ExcludeFieldsSerializerMixin

Overview

Make fields read-only for one kind of write, named in the serializer's Meta.

Meta.exclude_create_fields lists fields a create request cannot set, and Meta.exclude_update_fields lists fields an update or partial_update request cannot set. The fields stay in responses. Fields made read-only this way still show as writable in OPTIONS responses: https://github.com/encode/django-rest-framework/discussions/8606#discussioncomment-3899252

The action comes from the view in the serializer's context. When the context has no view, no fields are excluded and every field keeps its declared writability.

Use a serializer with this mixin only on a ViewSet. Only a ViewSet has an action. A DRF generic view such as UpdateAPIView handles writes without one, so the mixin cannot tell a create from an update, and a write through it could set every field that the exclusions lock. Building the fields with any view that has no action in context raises ImproperlyConfigured.
