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.

Configuring throttling policies in the Django REST framework

Now, we will configure throttling policies for the class-based views related to drones: DroneList and DroneDetail. We will override the values for the following class attributes for the class-based views:

  • throttle_classes: This class attribute specifies a tuple with the names of the classes that will manage throttling rules for the class. In this case, we will specify the ScopedRateThrottle class as the only member of the tuple.
  • throttle_scope: This class attribute specifies the throttle scope name that the ScopedRateThrottle class will use to accumulate the number of requests and limit the rate of requests.

This way, we will make these class-based views work with the ScopedRateThrottle class and we will configure the throttle scope that this class will consider for each of the class based views related to drones.
