_limit_decorator],
)
```
🔧 Improvements
- Refactored Manage Relation View Registration [
ninja_aio/helpers/api.py]: - Updated
_register_manage_relation_view()to usedecorate_view()wrapper instead of direct@unique_viewdecorator. - Ensures consistent decorator application pattern between GET and POST endpoints.
-
Allows decorator spreading via
*decoratorsfor extensibility. -
Improved Type Hints [
ninja_aio/schemas/helpers.py]: - Added
Callableimport from typing module. - Updated
get_decoratorsandpost_decoratorstype hints toOptional[List[Callable]]for better IDE support and type checking.
🧪 Tests
- New Decorator Integration Tests [
tests/helpers/test_many_to_many_api.py]: - Added
M2MRelationSchemaDecoratorsTestCasetest class with integration tests:test_get_decorator_is_applied: Verifies GET decorators are invoked on list endpoint calls.test_post_decorator_is_applied: Verifies POST decorators are invoked on add/remove endpoint calls.test_decorators_independent: Confirms GET and POST decorators operate independently.
-
Added
TestM2MWithDecoratorsViewSettest viewset demonstrating decorator usage. -
New Decorator Schema Validation Tests [
tests/helpers/test_many_to_many_api.py]: - Added
M2MRelationSchemaDecoratorsFieldTestCasetest class with schema field tests:test_decorators_default_to_empty_list: Validates default empty list behavior.test_decorators_accept_list_of_callables: Validates callable list acceptance.test_decorators_can_be_none: Validates explicitNoneassignment.
📚 Documentation
- Updated APIViewSet Documentation [
docs/api/views/api_view_set.md]: - Added
get_decoratorsandpost_decoratorsto M2MRelationSchema attributes list. - Added comprehensive example showing custom decorator usage with M2M relations (cache and rate limiting patterns).
-
Added note explaining decorator application order and interaction with built-in decorators.
-
Updated Decorators Documentation [
docs/api/views/decorators.md]: - Added new "M2MRelationSchema decorators" section.
-
Included usage example and cross-reference to APIViewSet M2M Relations documentation.
-
Split Quick Start into Two Guides:
- [
docs/getting_started/quick_start.md]: Dedicated toModelSerializerapproach with embedded serializer configuration. - [
docs/getting_started/quick_start_serializer.md]: New guide forSerializerapproach with plain Django models, including examples for relationships, query optimization, and lifecycle hooks.
📋 Summary
This minor release introduces custom decorator support for Many-to-Many relation endpoints. Users can now apply custom decorators independently to GET and POST M2M endpoints via the new get_decorators and post_decorators fields in M2MRelationSchema. This enables flexible middleware patterns such as caching, rate limiting, and custom logging on relation endpoints.

🧪 Tests
- New Custom Fields Schema Tests [
tests/test_serializers.py]: - Added
CustomsOnlySchemaTestCasetest class with 7 new tests:test_serializer_create_schema_with_only_customs: Verifies create schema with only customs excludes model fields.test_serializer_update_schema_with_only_customs: Verifies update schema with only customs excludes model fields.test_serializer_create_schema_with_customs_and_optionals: Verifies customs + optionals includes only those fields.test_serializer_with_fields_still_works: Confirms explicit fields behavior is preserved.test_serializer_with_only_excludes_and_customs: Documents behavior when excludes defined without fields.test_serializer_empty_schema_returns_none: Verifies empty schema returns None.test_serializer_multiple_customs_no_model_fields: Verifies multiple customs work without model fields.
📋 Summary
This patch release fixes a bug where schemas defined with only custom fields would incorrectly include all model fields. The fix ensures that when only customs are specified (without fields or excludes), the generated schema contains only the custom fields as intended.

v2.15.1
Jan 26, 2026🐛 Fixed
- JWT Exception Handling in AsyncJwtBearer [
ninja_aio/auth.py]: - Updated exception handling to catch
errors.JoseErrorinstead ofValueErrorfor JWT decoding failures. - Removed redundant nested try-except block that separately handled
ValueErrorduring token decode. - JWT decode and claims validation are now consolidated into a single exception handler.
- Ensures consistent error handling across all JWT-related failures including malformed tokens, invalid signatures, and claim validation errors.
🔧 Improvements
- Streamlined Readable Fields Resolution in BaseSerializer [
ninja_aio/models/serializers.py]: - Refactored
_resolve_relation_schema()to use a single-line conditional expression for resolvingModelSerializerwith readable fields. -
Simplified from separate if-else blocks to a cleaner ternary pattern:
return rel_model.generate_related_s() if has_readable_fields else None. -
Optimized Condition for Skipping ModelSerializer [
ninja_aio/models/serializers.py]: - Combined nested conditionals in
_build_related_field()into a single compound conditional statement. - Checking for
ModelSerializerinstances with no readable fields is now a unified expression. - Improves code clarity without changing behavior.
🧪 Tests
- Updated JWT Authentication Tests [
tests/test_auth.py]: - Updated mock to raise
JoseErrorinstead ofValueErrorto align with the corrected exception handling inAsyncJwtBearer. -
Ensures test coverage accurately reflects the authentication error flow.
-
Fixed Schema Variable Warning in Tests [
tests/test_auth.py]: - Updated
DetailSchemaModelSerializerTestCaseto ignore unused schema variables.
📋 Summary
This patch release focuses on code quality improvements and a bug fix in JWT authentication. The AsyncJwtBearer class now correctly handles all JWT-related exceptions through the joserfc.errors.JoseError hierarchy, and the serializer codebase has been refactored for improved readability.

v2.15.0
Jan 22, 2026New Features
- Dynamic PK Type Detection for
relations_as_id[ninja_aio/models/serializers.py]: - The
PkFromModeltype now automatically detects and uses the related model's primary key type. - Supports
int(default),UUID,str(CharField), and any other Django primary key type. - Schema generation now correctly annotates relation fields with the appropriate PK type.
Improvements
PkFromModelSubscriptable Type [ninja_aio/models/serializers.py]:- New
PkFromModel[type]syntax allows explicit PK type specification. - Examples:
PkFromModel[int],PkFromModel[UUID],PkFromModel[str]. - Falls back to
intwhen used without subscription (backwards compatible). - Uses
BeforeValidatorto extractpkattribute during Pydantic serialization.
Tests
- Comprehensive Test Coverage for Different PK Types [
tests/test_serializers.py]: - Added
RelationsAsIdUUIDModelSerializerTestCase(6 tests) - Schema generation tests for UUID PKs - Added
RelationsAsIdUUIDIntegrationTestCase(7 tests) - Integration tests with UUID PK data - Added
RelationsAsIdStringPKModelSerializerTestCase(6 tests) - Schema generation tests for string PKs - Added
RelationsAsIdStringPKIntegrationTestCase(7 tests) - Integration tests with string PK data -
Coverage includes all relation types: Forward FK, Reverse FK, Forward O2O, Reverse O2O, Forward M2M, Reverse M2M
-
New Test Models with Different PK Types [
tests/test_app/models.py]: - UUID PK models:
AuthorUUID,BookUUID,ProfileUUID,UserUUID,TagUUID,ArticleUUID - String PK models:
AuthorStringPK,BookStringPK,ProfileStringPK,UserStringPK,TagStringPK,ArticleStringPK
Documentation
- ModelSerializer Documentation [
docs/api/models/model_serializer.md]: - Updated
relations_as_idtable to showPK_TYPEinstead of hardcodedint. - Added note explaining automatic PK type detection.
-
Added UUID primary key example with code and JSON output.
-
Serializer Documentation [
docs/api/models/serializers.md]: - Updated
relations_as_idtable to showPK_TYPEinstead of hardcodedint. - Added note explaining automatic PK type detection.
- Added UUID primary key example with code and JSON output.
Usage Example
UUID Primary Key with relations_as_id
import uuid
from django.db import models
from ninja_aio.models import ModelSerializer
class Author(ModelSerializer):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
name = models.CharField(max_length=200)
class ReadSerializer:

v2.14.0
Jan 22, 2026🐛 Fixed
- Forward Relations in
relations_as_idNow Work Correctly [ninja_aio/models/serializers.py]: - Fixed issue where forward FK and O2O relations listed in
relations_as_idwere serialized asnullinstead of the related object's ID. - Root Cause: Previously used
validation_aliaswhich only affects input parsing, not output serialization. - Solution: Now uses
PkFromModelwithBeforeValidatorto extract the primary key during serialization, consistent with reverse relations. - Affects: Forward ForeignKey, Forward OneToOneField.
🔧 Improvements
- Optimized
relations_as_idProcessing [ninja_aio/models/serializers.py]: _get_relations_as_id()is now called once inget_schema_out_data()and passed through to child methods, eliminating redundant method calls during schema generation.-
_build_schema_reverse_rel(),_build_schema_forward_rel(), and_process_field()now acceptrelations_as_idas a parameter instead of fetching it independently. -
Enhanced Method Documentation [
ninja_aio/models/serializers.py]: - Added comprehensive docstrings with parameter descriptions to:
_build_schema_reverse_rel()- Documents descriptor types and return values_build_schema_forward_rel()- Documents forward relation handling logic_process_field()- Documents field classification processget_schema_out_data()- Documents schema component collection
🧪 Tests

📖 Documentation
- ModelSerializer Documentation [
docs/api/models/model_serializer.md]: - Added
relations_as_idattribute toReadSerializerattributes table. -
Added new "Relations as ID" section with:

💡 Usage Example
ModelSerializer with relations_as_id
from ninja_aio.models import ModelSerializer
from django.db import models
class Author(ModelSerializer):
name = models.CharField(max_length=200)
class ReadSerializer:
fields = ["id", "name", "books"]
relations_as_id = ["books"] # Reverse FK as list of IDs
class Book(ModelSerializer):
title = models.CharField(max_length=200)
author = models.ForeignKey(Author, on_delete=models.CASCADE, related_name="books")
class ReadSerializer:
fields = ["id", "title", "author"]
relations_as_id = ["author"] # Forward FK as ID
Output (Author):
{
"id": 1,
"name": "J.K. Rowling",
"books": [1, 2, 3]
}
Output (Book):
{
"id": 1,
"title": "Harry Potter",
"author": 1
}
Meta-driven Serializer with relations_as_id
from ninja_aio.models import serializers
class ArticleSerializer(serializers.Serializer):
class Meta:
model = Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "author", "tags"]
)
relations_serializers = {
"author": AuthorSerializer, # Nested object
}
relations_as_id = ["tags"] # M2M as list of IDs
class QuerySet:
read = ModelQuerySetSchema(
select_related=["author"],
prefetch_related=["tags"],
)
Output:
{
"id": 1,
"title": "Getting Started with Django",
"author": {"id": 1, "name": "John Doe"},
"tags": [1, 2, 5]
}
v2.13.0
Jan 21, 2026✨ Added
verbose_name_pluralAttribute for M2MRelationSchema [ninja_aio/schemas/helpers.py]:- New optional
verbose_name_pluralfield allows customizing the human-readable plural name for M2M relation endpoints. - When provided, used in endpoint summaries and descriptions (e.g.,
"Get Article Tags","Add or Remove Article Tags"). - Falls back to
model._meta.verbose_name_plural.capitalize()when not specified.
🔧 Improvements
- Refactored M2M Endpoint Summary Generation [
ninja_aio/helpers/api.py]: _register_get_relation_view()now acceptsverbose_name_pluralparameter instead of computing it internally._register_manage_relation_view()simplified by removingrel_utilparameter; now receivesverbose_name_pluraldirectly._build_views()centralizes verbose name resolution with fallback logic.-
Cleaner separation of concerns: verbose name is resolved once and passed to both GET and POST registration methods.
-
Simplified Warning Logic for Missing Relation Serializers [
ninja_aio/models/serializers.py]: _warn_missing_relation_serializer()now uses simpler boolean logic.- Warnings emit when model is not a
ModelSerializerandNINJA_AIO_RAISE_SERIALIZATION_WARNINGSisTrue(default). - Removed dependency on
NINJA_AIO_TESTINGsetting for warning control.
📖 Documentation
- Updated M2MRelationSchema Documentation [
docs/api/views/api_view_set.md]: - Added
verbose_name_pluralto the list of M2MRelationSchema attributes. - Added usage example demonstrating custom verbose names for M2M endpoints.
💡 Usage Example
Custom Verbose Names for M2M Endpoints
from ninja_aio.views import APIViewSet
from ninja_aio.schemas.helpers import M2MRelationSchema
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
m2m_relations = [
M2MRelationSchema(
model=Tag,
related_name="tags",
verbose_name_plural="Article Tags", # Custom name
add=True,
remove=True,
get=True,
),
M2MRelationSchema(
model=Category,
related_name="categories",
# Uses default: "Categories" (from model._meta.verbose_name_plural)
get=True,
),
]
Generated Endpoint Summaries:
- GET /articles/{pk}/tags → Summary: "Get Article Tags"
- POST /articles/{pk}/tags/ → Summary: "Add or Remove Article Tags"
- GET /articles/{pk}/categories → Summary: "Get Categories"
v2.12.3
Jan 21, 2026🐛 Fixed
- Warning Logic for Missing Relation Serializers [
ninja_aio/models/serializers.py]: - Fixed boolean logic in
_warn_missing_relation_serializermethod.
v2.12.2
Jan 21, 2026🐛 Fixed
- Warning Logic for Missing Relation Serializers [
ninja_aio/models/serializers.py]: - Fixed boolean logic in
_warn_missing_relation_serializermethod. - Warnings now correctly emit when: (not ModelSerializer AND not testing) OR force warnings enabled.
- Previously, warnings were incorrectly suppressed for non-ModelSerializer relations even when
NINJA_AIO_RAISE_SERIALIZATION_WARNINGS=True.
v2.12.1
Jan 21, 2026🐛 Fixed
- QueryUtil DETAIL Scope Fallback [
ninja_aio/helpers/query.py]: detail_confignow correctly falls back toread_configforselect_relatedandprefetch_relatedwhen not explicitly configured.- Ensures consistent queryset optimization behavior between READ and DETAIL scopes.
🔧 Improvements
- Refactored Fallback Logic [
ninja_aio/helpers/query.py]: - Moved DETAIL→READ fallback from
apply_queryset_optimizations()to__init__(). - Fallback is now resolved once at construction time, improving clarity and preventing runtime mutation.
- Uses
.copy()to ensuredetail_configlists are independent fromread_config.
🧪 Tests
- New Test Cases for QueryUtil DETAIL Fallback [
tests/test_query_util.py]: test_detail_scope_fallback_to_read_select_related: Verifies DETAIL scope uses READ'sselect_relatedwhen not configured.test_detail_scope_fallback_to_read_prefetch_related: Verifies DETAIL scope uses READ'sprefetch_relatedwhen not configured.test_detail_config_initialized_with_read_fallback: Confirms fallback is applied during initialization.test_detail_config_independent_copy: Ensuresdetail_configlists are copies, not references (prevents mutation bugs).
v2.12.0
Jan 21, 2026✨ Added
- Per-Field-Type Detail Fallback for ModelSerializer [
ninja_aio/models/serializers.py]: DetailSerializernow falls back toReadSerializerfor each field type (fields,customs,optionals,excludes) independently when not explicitly configured.-
Allows partial overrides: define only
DetailSerializer.fieldswhile inheritingcustoms,optionals, andexcludesfromReadSerializer. -
Schema-Level Detail Fallback for Serializer [
ninja_aio/models/serializers.py]: - When
schema_detailis not defined,Serializernow correctly falls back toschema_outfor all field configurations. -
Enables seamless list/detail endpoint differentiation without duplicating configuration.
-
New Setting:
NINJA_AIO_RAISE_SERIALIZATION_WARNINGS[ninja_aio/models/serializers.py]: - New Django setting to control serialization warning behavior during testing.
- When
True(withNINJA_AIO_TESTING=True), warnings for missing relation serializers are raised instead of suppressed.
🔧 Improvements
- Refactored Fallback Logic [
ninja_aio/models/serializers.py]: - Moved detail→read fallback from
BaseSerializer.get_fields()to_get_fields()in bothModelSerializerandSerializer. ModelSerializer._get_fields(): Falls back per-field-type (ifDetailSerializer.customsis empty, usesReadSerializer.customs).-
Serializer._get_fields(): Falls back at schema level (ifschema_detailisNone, usesschema_out). -
Warning Control Enhancement [
ninja_aio/models/serializers.py]: - Updated
_warn_missing_relation_serializer()to respect bothNINJA_AIO_TESTINGand newNINJA_AIO_RAISE_SERIALIZATION_WARNINGSsettings.
🐛 Fixed
- Serializer Detail Fallback Typo [
ninja_aio/models/serializers.py]: - Fixed
Serializer._get_fields()where detail fallback was incorrectly referencing"read"instead of"out"schema key.
🧪 Tests
- New Test Cases for Serializer Detail Fallback [
tests/test_serializers.py]: test_detail_fallback_customs_from_read: Verifies customs inheritance whenschema_detailis not defined.test_detail_fallback_optionals_from_read: Verifies optionals inheritance.test_detail_fallback_excludes_from_read: Verifies excludes inheritance.-
test_detail_does_not_inherit_when_defined: Confirms no inheritance whenschema_detailis explicitly defined. -
New Test Cases for ModelSerializer Detail Fallback [
tests/test_serializers.py]: test_model_serializer_detail_fallback_fields: Verifies fields fallback toReadSerializer.test_model_serializer_detail_fallback_customs: Verifies customs fallback per-field-type.test_model_serializer_detail_fallback_optionals: Verifies optionals fallback per-field-type.test_model_serializer_detail_fallback_excludes: Verifies excludes fallback per-field-type.test_model_serializer_detail_inherits_per_field_type: Confirms per-field-type inheritance behavior.-
test_model_serializer_with_detail_generates_different_schemas: End-to-end schema generation test. -
New Test Models [
tests/test_app/models.py]: TestModelSerializerWithReadCustoms: Model with customs onReadSerializeronly.TestModelSerializerWithReadOptionals: Model with optionals onReadSerializeronly.TestModelSerializerWithReadExcludes: Model with excludes onReadSerializeronly.TestModelSerializerWithBothSerializers: Model with bothReadSerializerandDetailSerializerconfigured.
💡 Usage Example
ModelSerializer (Per-Field-Type Fallback)
from ninja_aio.models import ModelSerializer
from django.db import models
class Article(ModelSerializer):
title = models.CharField(max_length=200)
content = models.TextField()
author_notes = models.TextField(blank=True)
class ReadSerializer:
fields = ["id", "title"]
customs = [("word_count", int, lambda obj: len(obj.content.split()))]
class DetailSerializer:
# Only override fields - customs inherited from ReadSerializer
fields = ["id", "title", "content", "author_notes"]
Behavior:
- generate_read_s() → {"id", "title", "word_count"}
- generate_detail_s() → {"id", "title", "content", "author_notes", "word_count"} (customs inherited)
Serializer (Schema-Level Fallback)
from ninja_aio.models import serializers
class ArticleSerializer(serializers.Serializer):
class Meta:
model = Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title"],
customs=[("word_count", int, 0)],
)
# No schema_detail - falls back to schema_out entirely
Behavior:
- generate_read_s() → {"id", "title", "word_count"}
- generate_detail_s() → {"id", "title", "word_count"} (same as read)

_bump_object_from_schema- removedmode="json"frommodel_dump()to prevent UTF-8 decode errors when retrieving binary data. Binary fields are now properly handled byORJSONRendererwhich converts them to base64.
v2.11.1
Jan 19, 2026🐛 Bug Fixes
- ORJSONRenderer HttpResponse Passthrough [
ninja_aio/renders.py]: - Fixed
ORJSONRenderer.render()to detect and returnHttpResponseBaseinstances directly without JSON serialization. - Previously, returning an
HttpResponsewith a custom content type (e.g., PEM files, binary downloads) would fail because the renderer attempted to serialize it as JSON. - Now supports returning
HttpResponse,StreamingHttpResponse, and any otherHttpResponseBasesubclass.
📖 Documentation
- ORJSON Renderer Documentation [
docs/api/renderers/orjson_renderer.md]: - Reorganized documentation with proper section headings.
- Added new HttpResponse Passthrough section explaining the feature.
- Includes usage examples for
HttpResponseandStreamingHttpResponse. - Documents the correct pattern for returning custom responses with non-JSON content types.
🧪 Tests
- New Test Cases [
tests/core/test_renderer_parser.py]: test_renderer_http_response_passthrough: VerifiesHttpResponseobjects pass through unchanged with correct content and headers.test_renderer_streaming_http_response_passthrough: VerifiesStreamingHttpResponseobjects are also handled correctly.
💡 Usage Example
from django.http import HttpResponse, StreamingHttpResponse
# Return a PEM file
@api.get("/public-key")
def get_public_key(request):
return HttpResponse(
settings.JWT_PUBLIC_KEY.as_pem(),
content_type="application/x-pem-file",
status=200,
)
# Return a streaming response for large files
@api.get("/download")
def download_file(request):
return StreamingHttpResponse(
file_iterator(),
content_type="application/octet-stream",
)
Note: Set the
statusparameter on theHttpResponseitself. Do not use tuple returns likereturn 200, HttpResponse(...).
v2.11.0
Jan 19, 2026✨ Added
- MatchCaseFilterViewSetMixin [
ninja_aio/views/mixins.py]: - New mixin for conditional filtering based on boolean query parameters.
- Maps boolean API parameters (
?is_active=true) to different Django ORM filter conditions forTrueandFalsecases. - Supports both
filter()(include) andexclude()operations via theincludeattribute. -
Automatically registers query params from
filters_match_casesconfiguration. -
New Filter Schemas [
ninja_aio/schemas/filters.py]: MatchCaseFilterSchema: Configures match-case filters withquery_paramandcasesattributes.MatchConditionFilterSchema: Defines individual filter conditions withquery_filter(dict) andinclude(bool).BooleanMatchFilterSchema: Groupstrueandfalsecase conditions.FilterSchema: New base class for filter schemas withfilter_typeandquery_paramattributes.
🔧 Improvements
- Unified Special Filter Detection [
ninja_aio/views/api.py]: - Added
APIViewSet._check_match_cases_filters(filter: str)helper method. -
Added
APIViewSet._is_special_filter(filter: str)method combining relation and match-case filter detection. -
Filter Mixin Skip Logic [
ninja_aio/views/mixins.py]: - Updated all filter mixins to use
_is_special_filter()instead of_check_relations_filters():IcontainsFilterViewSetMixinBooleanFilterViewSetMixinNumericFilterViewSetMixinDateFilterViewSetMixin
-
Ensures match-case filter params are not double-processed by type-based mixins.
-
RelationFilterSchema Refactoring [
ninja_aio/schemas/filters.py]: RelationFilterSchemanow extendsFilterSchemabase class.- Moved from
ninja_aio/schemas/api.pyto dedicatedninja_aio/schemas/filters.pymodule.
📖 Documentation
- Mixins Documentation [
docs/api/views/mixins.md]: - Added comprehensive documentation for
MatchCaseFilterViewSetMixin. - Includes usage examples for simple status filtering and complex multi-condition filtering.
- Documents all schema requirements and configuration options.
🧪 Tests
- New Test Cases [
tests/views/test_viewset.py]: MatchCaseFilterViewSetMixinTestCase: Tests include behavior withTrue/False/Nonevalues.MatchCaseFilterViewSetMixinExcludeTestCase: Tests exclude behavior wheninclude=False.-
Tests cover query params registration and
filters_match_cases_fieldsproperty. -
Test ViewSets [
tests/test_app/views.py]: TestModelSerializerMatchCaseFilterAPI: Testsis_approvedfilter with include/exclude logic.-
TestModelSerializerMatchCaseExcludeFilterAPI: Testshide_pendingfilter with inverse logic. -
Test Model Update [
tests/test_app/models.py]: - Added
statusfield toTestModelSerializerfor match-case filter testing.
💡 Usage Example
from ninja_aio.views.mixins import MatchCaseFilterViewSetMixin
from ninja_aio.views.api import APIViewSet
from ninja_aio.schemas import (
MatchCaseFilterSchema,
MatchConditionFilterSchema,
BooleanMatchFilterSchema,
)
class OrderViewSet(MatchCaseFilterViewSetMixin, APIViewSet):
model = models.Order
api = api
filters_match_cases = [
MatchCaseFilterSchema(
query_param="is_completed",
cases=BooleanMatchFilterSchema(
true=MatchConditionFilterSchema(
query_filter={"status": "completed"},
),
false=MatchConditionFilterSchema(
query_filter={"status": "completed"},
include=False, # excludes completed orders
),
),
),
]
API Behavior:
- GET /orders?is_completed=true → queryset.filter(status="completed")
- GET /orders?is_completed=false → queryset.exclude(status="completed")
v2.10.1
Jan 16, 2026🐛 Fixed
- Filter Mixin Conflict Resolution [file:2]:
- Added
APIViewSet._check_relations_filters(filter: str)helper method to detect if a filter key belongs torelations_filters. -
Added
RelationFilterViewSetMixin.relations_filters_fieldsproperty that extracts allquery_paramnames from configuredrelations_filters. -
Filter Handler Skip Logic [file:2]:
- IcontainsFilterViewSetMixin: Now skips relation filter keys (
if isinstance(value, str) and not self._check_relations_filters(key)). - BooleanFilterViewSetMixin: Now skips relation filter keys when applying boolean filters.
- NumericFilterViewSetMixin: Now skips relation filter keys when applying numeric filters.
- DateFilterViewSetMixin: Now skips relation filter keys when applying date comparisons (
__lte, etc.).
Impact: Prevents double-processing of relation filters when combining RelationFilterViewSetMixin with other filter mixins. Relation filters are handled exclusively by RelationFilterViewSetMixin.query_params_handler, avoiding conflicts like:
- String relation params (?author_id=5) being misinterpreted as icontains filters.
- Numeric relation params being applied twice.
- Boolean/date relation params triggering incorrect transformations.
🔧 Internal Changes
- Mixin Inheritance Chain:
- Filter mixins (
IcontainsFilterViewSetMixin, etc.) now respectRelationFilterViewSetMixinconfiguration via shared_check_relations_filters()method. -
Ensures proper layering: base filters → relation filters (exclusive handling).
-
Query Params Handler Flow:
v2.10.0
Jan 16, 2026✨ Added
- Relation-Based Filtering Mixin:
- New
RelationFilterViewSetMixinfor filtering by related model fields via query parameters. - New
RelationFilterSchemafor declarative mapping ofquery_param→ Django ORMquery_filterwith typedfilter_typetuples. -
Automatic registration of
relations_filtersentries intoquery_paramson subclasses. -
Schema & Import Enhancements:
- Exported
RelationFilterSchemafromninja_aio.schemasand added to__all__. - Added
RelationFilterSchemaimport toninja_aio.views.mixinsand example usages in docs and test views.
🛠 Changed
- ModelUtil Relation Detection Fix:
- Corrected relation ordering in
ModelUtil.get_select_relateds():- Now detects
ForwardOneToOneDescriptorbeforeForwardManyToOneDescriptorfor buildingselect_relatedlists.
- Now detects
-
Ensures one-to-one relations are properly included in query optimizations.
-
Documentation Updates:
- Extended
docs/api/views/mixins.mdwith a new section forRelationFilterViewSetMixin. - Added examples showing how to configure
relations_filtersand resulting query behavior.
🐛 Fixed
- ModelUtil Primary Key Type Error Handling:
ModelUtil.pk_field_typenow raises a clearConfigErrorwhen encountering unknown primary key field types.-
Error message explicitly reports unsupported field type and suggests missing mapping in
ninja.orm.fields.TYPES. -
ModelUtil Configuration Edge Cases:
-
ModelUtilnow raisesConfigErrorwhen instantiated with aModelSerializermodel and an explicitserializer_classat the same time, avoiding ambiguous configuration. -
ORJSON Renderer Primitive Handling:
- ORJSON renderer now correctly handles non-dict payloads (strings, lists, primitives) without assuming
.items()presence. -
Added coverage for list and primitive responses to ensure consistent rendering behavior.
-
Async JWT Auth Robustness:
AsyncJwtBearer.authenticatenow safely handles invalid or malformed tokens wherejwt.decoderaisesValueError, returningFalseinstead of propagating the exception.- Base
auth_handlerpath verified to returnNonewhen not overridden, and mandatory claims validation now preserves pre-setissandaudvalues.
🧪 Tests
- New Test Suites for Edge Cases:

🚀 Use Cases & Examples
Detail-Specific Query Optimizations
from ninja_aio.models import ModelSerializer
from ninja_aio.schemas.helpers import ModelQuerySetSchema
class Article(ModelSerializer):
title = models.CharField(max_length=200)
summary = models.TextField()
content = models.TextField()
author = models.ForeignKey(User, on_delete=models.CASCADE)
tags = models.ManyToManyField(Tag)
comments = models.ManyToManyField(Comment)
class ReadSerializer:
# List view: minimal fields
fields = ["id", "title", "summary", "author"]
class DetailSerializer:
# Detail view: all fields including expensive relations
fields = ["id", "title", "summary", "content", "author", "tags", "comments"]
class QuerySet:
# Optimizations for list endpoint
read = ModelQuerySetSchema(
select_related=["author"],
prefetch_related=[],
)
# Optimizations for retrieve endpoint (more aggressive prefetching)
detail = ModelQuerySetSchema(
select_related=["author", "author__profile"],
prefetch_related=["tags", "comments", "comments__author"],
)
Behavior:
- GET /articles/ uses QuerySet.read optimizations (light prefetching)
- GET /articles/{pk} uses QuerySet.detail optimizations (full prefetching)
Fallback Behavior
class Article(ModelSerializer):
class ReadSerializer:
fields = ["id", "title", "content"]
class QuerySet:
read = ModelQuerySetSchema(
select_related=["author"],
prefetch_related=["tags"],
)
# No detail config - will fall back to read!
# Both list and retrieve use QuerySet.read optimizations
# generate_detail_s() returns same schema as generate_read_s()
Using is_for Parameter Directly
from ninja_aio.models import ModelUtil
util = ModelUtil(Article)
# For list operations
qs = await util.get_objects(request, is_for="read")
# For single object retrieval
obj = await util.get_object(request, pk=1, is_for="detail")
# For serialization
data = await util.read_s(schema, request, instance=obj, is_for="detail")
items = await util.list_read_s(schema, request, instances=qs, is_for="read")
🔍 Migration Guide
Breaking Change: is_for_read → is_for
If you call ModelUtil methods directly with is_for_read, update to use is_for:
# Before (v2.8.0)
await util.get_objects(request, is_for_read=True)
await util.get_object(request, pk=1, is_for_read=True)
await util.read_s(schema, request, instance=obj, is_for_read=True)
# After (v2.9.0)
await util.get_objects(request, is_for="read")
await util.get_object(request, pk=1, is_for="detail")
await util.read_s(schema, request, instance=obj, is_for="detail")
Mapping:
| Old Parameter | New Parameter |
|---------------|---------------|
| is_for_read=True | is_for="read" (for list) or is_for="detail" (for retrieve) |
| is_for_read=False | is_for=None |
Adding Detail-Specific Optimizations
# Before (v2.8.0) - Same optimizations for list and retrieve
class QuerySet:
read = ModelQuerySetSchema(
select_related=["author"],
prefetch_related=["tags", "comments"], # Always loaded!
)
# After (v2.9.0) - Different optimizations per operation
class QuerySet:
read = ModelQuerySetSchema(
select_related=["author"],
prefetch_related=[], # Light for list
)
detail = ModelQuerySetSchema(
select_related=["author", "author__profile"],
prefetch_related=["tags", "comments"], # Full for retrieve
)
📊 Performance Benefits
| Scenario | Without Detail Config | With Detail Config |
|---|---|---|
| List 100 articles | Prefetches tags + comments for all | Only prefetches what's needed for list |
| Retrieve single | Uses list optimizations | Uses detail-specific optimizations |
| N+1 queries | May occur if list over-fetches | Optimized per endpoint |
| Memory usage | Higher (unnecessary prefetch) | Optimized per operation |
⚠️ Important Notes
- Breaking Change:
is_for_read: boolparameter renamed tois_for: Literal["read", "detail"] | None - Fallback Behavior: All fallbacks are automatic - no configuration needed for backward compatibility
- QuerySet.detail: Optional - falls back to
QuerySet.readif not defined - DetailSerializer fields: Optional - falls back to
ReadSerializerfields if not defined - generate_detail_s(): Now always returns a schema (falls back to read schema)

)
]
🔍 Migration Guide
Using Detail Schemas
No migration required! Detail schema support is fully backward compatible:
# Existing code continues to work (no DetailSerializer = uses schema_out for retrieve)
class Article(ModelSerializer):
class ReadSerializer:
fields = ["id", "title", "content"] # Used for both list AND retrieve
# New: Add DetailSerializer for different retrieve response
class Article(ModelSerializer):
class ReadSerializer:
fields = ["id", "title"] # Used for list only
class DetailSerializer:
fields = ["id", "title", "content", "author", "tags"] # Used for retrieve
Using serializer_class in M2MRelationSchema
# Before (v2.7.0) - Must provide related_schema manually
M2MRelationSchema(
model=Tag,
related_name="tags",
related_schema=TagOut, # Must define this schema manually
)
# After (v2.8.0) - Can use serializer_class instead
M2MRelationSchema(
model=Tag,
related_name="tags",
serializer_class=TagSerializer, # Auto-generates related_schema!
)
Updating Custom ViewSet Subclasses
If you override get_schemas(), update to return 4-tuple:
# Before (v2.7.0)
def get_schemas(self):
return (schema_out, schema_in, schema_update)
# After (v2.8.0)
def get_schemas(self):
return (schema_out, schema_detail, schema_in, schema_update)
🎯 When to Use Detail Schema
- Performance Optimization: Return minimal fields in list views, full details in retrieve
- API Design: Clients get summaries in lists, full objects on individual requests
- Expensive Relations: Avoid loading M2M/reverse relations for list endpoints
- Computed Fields: Only compute expensive fields for single object retrieval
- Bandwidth Optimization: Reduce payload size for list responses
📊 Performance Benefits
| Scenario | Without Detail Schema | With Detail Schema |
|---|---|---|
| List 100 articles | Returns 100 × full content | Returns 100 × summary only |
| Load M2M tags | Loaded for all 100 items | Only loaded for single retrieve |
| Computed fields | Calculated for all items | Only calculated on retrieve |
| Response size | Large (full content) | Optimized per endpoint |
⚠️ Important Notes
- Fallback Behavior: If
DetailSerializer/schema_detailnot defined, retrieve usesschema_out - Schema Generation:
generate_detail_s()returnsNoneif no detail config exists - Backward Compatibility: All existing code works without changes
- 4-Tuple Return:
get_schemas()now returns 4 values instead of 3 - M2M Validation: Cannot use
serializer_classwithModelSerializermodels
🙏 Acknowledgments
This release focuses on:
- Enhanced API design flexibility with separate list/detail schemas
- Performance optimization for list endpoints
- Better M2M relation configuration options
- Improved code organization and maintainability

📦 Quick Start with Detail Schema
from ninja_aio.models import ModelSerializer
from ninja_aio.views import APIViewSet
from ninja_aio import NinjaAIO
from django.db import models
api = NinjaAIO(title="My API")
# Step 1: Define your model with ReadSerializer and DetailSerializer
class Article(ModelSerializer):
title = models.CharField(max_length=200)
summary = models.TextField()
content = models.TextField()
author = models.ForeignKey(User, on_delete=models.CASCADE)
tags = models.ManyToManyField(Tag)
class ReadSerializer:
fields = ["id", "title", "summary"] # Minimal for list
class DetailSerializer:
fields = ["id", "title", "summary", "content", "author", "tags"] # Full for retrieve
# Step 2: Create your ViewSet (schemas auto-generated!)
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
pass
# That's it! Your API now has optimized list and detail endpoints:
# GET /articles/ → Returns list with minimal fields
# GET /articles/{pk} → Returns single article with all fields

Union["myapp.serializers.SerializerA", SerializerB] - Lazy resolution of union members supports forward/circular dependencies
-
Schema generator creates union of all possible schemas automatically
-
Absolute Import Path Support for String References:
- String references now support absolute import paths using dot notation
- Example:
"myapp.serializers.UserSerializer"or"users.serializers.UserSerializer" - Enables cross-module serializer references without circular import issues
- Automatic module importing when needed (uses
importlib.import_module()) - Resolves lazily when schemas are generated
- Works seamlessly with Union types
🛠 Changed
- Enhanced Serializer Reference Resolution:
- Now handles Union types by recursively resolving each member
- Handles ForwardRef objects created by string type hints in unions (e.g.,
Union["StringType"]) -
Optimizes single-type unions by returning the single type directly
-
Enhanced Relation Schema Generation:
- Generates union schemas when serializer reference is a Union type
- Maintains full backward compatibility with single serializer references
-
Automatically filters out None schemas from union members
-
Updated Type Hints:
- All serializer methods updated to reflect Union support
- Better type safety for Union[Schema, ...] return values
- Clearer documentation of acceptable input types

- Better error messages with full import paths in exceptions
🚀 Use Cases & Examples
Basic Polymorphic Relations
from typing import Union
from ninja_aio.models import serializers
class VideoSerializer(serializers.Serializer):
class Meta:
model = models.Video
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "duration", "url"]
)
class ImageSerializer(serializers.Serializer):
class Meta:
model = models.Image
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "width", "height", "url"]
)
class CommentSerializer(serializers.Serializer):
class Meta:
model = models.Comment
schema_out = serializers.SchemaModelConfig(
fields=["id", "text", "content_object"]
)
relations_serializers = {
"content_object": Union[VideoSerializer, ImageSerializer],
}
Cross-Module References
# myapp/serializers.py
class ArticleSerializer(serializers.Serializer):
class Meta:
model = models.Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "author"]
)
relations_serializers = {
"author": "users.serializers.UserSerializer", # Absolute path
}
# users/serializers.py
class UserSerializer(serializers.Serializer):
class Meta:
model = models.User
schema_out = serializers.SchemaModelConfig(
fields=["id", "username", "articles"]
)
relations_serializers = {
"articles": "myapp.serializers.ArticleSerializer", # Circular ref!
}
Generic Foreign Keys
from django.contrib.contenttypes.fields import GenericForeignKey
from typing import Union
class CommentSerializer(serializers.Serializer):
class Meta:
model = Comment
schema_out = serializers.SchemaModelConfig(
fields=["id", "text", "created_at", "content_object"]
)
relations_serializers = {
"content_object": Union[
BlogPostSerializer,
ProductSerializer,
EventSerializer
],
}
🔍 Migration Guide
Using Union Types
No migration needed! Union support is fully backward compatible:
# Existing code continues to work
class MySerializer(serializers.Serializer):
class Meta:
model = MyModel
relations_serializers = {
"author": AuthorSerializer, # ✅ Still works
}
# New Union syntax available
class MySerializer(serializers.Serializer):
class Meta:
model = MyModel
relations_serializers = {
"content": Union[VideoSerializer, ImageSerializer], # ✅ New!
}
Using Absolute Import Paths
Update string references to use absolute paths for cross-module references:
# Before (v2.6.1) - Only local references worked
relations_serializers = {
"author": "AuthorSerializer", # Must be in same module
}
# After (v2.7.0) - Absolute paths supported
relations_serializers = {
"author": "users.serializers.AuthorSerializer", # ✅ Cross-module!
}
String Reference Formats
Both formats are supported:
relations_serializers = {
# Local reference (same module)
"field1": "LocalSerializer",
# Absolute import path (any module)
"field2": "myapp.serializers.RemoteSerializer",
# Union with mixed formats
"field3": Union["LocalSerializer", "myapp.other.RemoteSerializer"],
}
🎯 When to Use Union Types
- Polymorphic Relations: Generic foreign keys, Django ContentType relations
- Flexible APIs: Different response formats based on runtime type
- Gradual Migrations: Transitioning between serializer implementations
- Multi-Tenant Systems: Different serialization per tenant
- Dynamic Content: CMS systems with multiple content types
- Activity Feeds: Mixed content types in single endpoint
📊 Performance Notes
- Lazy Resolution: Union members resolved only when schemas generated (no startup overhead)
- Schema Caching: Generated schemas can be cached for better performance
- Memory Efficient: Only generates schemas for types actually used
- Import Optimization: Absolute paths only import modules when needed
⚠️ Important Notes
- String References: Resolve within same module by default; use absolute paths for cross-module
- Union Schema Generation: Creates union of all possible schemas from union members
- Backward Compatibility: All existing code continues to work without changes
- Python Version: Requires Python 3.10+ (Union syntax compatibility)
- Type Validation: Union types provide type hints but runtime validation depends on your model logic
🙏 Acknowledgments
This release focuses on:
- Enhanced flexibility for polymorphic relationships
- Better support for complex project architectures
- Improved developer experience with cross-module references
- Python 3.10+ compatibility and modern typing features

📦 Quick Start with Union Types
from typing import Union
from ninja_aio.models import serializers
# Step 1: Define your serializers
class VideoSerializer(serializers.Serializer):
class Meta:
model = Video
schema_out = serializers.SchemaModelConfig(fields=["id", "title", "url"])
class ImageSerializer(serializers.Serializer):
class Meta:
model = Image
schema_out = serializers.SchemaModelConfig(fields=["id", "title", "url"])
# Step 2: Use Union in relations_serializers
class CommentSerializer(serializers.Serializer):
class Meta:
model = Comment
schema_out = serializers.SchemaModelConfig(
fields=["id", "text", "content_object"]
)
relations_serializers = {
"content_object": Union[VideoSerializer, ImageSerializer],
}
# Step 3: Use with APIViewSet (automatic!)
@api.viewset(model=Comment)
class CommentViewSet(APIViewSet):
serializer_class = CommentSerializer
# Union types work automatically!
Version History
For older versions, please refer to the GitHub releases page.
v2.6.1
Jan 12, 2026✨ Added
- String Reference Support for Relations:
relations_serializersnow accepts string references (e.g.,"ArticleSerializer") in addition to class references- Enables forward references and circular dependencies between serializers
-
Lazy resolution of serializer references when schemas are generated
-
New Internal Methods:
BaseSerializer._resolve_serializer_reference()- Resolves string or class serializer referencesBaseSerializer._resolve_relation_schema()- Centralized relation schema resolution logic
🛠 Changed
- Schema Generation Lifecycle:
- Removed eager schema generation from
Serializer.__init_subclass__() - Schemas are now generated on-demand via explicit calls to
generate_*()methods - Removed cached schema properties (
.schema_in,.schema_out,.schema_update,.schema_related) -
Breaking: Must use
generate_create_s(),generate_read_s(), etc. instead of accessing properties -
Internal Refactoring:
- Replaced
match/casewithif/elifstatements in_generate_model_schema()for better readability - Added configuration mapping dictionaries (
_SERIALIZER_CONFIG_MAP) to simplify lookups - Consolidated duplicate schema resolution logic in relation handling methods
-
Improved code organization with clearer comments and structure
-
APIViewSet Integration:
- Added
serializerinstance property initialized fromserializer_class() - Better integration with on-demand schema generation
📝 Documentation
- Updated Serializer Documentation:
- Added "String References for Forward/Circular Dependencies" section with examples
- Updated "Schema Generation" section to clarify on-demand generation
- Removed outdated references to eager schema generation
- Updated comparison table: "Auto-binding" → "Schema generation"
-
Enhanced configuration section with bold formatting and clearer descriptions
-
Key Documentation Changes:
- Emphasized that
generate_*()methods must be called explicitly - Documented string reference requirements (same module, lazy resolution)
- Added circular dependency example with
AuthorSerializer↔ArticleSerializer
⚠ Breaking Changes & Migration Notes
Removed Schema Properties
Schema properties have been removed from Serializer class. You must now explicitly call generation methods:
# Before (v2.5.0) - NO LONGER WORKS
ArticleSerializer.schema_in # ❌ AttributeError
ArticleSerializer.schema_out # ❌ AttributeError
ArticleSerializer.schema_update # ❌ AttributeError
ArticleSerializer.schema_related # ❌ AttributeError
# After (v2.6.0) - Explicit generation required
ArticleSerializer.generate_create_s() # ✅ Returns create schema
ArticleSerializer.generate_read_s() # ✅ Returns read schema
ArticleSerializer.generate_update_s() # ✅ Returns update schema
ArticleSerializer.generate_related_s() # ✅ Returns related schema
Note: This change typically doesn't affect user code since these methods are called internally by APIViewSet. Only relevant if you're calling these methods directly.
🔍 Migration Guide
1. Update Schema Access in Custom Code
If you're directly accessing schema properties, update to use generation methods:
# Before (v2.5.0)
class ArticleViewSet(APIViewSet):
def get_schemas(self):
return {
"in": self.serializer_class.schema_in, # ❌ No longer works
"out": self.serializer_class.schema_out, # ❌ No longer works
}
# After (v2.6.0)
class ArticleViewSet(APIViewSet):
def get_schemas(self):
return {
"in": self.serializer_class.generate_create_s(), # ✅ Explicit generation
"out": self.serializer_class.generate_read_s(), # ✅ Explicit generation
}
2. Use String References for Circular Dependencies
Take advantage of string references to simplify circular dependencies:
# Before (v2.5.0) - Workarounds needed for circular refs
class AuthorSerializer(serializers.Serializer):
class Meta:
model = models.Author
schema_out = serializers.SchemaModelConfig(
fields=["id", "name", "articles"]
)
# Had to carefully order class definitions or use late binding
# After (v2.6.0) - String references make it easy
class AuthorSerializer(serializers.Serializer):
class Meta:
model = models.Author
schema_out = serializers.SchemaModelConfig(
fields=["id", "name", "articles"]
)
relations_serializers = {
"articles": "ArticleSerializer", # ✅ Forward reference
}
class ArticleSerializer(serializers.Serializer):
class Meta:
model = models.Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "author"]
)
relations_serializers = {
"author": "AuthorSerializer", # ✅ Circular reference works!
}
String Reference Requirements:
- Must be the exact class name as a string
- Serializer must be defined in the same module
- Resolution happens lazily when generate_*() is called
- Both forward and circular references are supported
3. Schema Generation Best Practices
In APIViewSet (no changes needed):
# APIViewSet handles schema generation automatically
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
serializer_class = ArticleSerializer
# No changes needed - works automatically
In Custom Code (call generate methods):
# Explicit schema generation when needed
from ninja import Router
router = Router()
@router.post("/articles/", response=ArticleSerializer.generate_read_s())
async def create_article(request, payload: ArticleSerializer.generate_create_s()):
serializer = ArticleSerializer()
instance = await serializer.create(payload.model_dump())
return await serializer.model_dump(instance)
Caching Schemas (if needed for performance):
# Cache schemas at module level if generating repeatedly
ARTICLE_CREATE_SCHEMA = ArticleSerializer.generate_create_s()
ARTICLE_READ_SCHEMA = ArticleSerializer.generate_read_s()
@router.post("/articles/", response=ARTICLE_READ_SCHEMA)
async def create_article(payload: ARTICLE_CREATE_SCHEMA):
# Use cached schemas
pass
4. Complete Migration Example
Here's a complete before/after example:
# Before (v2.5.0)
from ninja_aio.models import serializers
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
class AuthorSerializer(serializers.Serializer):
class Meta:
model = models.Author
schema_out = serializers.SchemaModelConfig(
fields=["id", "name"]
)
class ArticleSerializer(serializers.Serializer):
class Meta:
model = models.Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "author"]
)
relations_serializers = {
"author": AuthorSerializer, # Required class ordering
}
# Access schemas (no longer works)
create_schema = ArticleSerializer.schema_in # ❌
read_schema = ArticleSerializer.schema_out # ❌
# After (v2.6.0)
from ninja_aio.models import serializers
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
class AuthorSerializer(serializers.Serializer):
class Meta:
model = models.Author
schema_out = serializers.SchemaModelConfig(
fields=["id", "name", "articles"]
)
relations_serializers = {
"articles": "ArticleSerializer", # ✅ String reference
}
class ArticleSerializer(serializers.Serializer):
class Meta:
model = models.Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "author"]
)
relations_serializers = {
"author": "AuthorSerializer", # ✅ Circular reference!
}
# Explicit schema generation
create_schema = ArticleSerializer.generate_create_s() # ✅
read_schema = ArticleSerializer.generate_read_s() # ✅
# Using with APIViewSet (no changes needed)
api = NinjaAIO()
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
serializer_class = ArticleSerializer
# Automatically works with on-demand generation
🐛 Bug Fixes
- Fixed lazy resolution issues with forward and circular serializer references
- Improved error messages when string references cannot be resolved
- Corrected
model_dump()andmodels_dump()to use explicit schema generation - Fixed potential issues with
model_utilvsutilattribute naming
🚀 Performance Improvements
- Reduced Initialization Overhead: Schemas only generated when actually needed
- Memory Efficiency: Unused schemas are never created
- Lazy Resolution: String references resolved on-demand, reducing startup time
- Faster Imports: Removed eager schema generation from module import time
📊 Code Quality Improvements
- Reduced Code Duplication:
- Extracted common relation resolution logic into
_resolve_relation_schema() - Consolidated duplicate code in
_build_schema_reverse_rel()and_build_schema_forward_rel() -
Reduced relation handling code by ~40 lines
-
Improved Maintainability:
- Replaced
match/casewith clearerif/elifstatements - Added configuration mapping dictionaries for cleaner lookups
- Better code organization with descriptive comments
-
Consistent use of
any()for empty checks -
Better Readability:
- Flattened nesting in
_generate_model_schema() - Clearer separation between special cases and standard logic
- Improved docstrings and parameter descriptions
- More descriptive variable names
🙏 Acknowledgments
This release focuses on:
- Architectural improvements for forward/circular dependency support
- Cleaner, more maintainable internal code structure
- On-demand resource generation for better performance
- Enhanced developer experience with string references
📝 Notes
-
Schema Generation: While properties were removed,
APIViewSetautomatically callsgenerate_*()methods, so most applications won't need code changes -
Performance: On-demand generation typically improves startup time. If you need schemas multiple times, consider caching them at module level
-
String References: Only resolve within the same module. For cross-module references, use direct class imports
-
Backward Compatibility: Code using
APIViewSetcontinues to work without changes. Direct schema property access will raiseAttributeError -
Internal Refactoring: This release includes significant internal refactoring for code quality without changing public APIs (except removal of schema properties)

⚠ Breaking Changes & Migration Notes
Transaction Behavior (New Default)
Create, update, and delete operations are now automatically wrapped in database transactions:
# Automatic transaction wrapping (new in v2.5.0)
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
pass # create/update/delete wrapped in @aatomic
Migration: If you were manually managing transactions in lifecycle hooks, you may encounter nested transaction issues. Remove manual transaction management:
# Before (v2.4.0)
async def post_create(self, instance):
async with transaction.atomic(): # Remove this
await AuditLog.objects.acreate(...)
# After (v2.5.0)
async def post_create(self, instance):
# Transaction already managed by @aatomic
await AuditLog.objects.acreate(...)
Serializer Hook Signatures
Added Serializer hooks signatures, they are standardized to always receive instance:
# v2.5.0 - Standardized (always receive instance)
class MySerializer(Serializer):
async def custom_actions(self, payload, instance):
# instance parameter required
pass
async def post_create(self, instance):
# instance parameter required
pass
def before_save(self, instance):
# instance parameter required
pass
def after_save(self, instance):
# instance parameter required
pass
def on_delete(self, instance):
# instance parameter required
pass
🔍 Migration Guide
1. Updating Serializer Lifecycle Hooks
If you're using Serializer (Meta-driven pattern), update hook signatures to receive instance parameter:
from ninja_aio.models import serializers
from asgiref.sync import sync_to_async
class ArticleSerializer(serializers.Serializer):
class Meta:
model = Article
schema_in = serializers.SchemaModelConfig(
fields=["title", "content", "author"],
customs=[("send_notification", bool, True)]
)
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "content", "author", "created_at"]
)
# Async hooks - receive instance parameter
async def custom_actions(self, payload, instance):
"""Execute custom logic after field assignment."""
if payload.get("send_notification"):
# Access instance fields
await send_email(
instance.author.email,
f"Article created: {instance.title}"
)
async def post_create(self, instance):
"""Hook after first save (creation only)."""
await AuditLog.objects.acreate(
action="article_created",
article_id=instance.id,
user_id=instance.author_id
)
# Sync hooks - also receive instance parameter
def before_save(self, instance):
"""Modify instance before save."""
from django.utils.text import slugify
if not instance.slug:
instance.slug = slugify(instance.title)
def after_save(self, instance):
"""Execute logic after save."""
# Clear cache
from django.core.cache import cache
cache.delete(f"article:{instance.id}")
def on_create_before_save(self, instance):
"""Before save, creation only."""
instance.view_count = 0
def on_create_after_save(self, instance):
"""After save, creation only."""
# Log creation
import logging
logger = logging.getLogger(__name__)
logger.info(f"Article {instance.id} created")
def on_delete(self, instance):
"""After deletion."""
import logging
logger = logging.getLogger(__name__)
logger.info(f"Article {instance.id} deleted")
Key Points:
- All hooks receive instance as a parameter
- Async hooks: custom_actions(payload, instance), post_create(instance)
- Sync hooks: before_save(instance), after_save(instance), on_delete(instance)
- Creation-specific hooks: on_create_before_save(instance), on_create_after_save(instance)
2. Configuring QuerySet Optimization
Add QuerySet configuration to your Serializer or ModelSerializer for automatic query optimization:
from ninja_aio.models import serializers
from ninja_aio.schemas.helpers import ModelQuerySetSchema, ModelQuerySetExtraSchema
class ArticleSerializer(serializers.Serializer):
class Meta:
model = Article
schema_out = serializers.SchemaModelConfig(
fields=["id", "title", "content", "author", "category", "tags"]
)
relations_serializers = {
"author": AuthorSerializer,
"category": CategorySerializer,
"tags": TagSerializer,
}
class QuerySet:
# Applied to list and retrieve operations
read = ModelQuerySetSchema(
select_related=["author", "category"],
prefetch_related=["tags"],
)
# Applied when queryset_request hook is called
queryset_request = ModelQuerySetSchema(
select_related=["author__profile"],
prefetch_related=["comments", "comments__author"],
)
# Named scopes for specific use cases
extras = [
ModelQuerySetExtraSchema(
scope="detail_view",
select_related=["author", "author__profile", "category"],
prefetch_related=["tags", "comments", "comments__author"],
),
ModelQuerySetExtraSchema(
scope="list_view",
select_related=["author", "category"],
prefetch_related=["tags"],
),
]
@classmethod
async def queryset_request(cls, request):
"""
Optional: Customize queryset based on request.
Automatically enhanced with QuerySet.queryset_request optimizations.
"""
qs = cls._meta.model.objects.all()
# Filter based on user permissions
if not request.user.is_staff:
qs = qs.filter(is_published=True)
# Add request-specific filters
if request.GET.get("featured"):
qs = qs.filter(is_featured=True)
return qs
For ModelSerializer:
from ninja_aio.models import ModelSerializer
from ninja_aio.schemas.helpers import ModelQuerySetSchema
from django.db import models
class Article(ModelSerializer):
title = models.CharField(max_length=200)
content = models.TextField()
author = models.ForeignKey(User, on_delete=models.CASCADE)
category = models.ForeignKey(Category, on_delete=models.SET_NULL, null=True)
tags = models.ManyToManyField(Tag, related_name="articles")
class ReadSerializer:
fields = ["id", "title", "content", "author", "category", "tags"]
class QuerySet:
read = ModelQuerySetSchema(
select_related=["author", "category"],
prefetch_related=["tags"],
)
queryset_request = ModelQuerySetSchema(
select_related=["author__profile"],
prefetch_related=["comments"],
)
@classmethod
async def queryset_request(cls, request):
"""Optimize queries for this model."""
return cls.objects.select_related("author", "category")
How QuerySet Configuration Works:
read: Applied automatically to list and retrieve operations whenis_for_read=Truequeryset_request: Applied whenwith_qs_request=True(default) inget_objects()orget_object()extras: Named scopes accessible viaQueryUtil.SCOPESfor custom scenarios- Merging: Optimizations from multiple sources are merged (no duplicates)
Benefits:
- Eliminates N+1 queries automatically
- Centralizes query optimization configuration
- Works with both ModelSerializer and Serializer patterns
- Optimizations apply to all CRUD operations
3. Customizing Model Display Names
Override verbose names without modifying models:
@api.viewset(model=Article)
class ArticleViewSet(APIViewSet):
model_verbose_name = "Blog Post"
model_verbose_name_plural = "Blog Posts"
# OpenAPI will use "Blog Post" instead of "Article"
🐛 Bug Fixes
- Fixed query optimization merging when both model and serializer provide hints
- Corrected
read_s()behavior when bothinstanceandquery_dataprovided (now raises clear error) - Improved error messages for missing primary key in
get_object() - Fixed duplicate route registration with
@unique_viewdecorator
🚀 Performance Improvements
- Transaction management with
@aatomicreduces database round-trips - Query optimization merging eliminates redundant select_related/prefetch_related
with_qs_requestparameter allows skipping hook when not needed
🙏 Acknowledgments
This release focuses on:
- Enhanced transaction safety
- Flexible query control
- Per-operation customization
- Comprehensive documentation
📝 Notes
-
Backward Compatibility: All v2.4.0 code continues to work. New parameters have sensible defaults.
-
Transaction Overhead: The
@aatomicdecorator adds minimal overhead. If you need non-transactional operations, override the view methods directly. -
Query Parameters:
with_qs_requestdefaults toTrueto maintain v2.4.0 behavior. Set toFalseto skip the queryset_request hook. -
Serializer Hooks: If migrating from v2.4.0 Serializer usage, ensure all hooks accept the
instanceparameter.

v2.4.0
Jan 09, 2026✨ Added
- Serializer (Meta-driven):
- New Serializer for vanilla Django models configured via nested Meta (no ModelSerializer inheritance).
- Dynamic schema generation helpers: generate_read_s, generate_create_s, generate_update_s, generate_related_s.
- Relation handling via relations_serializers for forward and reverse relations.
- APIViewSet:
- serializer_class to auto-generate missing schemas for non-ModelSerializer models and drive queryset_request.
- ModelUtil:
- Accepts serializer_class to build querysets using Serializer.queryset_request when provided.
- Docs/README:
- New docs page: api/models/serializers.md with usage and examples.
- README sections/examples for Meta-driven Serializer.
- MkDocs nav entry for Serializer.
- Tests:
- Serializer tests (forward and reverse relations).
- Viewset tests using serializer_class-backed endpoints.
🛠 Changed
- Package layout:
- ninja_aio/models/init.py now exports ModelUtil and ModelSerializer.
- models.py refactored to models/utils.py; ModelSerializer moved to models/serializers.py.
- API internals:
- APIViewSet.compute_schema generates schemas from serializer_class for vanilla models; retains model-backed generation for ModelSerializer.
- ModelUtil.get_queryset_request uses serializer_class when provided.
- Docs:
- Index formatting tweaks; added links and examples for Serializer docs.
📝 Documentation
- Serializer (Meta-driven):
- Configure via Meta: model, schema_in, schema_out, schema_update, relations_serializers.
- Examples for FK and reverse relations; customs and optionals.
- APIViewSet:
- Using serializer_class to auto-generate schemas and plug into queryset_request.
- README:
- Quick example attaching Serializer to APIViewSet.
- MkDocs:
- Added nav entry under Models: Serializer (Meta-driven).
⚠ Notes / Potential Impact
- Relation serializers:
- Reverse relations on vanilla models need relations_serializers entries to include nested schemas; otherwise skipped unless the related model is a ModelSerializer.
- A UserWarning is emitted when a reverse relation is listed without a mapping; suppressed in tests via NINJA_AIO_TESTING=True.
- Refactor:
- Imports may need updates due to ModelUtil relocation and new serializers module.

- Define a Meta-driven Serializer for existing Django models and attach it to APIViewSet via serializer_class.
- Provide relations_serializers for reverse relations to include nested schemas on read.
- Update imports:
- from ninja_aio.models import ModelUtil, ModelSerializer
- from ninja_aio.models.serializers import Serializer, SchemaModelConfig - If relying on queryset_request with vanilla models, implement Serializer.queryset_request; APIViewSet and ModelUtil will use it automatically.
v2.3.2
Jan 08, 2026✨ Added
- Support Url pydantic field serialization
- Support for django ninja until 1.6
v2.3.1
Jan 07, 2026✨ Added
- CI/Docs Deployment:
- GitHub workflow updated to recognize and manage version "2.3" for docs deploy/delete.
- Documentation/README:
- Added link to the external example repository: https://github.com/caspel26/ninja-aio-blog-example.
🛠 Changed
- README/Docs:
- Switched examples to decorator-first style with
@api.viewset(Model)and in-class method decorators (e.g.,@api_post). - Removed explicit
api = apiandmodel = ...from examples where@api.viewset(...)is used; emphasized automatic registration. - Cleaned and reformatted examples and quick links table; clarified usage in the index page and decorators page.
- Packaging:
- Python version spec adjusted from
>=3.10, <=3.14to>=3.10, <3.15in pyproject metadata.
🗑 Removed
- In-repo example apps:
- Deleted
examples/ex_1andexamples/ex_2(models, views, urls, and auth). Examples are now hosted in the external repository linked in the README.
📝 Documentation
- Index and README updated to prefer
@api.viewset(Model)and decorator-based custom endpoints. - Decorators page (
docs/api/views/decorators.md) revised to reflect decorator-first usage. - Added references to the external example repository for complete, runnable samples.
v2.3.0
Jan 04, 2026✨ Added
- Decorators:
- New operation decorators for class methods:
api_get,api_post,api_put,api_patch,api_delete,api_options,api_head(import fromninja_aio.decorators). - Utilities:
decorate_view,aatomic,unique_view(now underninja_aio.decorators). - Factory-backed decorators ensure clean OpenAPI signatures (exclude
self) and support extra decorators like pagination. - Views:
- APIView/APIViewSet auto-register decorated methods via lazy binding; no manual
add_views_to_route()when using@api.view/@api.viewset. - APIViewSet supports global trailing slash setting via
settings.NINJA_AIO_APPEND_SLASH(default True). - M2M:
M2MRelationSchema.append_slashto control trailing slash on the GET relation route.- Relation path normalization for consistent URLs whether
pathincludes leading slash or not. - Tests/Examples:
- Added decorator-based examples and tests for custom endpoints on views and viewsets.
🛠 Changed
- README/Docs:
- Prefer
@api.viewset(Model)with decorator-based endpoints; legacyviews()remains supported. - Clarified trailing slash behavior for CRUD retrieve paths and M2M relations.
- Decorator-first examples across APIView and APIViewSet pages; cleaner OpenAPI notes.
- API internals:
- Base API class now binds decorator-registered methods via
_add_views(); APIView/APIViewSet callsuper()._add_views()before legacyviews(). - APIViewSet path generation respects
NINJA_AIO_APPEND_SLASHfor retrieve path (/{pk}/vs/{pk}). - Exceptions/Helpers:
- Added docstrings for clearer behavior in exceptions, query helpers, and schemas.
📝 Documentation
- APIView/APIViewSet:
- Decorator-first usage with examples; automatic lazy registration; signature preservation.
- Decorators:
- Using operation decorators with extra decorators (e.g.,
paginate(PageNumberPagination),unique_view(name)). - ViewSet relations:
- Per-relation
append_slash; path normalization rules; trailing slash settings. - README:
- Simplified setup:
@api.viewset(Model)and decorator-based custom endpoints.
⚠ Notes / Potential Impact
- Trailing slash:
- Global
NINJA_AIO_APPEND_SLASHdefaults to True. Disable to remove trailing slash from retrieve paths. - M2M GET relation endpoints default to no trailing slash; enable per relation with
append_slash=True. - Registration:
- When using
@api.view/@api.viewset, endpoints defined via decorators are mounted automatically; avoid redundant manual registration. - OpenAPI:
- Decorator-backed handlers exclude
selfand preserve type hints for cleaner specs.
🔍 Migration / Action
- Adopt decorators for extra endpoints:
- APIView: annotate the class with@api.view(...), then decorate methods with@api_get("/path", ...).
- APIViewSet: annotate with@api.viewset(Model, ...), then use@api_get("/path", ...),@api_post(...), etc. - Trailing slash configuration:
- SetNINJA_AIO_APPEND_SLASH=Falsein Django settings to drop trailing slash on retrieve paths globally.
- For M2M GET relations, useM2MRelationSchema(append_slash=True/False)to control trailing slash. - Legacy support:
-views()continues to work; prefer decorators for clearer code and better OpenAPI. - Docs/examples:
- Update references to new decorator modules and follow decorator-first examples.
v2.2.0
Jan 03, 2026✨ Added
- API:
- Decorators:
NinjaAIO.view(prefix, tags)andNinjaAIO.viewset(model, prefix, tags)for automatic registration. - Base API class: shared attributes for APIView and APIViewSet (api, router_tags, api_route_path).
- Views:
- APIView: supports constructor args
(api, prefix, tags)withrouter_tagsand standardizederror_codes. - APIViewSet: constructor
(api, model, prefix, tags); infers base path from model when not provided;router_tagssupport. - Auth:
- JwtKeys type expands to include
jwk.OctKey(HMAC). validate_keyacceptsjwk.OctKey.encode_jwt/decode_jwttype hints generalized toJwtKeys.- Tests:

api/views/mixins.md; MkDocs navigation adjusted.
⚠ Notes / Potential Impact
- Error handling:
- 428 code removed; rely on {400, 401, 404}.
- Auth configuration:
- Use lists for multiple auth methods; bitwise OR in docs deprecated.
- Docs deployment:
- Default alias set to “latest” on deploy when MAKE_LATEST=true.
- Python compatibility:
- Upper bound set to 3.14.
🔍 Migration / Action
- Adopt decorators:

- Extended test model with
age,active, andactive_fromfields. - Added viewset tests for mixins (icontains, boolean, numeric, date comparisons).
- Added auth tests for JWT encode/decode and AsyncJwtBearer claim validation.
- Docs navigation:
- Added Mixins page and JWT & AsyncJwtBearer page to MkDocs nav.
- MkDocs
mikeconfig setsdefault: latest.
🛠 Changed
- Docs workflow (
.github/workflows/docs.yml): - Safer deletion: requires explicit
delete_versionchoice anddelete_confirm, protectslatest,stable, and current default. make_latestdefault set to false.- Coverage workflow:
- Bump
codecov/codecov-actionfrom v5.5.1 to v5.5.2. - API helpers:
- Use
decorate_viewto composeunique_viewandpaginatefor related GET endpoints. - APIViewSet (imports and behavior):
- Module reorganized to
ninja_aio/views/api.pywith updated internal imports. get_schemas: generates schemas only if missing when model is aModelSerializerMeta, else returns explicitly set schemas.- Hook docs clarified to allow sync or async handlers for query params.
- Auth:
encode_jwt: header now includeskidonly when present (conditional merge).- Docs:
docs/api/views/api_view_set.mdupdated to document ReadOnlyViewSet and WriteOnlyViewSet.docs/mixins.mdaligned with implemented mixins and examples.
📝 Documentation
- New:
- JWT & AsyncJwtBearer guide with examples for settings and direct JWK usage.
- Updated:
- Mixins reference to match implemented classes and recommended query param types.
- APIViewSet docs extended with ReadOnly/WriteOnly usage.
⚠ Notes / Potential Impact
- Docs deployment:
- Deletion requires explicit confirmation and cannot remove protected aliases or current default.

🔍 Migration / Action
- Update imports:
-from ninja_aio.views import APIViewSet, ReadOnlyViewSet, WriteOnlyViewSet
-from ninja_aio.views import mixinsfor filter mixins. - For related list endpoints using custom decorators, consider adopting
decorate_viewfor consistent composition. - If using JWT:
- Optionally setJWT_PRIVATE_KEY,JWT_PUBLIC_KEY,JWT_ISSUER,JWT_AUDIENCEin Django settings.
- Validate claims viaAsyncJwtBearer.claimsregistry and verify allowed algorithms. - Review docs workflow inputs before deleting versions; use
delete_confirm: true.

🔴 Breaking Changes
- Path PK schema type:
- PK type is inferred from the model PK. Code relying on
int | strin path schemas may need adjustments. - ManyToMany GET response shape:
- Response changed from a plain list to
{items: [...], count: N}. Clients must adapt parsing. - Import paths:
- Schema helpers moved under

[v2.0.0-rc3] - 2025-12-12
[2.0.0-rc3] - 2025-12-12
✨ Added
- ManyToManyAPI:
- New per-relation POST object resolution handler:
<related_name>_query_handler(self, request, pk, instance)returning a queryset, resolved via.afirst(). - Endpoint registration details documented: GET without trailing slash, POST with trailing slash; operationId conventions (
get_{base}_{rel},manage_{base}_{rel}).
🛠 Changed
- ManyToManyAPI:
- Split handlers: GET uses
<related_name>_query_params_handler(self, queryset, filters_dict); POST uses<related_name>_query_handler(...)for per-PK validation. - Manage view uses
_collect_m2m(...)with additional context (related_name,instance) and falls back toModelUtil.get_objects(...)when query handler is absent. - Improved docs and docstrings for concurrency, error semantics, and request/response payloads.
- Docs:
- Refined M2M section: clarified handlers, paths, operationIds, request bodies, and concurrency.
- Minor wording and formatting improvements; standardized examples.
- Version:
- Bump to
2.0.0-rc3.
📝 Documentation
- APIViewSet M2M docs updated:
- Clarified GET filters vs POST per-PK resolution.
- Documented response semantics and per-PK success/error messages.
- Added an example showcasing both handlers.
🔴 Breaking Changes
- Handler naming:
- GET filters must use
<related_name>_query_params_handler; POST add/remove resolution must use<related_name>_query_handler. Existing single-handler implementations should be split accordingly. - Endpoint paths:
- GET relation:
/{base}/{pk}/{rel_path}(no trailing slash). - POST relation:
/{base}/{pk}/{rel_path}/(trailing slash).
⚠ Notes / Potential Impact
| Area | Observation | Impact |
|---|---|---|
| Validation | POST uses per-PK resolution handler when present; fallback uses ModelUtil.get_objects. |
Tighten access control and scoping per relation. |
| Concurrency | aadd and aremove run concurrently via asyncio.gather. |
Faster bulk mutations; ensure thread-safety of custom logic. |
🔍 Migration / Action
- Implement per-relation handlers:
- GET filters:def|async def <rel>_query_params_handler(self, qs, filters: dict) -> qs.
- POST resolution:async def <rel>_query_handler(self, request, pk, instance) -> queryset. - Verify clients and OpenAPI consumers against the documented endpoint paths and operationIds.
- Ensure manage responses are consumed as documented (
results,errorswithcountanddetails).
✅ Suggested Follow-Ups
- Add tests for:
- Presence/absence of
<related_name>_query_handlerfallback behavior. - Sync vs async GET filter handlers.
- Per-PK error and success detail aggregation.

v1.0.4
Nov 03, 2025✨ Added
ModelUtil._rewrite_nested_foreign_keys: reintroduced helper to rename nested FK keys from<field>to<field>_idinside nested dicts (currently invoked conditionally inparse_output_data).
🛠 Changed
ModelUtil._extract_field_objconverted to async; now usesagetattrfor safer async attribute access.ModelUtil.parse_output_data:- Awaits the new async
_extract_field_obj. - Fetches related instance first, then (conditionally) calls
_rewrite_nested_foreign_keyswhen the outer field is aForeignKey.
📝 Documentation
- Table in
docs/api/models/model_serializer.md(CreateSerializer attributes) reformatted: - Condensed multiline description for
customsinto a single line with semicolons. - Adjusted column widths / alignment for cleaner diff footprint.
⚠ Note / Potential Issue
| Area | Observation | Impact |
|---|---|---|
parse_output_data |
Result of _rewrite_nested_foreign_keys is assigned to local v but not reattached to payload (final output still sets payload[k] = rel_instance). |
FK key rewriting may be a no-op for consumers; behavior might not match intent. |
🔍 Migration / Action
- If you relied on the absence of FK key rewriting (1.0.3), verify whether the restored helper actually affects payloads (it likely does not yet).
- If rewriting is desired, ensure the transformed dict (or additional metadata) is surfaced in the serialized output or adjust logic accordingly.
✅ Suggested Follow-Ups
- Add a test asserting expected presence (or absence) of
<field>_idkeys in nested output. - Decide whether payload should expose both the related object and rewritten key map, or deprecate the helper again if not needed.
v1.0.3
Nov 03, 2025✨ Added
M2MRelationSchema: New optional fieldrelated_schemadocumented (auto-generated when using aModelSerializer).
🛠 Changed
- Documentation tables (CRUD, Core Attributes, Auth, M2M Endpoints, Hooks) reformatted for alignment & readability.
- Extra blank lines inserted to improve Markdown rendering clarity.
ModelUtil.parse_output_data: simplified nested relation handling (direct instance assignment).
🗑 Removed
ModelUtil._rewrite_nested_foreign_keyshelper.- Foreign key nested dict rewriting logic (
<field>→<field>_id) during output serialization.
📄 Documentation
- Added warning block describing support for plain Django
ModelinM2MRelationSchema.modeland mandatoryrelated_schemawhen used. - Added
related_schemabullet to M2M relation capabilities list. - Ensured file ends with a trailing newline.
⚠ Breaking Change
| Change | Impact |
|---|---|
| Removal of FK key rewriting in nested outputs | Clients expecting <nested_fk>_id keys must adjust parsing logic |
🔍 Migration Notes
- If consumers relied on
<nested_fk>_idkeys, add a post-serialization adapter to inject them, or reintroduce prior logic. - When declaring M2M relations with plain Django models, always provide
related_schema; omission now results in validation errors.
📌 Highlights
- Cleaner docs + explicit M2M plain model guidance.
- Leaner serialization path (less mutation, clearer intent).
🧪 Suggested Follow‑Ups
- Add regression test ensuring nested FK dicts are no longer rewritten.
- Consider exposing an optional flag to restore legacy FK key rewriting if demand appears.
v1.0.2
Nov 01, 2025✨ Added

M2MRelationSchema(autorelated_schemavia validator). - Refactored M2M integration in
APIViewSet(now usesManyToManyAPI). - New test suites: decorators, exceptions/API, renderer/parser, many-to-many API.
- Centralized literal for “not found” (
tests/generics/literals.py).
🛠 Changed
NotFoundError: error key now uses underscored verbose name.ORJSONRenderer: replaced nested mutation with recursivetransform.ModelUtil/ModelSerializer: added comprehensive docstrings, normalized custom field tuples, improved FK and nested output handling.- Removed inline M2M view logic from
APIViewSet. - Enriched model serializer docs (tables, normalization, error cases).
M2MRelationSchema: validation for related schema generation.
🧾 Documentation
- Major rewrite of
docs/api/models/model_serializer.md: normalization workflow, error cases, best practices, expanded examples. - Added Release Notes navigation in
mkdocs.yml. - Inline internal-use warning for
ManyToManyAPI. - Improved readability (spacing, tables, JSON formatting).
✅ Tests
- Coverage for:
- ORJSON transformations (bytes→base64, IP→string).
unique_viewname suffix logic.- Exception parsing and API defaults.
- M2M add/remove flows + duplicate/error handling.
- Updated NotFoundError key format.
- Reused shared literal for 404 assertions.
📦 Tooling
- Added
mkdocs-macros-plugin. - Automated release visualization (HTML tables, cards).
- Cleaner MkDocs theme (font configuration).
⚠ Impact
| Change | Potential Effect |
|---|---|
| Underscored error keys | Clients parsing old keys must adjust |
| Extracted M2M logic | Custom subclasses relying on internals must migrate |
| 2‑tuple customs now required | Missing values trigger validation errors |
🔍 Upgrade Notes
- Update error handling for new 404 key shape.
- Migrate any manual M2M endpoint wiring to
ManyToManyAPI. - Review custom field tuples—add defaults if optional behavior desired.
🧪 Follow‑Ups
- Tag release (
git tag -a vX.Y.Z -m "Release vX.Y.Z" && git push --tags). - Optionally add top-level
CHANGELOG.md. - Decide on public stability of
ManyToManyAPI(remove warning when ready).

(Author, "authors", "co-authors", [AdminAuth()])
]
m2m_add = True
m2m_remove = True

- define your query params fields in this way. They are applied on CRUD list endpoint and will be shown also into swagger.
# views.py
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
from .models import Foo
api = NinjaAIO()
class FooAPI(APIViewSet):
model = Foo
api = api
query_params = {"name": (str, None), "active": (bool, None)}
async def query_params_handler(self, queryset, filters):
return queryset.filter(**{k: v for k, v in filters.items() if v is not None})
FooAPI().add_views_to_route()
ModelUtil get object improvement
You can now give extra getters and filters attribute to make the object query!
And that's it! For more information check README

from ninja_aio.models import ModelSerializer
class Foo(ModelSerializer):
name = models.CharField(max_length=30)
bar = models.CharField(max_length=30, default="")
active = models.BooleanField(default=False)
class ReadSerializer:
excludes = ["bar"]
class CreateSerializer:
fields = ["name"]
optionals = [("bar", str), ("active", bool)]
class UpdateSerializer:
excludes = ["id", "name"]
optionals = [[("bar", str), ("active", bool)]
🚀 Exclude CRUD endpoints into Views
You are able to exclude every crud endpoint, except for the additional views added by yourself, defining "disbale" APIViewSet's attribute.
# views.py
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
from .models import Foo
api = NinjaAIO()
class FooAPI(APIViewSet):
model = Foo
api = api
disable = ["retrieve", "update"]

-
define your optional fields in this way.
# models.py
from django.db import models
from ninja_aio.models import ModelSerializer
class Foo(ModelSerializer):
name = models.CharField(max_length=30)
bar = models.CharField(max_length=30, default="")

Oct 09, 2024What's Changed
News:
- Vanilla Django Model automatic async CRUD support by @caspel26.
Full Changelog: https://github.com/caspel26/django-ninja-aio-crud/compare/v0.2.2...v0.3.0
🚀 Django Model Auto Async CRUD
-
Now you can give to APIViewSet a vanilla django Model (including its schemas or CRUD will not work) as model class attribute. Like ModelSerializer also forward and reverse relations are supported.
-
define your models.
# models.py
from django.db import models
class Bar(models.Model):
name = models.CharField(max_length=30)
description = models.TextField(max_length=30)
class Foo(models.Model):
name = models.CharField(max_length=30)
active = models.BooleanField(default=False)
bar = models.ForeignKey(Bar, on_delete=models.CASCADE, related_name="foos")
- define your schemas. See Django Ninja Schema documentation
# schema.py
from ninja import Schema
class BarSchemaIn(Schema):
name: str
description: str
class BarSchemaRelated(Schema):
id: int
name: str
description: str
class BarSchemaOut(BarSchemaRelated):
foos: list["FooSchemaRelated"]
class BarSchemaUpdate(Schema):
description: str
class FooSchemaIn(Schema):
name: str
active: bool
bar: int
# This schema will be used into bar schema out for reverse relation
# It can be used for every model related, it's just an example like BarSchemaRelated
class FooSchemaRelated(Schema):
id: int
name: str
active: bool
class FooSchemaOut(FooSchemaRelated):
bar: BarSchemaRelated
class FooSchemaUpdate(Schema):
name: str
active: bool
- then define your views.
# views.py
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
from . import models, schemas
api = NinjaAIO()
class FooAPI(APIViewSet):
model = models.Foo
api = api
schema_in = schemas.FooSchemaIn
schema_out = schemas.FooSchemaOut
schema_update = schemas.FooSchemaUpdate
class BarAPI(APIViewSet):
model = models.Bar
api = api
schema_in = schemas.BarSchemaIn
schema_out = schemas.BarSchemaOut
schema_update = schemas.BarSchemaUpdate
FooAPI().add_views_to_route()
BarAPI().add_views_to_route()
- now run the server and go on /docs urls.
v0.2.2
Oct 03, 2024What's New
- Better error handling implementation by @caspel26
Full Changelog: https://github.com/caspel26/django-ninja-aio-crud/compare/v0.2.1...v0.2.2
v0.2.1
Oct 01, 2024What's Changed
News:
- NinjaAIO class implementation by @caspel26.
Full Changelog: https://github.com/caspel26/django-ninja-aio-crud/compare/v0.2.0...v0.2.1
🥷 NinjaAIO class
- NinjaAIO class inherits from Django Ninja NinjaAPI but it uses built-in parser and renderer which use orjson for data serialization. This class is necessary to make able serialization works.
from ninja_aio import NinjaAIO
from ninja_aio.views import APIViewSet
from test.models import Foo
api = NinjaAIO()
class FooAPI(APIViewSet):
model = Foo
api = api
FooAPI().add_views_to_route()
v0.2.0
Sep 30, 2024What's Changed
News:
- Many to many relation serialization support by @caspel26 in https://github.com/caspel26/django-ninja-aio-crud/pull/7
Bugs:
- Bugfix: router path name in model CRUD router by @caspel26 in https://github.com/caspel26/django-ninja-aio-crud/pull/7
- Bugfix: OneToOne reverse and forward relations by @caspel26 in https://github.com/caspel26/django-ninja-aio-crud/pull/7
Improvements:
- Improved models serializeration by @caspel26 in https://github.com/caspel26/django-ninja-aio-crud/pull/7
🎉 ManyToMany schemas serialization support
- many to many support is finally here. you can define your models and insert the many to many field in reverse and forward relations in ReadSerializerClass.
# models.py
from django.db import models
from .ninja_aio.models import ModelSerializer
class Bar(ModelSerializer):
name = models.CharField(max_length=30)
description = models.TextField(max_length=30)
class ReadSerializer:
fields = ["id", "name", "description", "foos"]
class CreateSerializer:
fields = ["name", "description"]
class UpdateSerializer:
fields = ["name", "description"]
class Foo(ModelSerializer):
name = models.CharField(max_length=30)
active = models.BooleanField(default=False)
bars = models.ManyToManyField(Bar, related_name="foos")
class ReadSerializer:
fields = ["id", "name", "active", "bars"]
class CreateSerializer:
fields = ["name", "active"]
class UpdateSerializer:
fields = ["name", "active"]
- Then add APIViewSets.
```Python
views.py
from ninja import NinjaAPI
from .ninja_aio.views import APIViewSet
from .ninja_aio.parsers import ORJSONParser
from .ninja_aio.renders import ORJSONRenderer
from . import models
api = NinjaAPI(parser=ORJSONParser(), renderer=ORJSONRenderer())
class FooAPI(APIViewSet):
model = models.Foo
api = api
class BarAPI(APIViewSet):
model = models.Bar
api = api
FooAPI().add_views_to_route()
BarAPI().add_views_to_route()
* And that's it! Django Ninja Aio Crud will create dinamically all the schemas that you need and resolve all the relations! If you want to add a view to add, for example, a "bar" or multiple "bars" instances to Foo it could be something like that.
```Python
# views.py
from ninja import Schema
from ninja_aio.schemas import GenericMessageSchema
class AddBarsSchema(Schema):
bars: list[int]
class FooAPI(APIViewSet):
model = models.Foo
api = api
def views(self):
@self.router.patch(
"{id}/add-bars/", response={200: self.schema_out, 404: GenericMessageSchema}
)
async def add_bars(request: HttpRequest, id: int, data: AddBarsSchema):
try:
foo = await models.Foo.objects.prefetch_related("bars").aget(pk=id)
except models.Foo.DoesNotExist:
return 404, {"foo": "not found"}
for bar_id in data.bars:
try:
bar_obj = await models.Bar.objects.aget(pk=bar_id)
except models.Bar.DoesNotExist:
return404, {"bar": "not found"}
await foo.bars.aadd(bar_obj)
await foo.asave()
foo = await models.Foo.objects.prefetch_related("bars").aget(pk=id)
return 200, foo
