# WorkflowFieldsSerializerMixin

## Overview

Adds the workflow fields to a serializer whose model enables ``class Vueda.Workflow``.

It sits just above ``ModelSerializer``, below flex-fields, so ``?f=`` and ``?omit=`` select the
workflow fields the same way they select a model field. A workflow field the serializer declares
itself replaces the default and does not have to be listed in ``Meta.fields``.
