Django RESTful Web Services

By: Gaston C. Hillar

Overview of this book

Django is a Python web framework that makes the web development process very easy. It reduces the amount of trivial code, which simplifies the creation of web applications and results in faster development. It is very powerful and a great choice for creating RESTful web services. If you are a Python developer and want to efficiently create RESTful web services with Django for your apps, then this is the right book for you. The book starts off by showing you how to install and configure the environment, required software, and tools to create RESTful web services with Django and the Django REST framework. We then move on to working with advanced serialization and migrations to interact with SQLite and non-SQL data sources. We will use the features included in the Django REST framework to improve our simple web service. Further, we will create API views to process diverse HTTP requests on objects, go through relationships and hyperlinked API management, and then discover the necessary steps to include security and permissions related to data models and APIs. We will also apply throttling rules and run tests to check that versioning works as expected. Next we will run automated tests to improve code coverage. By the end of the book, you will be able to build RESTful web services with Django.

Working with class-based views

We will write our RESTful Web Service by coding class-based views. We will take advantage of a set of generic views that we can use as our base classes for our class-based views to reduce the required code to the minimum and reuse the behavior that has been generalized in the Django REST framework.

We will create subclasses of the two following generic class views declared in the rest_framework.generics module:

  • ListCreateAPIView: This class view implements the get method that retrieves a listing of a queryset and the post method that creates a model instance
  • RetrieveUpdateDestroyAPIView: This class view implements the get, delete, put, and patch methods to retrieve, delete, completely update, or partially update a model instance

Those two generic views are composed by combining reusable bits of behavior in the Django REST framework implemented as mixin classes declared in the rest_framework.mixins module. We can create a class that uses multiple inheritance and...
