In this chapter, we took advantage of the various features included in Django REST Framework that allowed us to eliminate duplicate code and build our API reusing generalized behaviors. We used model serializers, wrappers, default parsing, and rendering options, class based views, and generic classes.
We used the browsable API feature and we designed a RESTful API that interacted with a complex PostgreSQL database. We declared relationships with the models, managed serialization and deserialization with relationships, and hyperlinks. Finally, we created and retrieved related resources and we understood how things work under the hoods.
Now that we have built a complex API with Django REST Framework, we will use additional abstractions included in the framework to improve our API, we will add security and authentication, which is what we are going to discuss in the next chapter.
