# PerActionSerializerMixin

## Overview

A ViewSet mixin that picks the serializer class per action.

Set ``<action>_serializer_class`` on the viewset, such as ``update_serializer_class`` or
``partial_update_serializer_class``, to serialize that action with its own class. An action
without one uses ``serializer_class``.
