Serializing Data with DRF

In Chapter 2, we learned how to work with databases and models using Django. All the concepts that we have learned are related to Django and how developers can make the best use of the Django framework to interact with a database. In this chapter, we shall take another step forward to learn how DRF integrates with Django ORM and models to help us create APIs that will be consumed by client applications.

We shall learn in detail the concepts of serialization and deserialization, and how the client interacts with server applications using the JSON data type. Validating every input and fetching data from multiple tables is quite common for developers, so DRF helps to implement a leaner interface for such use cases, with the help of Serializers. DRF provides Serializers that can be customized to work with Django models out of the box. Finally, we shall learn how we can use Serializers in APIViews and Generic Views, which we learned about in the first chapter...
