# DRF APISchema
Based on `drf-spectacular`, automatically generate API documentation, validate queries, bodies, and permissions, handle transactions, and log SQL queries.
This can greatly speed up development and make the code more readable.
## Features
- Auto generate API documentation and routes
- Validate queries, bodies, and permissions
- Handle transactions
- Log SQL queries
- Simple to use
```python
@apischema(permissions=[IsAdminUser], body=UserIn, response=UserOut)
def create(self, request: ASRequest[UserIn]):
"""Description"""
print(request.serializer, request.validated_data)
return UserOut(request.serializer.save()).data
```
## Installation
Install `drf-apischema` from PyPI
```bash
pip install drf-apischema
```
Configure your project `settings.py` like this
```py
INSTALLED_APPS = [
# ...
"rest_framework",
"drf_spectacular",
# ...
]
REST_FRAMEWORK = {
"DEFAULT_SCHEMA_CLASS": "drf_spectacular.openapi.AutoSchema",
}
SPECTACULAR_SETTINGS = {
"TITLE": "Your Project API",
"DESCRIPTION": "Your project description",
"VERSION": "1.0.0",
"SERVE_INCLUDE_SCHEMA": False,
'SCHEMA_PATH_PREFIX': '/api',
}
```
## Usage
serializers.py
```python
from django.contrib.auth.models import User
from rest_framework import serializers
class UserOut(serializers.ModelSerializer):
class Meta:
model = User
fields = ["id", "username"]
class SquareOut(serializers.Serializer):
result = serializers.IntegerField()
class SquareQuery(serializers.Serializer):
n = serializers.IntegerField(default=2)
```
views.py
```python
from typing import Any
from django.contrib.auth.models import User
from rest_framework.decorators import action
from rest_framework.mixins import ListModelMixin, RetrieveModelMixin
from rest_framework.permissions import IsAdminUser, IsAuthenticated
from rest_framework.viewsets import GenericViewSet
from drf_apischema import ASRequest, apischema, apischema_view
from .serializers import SquareOut, SquareQuery, UserOut
# Create your views here.
@apischema_view(
retrieve=apischema(summary="Retrieve a user"),
)
class UserViewSet(GenericViewSet, ListModelMixin, RetrieveModelMixin):
"""User management"""
queryset = User.objects.all()
serializer_class = UserOut
permission_classes = [IsAuthenticated]
# Define a view that requires permissions
@apischema(permissions=[IsAdminUser])
def list(self, request):
"""List all
Document here
xxx
"""
return super().list(request)
# will auto wrap it with `apischema` in `apischema_view`
@action(methods=["post"], detail=True)
def echo(self, request, pk):
"""Echo the request"""
return self.get_serializer(self.get_object()).data
@apischema(query=SquareQuery, response=SquareOut)
@action(methods=["get"], detail=False)
def square(self, request: ASRequest[SquareQuery]) -> Any:
"""The square of a number"""
# The request.serializer is an instance of SquareQuery that has been validated
# print(request.serializer)
# The request.validated_data is the validated data of the serializer
n: int = request.validated_data["n"]
# Note that apischema won't automatically process the response with the declared response serializer,
# but it will wrap it with rest_framework.response.Response
# So you don't need to manually wrap it with Response
return SquareOut({"result": n * n}).data
```
urls.py
```python
from django.urls import include, path
from rest_framework.routers import DefaultRouter
from drf_apischema.urls import api_path
from .views import *
router = DefaultRouter()
router.register("test", TestViewSet, basename="test")
urlpatterns = [
# Auto-generate /api/schema/, /api/schema/swagger/ and /api/schema/redoc/ for documentation
api_path("api/", [path("", include(router.urls))])
]
```
## settings
settings.py
```python
DRF_APISCHEMA_SETTINGS = {
# Enable transaction wrapping for APIs
"TRANSACTION": True,
# Enable SQL logging
"SQL_LOGGING": True,
# Indent SQL queries
"SQL_LOGGING_REINDENT": True,
# Use method docstring as summary and description
"SUMMARY_FROM_DOC": True,
# Show permissions in description
"SHOW_PERMISSIONS": True,
# If True, request_body and response will be empty by default if the view is action decorated
"ACTION_DEFAULTS_EMPTY": True,
}
```
## drf-yasg version
See branch drf-yasg, it is not longer supported
## Troubleshooting
### Doesn't showed permissions description of `permission_classes`
Wrap the view with `apischema_view`.
```python
@apischema_view()
class XxxViewSet(GenericViewSet):
permissions_classes = [IsAuthenticated]
```
### TypeError: cannot be assigned to parameter of type "_View@action"
Just annotate the return type to `Any`, as `apischema` will wrap it with `Response`.
```python
@apischema()
@action(methods=["get"], detail=False)
def xxx(self, request) -> Any:
...
```
