DRF-inclusions

A django-restframework renderer to side-load related resources.

One drawback of RESTful APIs is that you have to make many calls to fetch all the related resources. DRF-inclusions provides a custom renderer allowing you to sideload those in a single, original request.

DRF-inclusions allows you to specify which serializers to use for included resources, and via the query string the client can specify which resources should be included.

Features:

• arbitrary depth
• option to include all related resources
• de-duplication when the same object is found in multiple parent/related objects
• an effort is made to retrieve related objects in as little DB queries as possible

Installation

pip install djangorestframework-inclusions

Usage

from rest_framework_inclusions.renderer import InclusionJSONRenderer


class MySerializer(...):
    inclusion_serializers = {"some_field": OtherSerializer}


class MyViewSet(...):
    ...
    renderer_classes = (InclusionJSONRenderer,)
