If you are already familiar with serializers and serializer fields, you can skip this section. DRF Serializers and Serializer Fields – A Primer (Optional) In this post, we will learn just how to do implement your own custom serializer fields. Inspecting these automatically generated fields can be a useful tool for determining how to customize the relationship style. In this tutorial we will build from scratch a Django API with token-based user authentication. However when it comes time to add user authentication, the official documentation offer a dizzying array of choices.
