drf-crud-proxy 0.5.0

Separate serializers for parsing requests and returning responses in DRF

This package provides extended Django REST Framework generic views and viewsets that provide the possibility to specify different serializers for reading the incoming request and presenting the response.

This is super handy in situations where you want to, for example, let the user send a ForeignKey attribute, but present the related object alongside the response instead of only the database ID.

Requirements

• Python 3.6, 3.7, 3.8, 3.9, 3.10 and 3.11

• Django 3.2, 4.0, 4.1 and 4.2 (basically works with older versions as well, but they’re EOL)

• Django REST Framework 3.8 or newer (probably works on any 3.x version)

Installation

pip install drf-crud-proxy

Usage

Import the generic views and subclass your own views from them. Specify request_serializer_class and/or response_serializer_class to the view (both default to DRF’s own serializer_class attribute).

# api/views.py

from drf_crud_proxy import generics
from app.models import MyModel
from api.serializers import MyModelCreateSerializer, MyModelSerializer


class MyModelListCreateView(generics.ProxiedListCreateAPIView):
    queryset = MyModel.objects.all()
    request_serializer_class = MyModelCreateSerializer
    response_serializer_class = MyModelSerializer

The incoming request is handled with MyModelCreateSerializer and the response with MyModelSerializer.

If you want to customize the data on either situation, override get_request_data and/or get_response_data methods in the view.

The package also supports the so-called PUT-as-create behavior that was removed from DRF in its 3.0 release. Note that the user has to have model permissions for the corresponding create behavior (POST request).

NOTE: The PUT-as-create functionality doesn’t have tests (yet).

Inspiration

This functionality in DRF is something I’ve needed in numerous Django projects, so hopefully this will help someone else too :)

This package has been built on top of the ideas presented by the great vintasoftware’s drf-rw-serializers (https://github.com/vintasoftware/drf-rw-serializers) package. Thanks!
