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.

Understanding the importance of throttling rules

In Chapter 8, Securing the API with Authentication and Permissions, we made sure that some requests were authenticated before processing them. We took advantage of many authentication schemes to identify the user that originated the request. Throttling rules also determine whether the request must be authorized or not. We will work with them in combination with authentication.

So far, we haven't established any limits on the usage of our RESTful Web Service. As a result of this configuration, both unauthenticated and authenticated users can compose and send as many requests as they want to. The only thing we have limited is the resultset size throughout the configuration of the pagination features available in the Django REST framework. Hence, large results sets are split into individual pages of data. However, a user might compose and send thousands of requests to be processed with any kind of limitation. Of course, the servers or virtual...
