A serializer that handles field configuration with multiple actions from ViewSets.
Project description
Action Serializer
Source: https://github.com/gregschmit/drf-action-serializer
PyPI: https://pypi.org/project/drf-action-serializer/
Action Serializer is a Django Rest Framework extension package that provides a Serializer that implements per-action field configuration for use in your drf-powered API.
The Problem: When building APIs, often you want different serializers for different actions, such as less fields on a list view vs a detail view. Normally you would have to build multiple Serializers to support this.
The Solution: This app provides the ModelActionSerializer which allows you to easily configure per-action serialization.
How to Use
$ pip install drf-action-serializer
In your serializer, inherit from action_serializer.ModelActionSerializer.
In your serializer, you can add an action_fields dictionary to the Meta class and use fields, exclude, and extra_kwargs under the action key. The example in this project shows how to render a smaller list of attributes for a list view compared to the detail view.
from django.contrib.auth.models import Group
from action_serializer import ModelActionSerializer
class GroupActionSerializer(ModelActionSerializer):
"""
An example serializer for the Django ``Group`` model, where the ``list`` action
causes less fields to be serialized than normal.
"""
class Meta:
model = Group
fields = ("id", "name", "permissions")
action_fields = {"list": {"fields": ("id", "name")}}
In your ViewSet, just set the serializer like normal:
from rest_framework.viewsets import ModelViewSet
class GroupViewSet(ModelViewSet):
"""
An example viewset for the Django ``Group`` model.
"""
serializer_class = GroupActionSerializer
queryset = Group.objects.all()
Tests
$ python manage.py test
