In this chapter, we used the browsable API feature to navigate through the API with resources and relationships. We added unique constraints to improve consistency for the models in our RESTful Web Service.

We understood the importance of paginating results and we configured and tested a global limit/offset pagination scheme with the Django REST framework. Then, we created our own customized pagination class to make sure that requests weren't able to acquire a huge amount of elements in a single page.

We configured filter backend classes and we added code to the models to add filtering, searching, and ordering capabilities to the class-based views. We created a customized filter and we made requests to filter, search, and order results, and we understood how everything worked under the hood. Finally, we used the browsable API to test pagination, filtering, and ordering.

Now that we improved our RESTful Web Service with unique constraints, paginated results, fitering, searching, and ordering features, we will secure the API with authentication and permissions. We will cover these topics in the next chapter.
