Django RESTful Web Services

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.

Understanding versioning classes


Sometimes, we have to keep many different versions of a RESTful Web Service alive at the same time. For example, we might need to have version 1 and version 2 of our RESTful Web Service accepting and processing requests. There are many versioning schemes that make it possible to serve many versions of a web service.

The Django REST framework provides five classes in the rest_framework.versioning module. All of them are subclasses of the BaseVersioning class. The five classes allow us to work with a specific versioning scheme.

We can use one of these classes in combination with changes in the URL configurations and other pieces of code to support the selected versioning scheme. Each class is responsible for determining the version based on the implemented schema and to make sure that the specified version number is a valid one based on the allowed version settings. The classes provide different mechanisms to determine the version number. The following are the...
