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.

Running tests to check that throttling policies work as expected

Before Django runs the main body of a class-based view, it performs the checks for each throttle class specified in the throttle classes settings. In the drones and pilots-related views, we wrote code that overrides the default settings.

If a single throttle check fails, the code will raise a Throttled exception and Django won't execute the main body of the view. The cache is responsible for storing previous request information for throttling checking.

Now, we can launch Django's development server to compose and send HTTP requests to understand how the configured throttling rules, combined with all the previous configurations, work. Execute any of the following two commands based on your needs to access the API in other devices or computers connected to your LAN. Remember that we analyzed the difference between them in Chapter 3, Creating API Views, in the Launching Django's development server section.
