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.

Browsing the API with resources and relationships

We will take advantage of the browsable API feature that we introduced in Chapter 5, Understanding and Customizing the Browsable API Feature, with our new web service. Let's start browsing our new RESTful Web Service. Open a web browser and enter http://localhost:8000. The browser will compose and send a GET request to / with text/html as the desired content type, and the returned HTML web page will be rendered.

The request will end up executing the GET method defined in the ApiRoot class within the file. The following screenshot shows the rendered web page with the resource description Api Root:

The Api Root renders the following hyperlinks:

  • http://localhost:8000/drone-categories/: The collection of drone categories
  • http://localhost:8000/drones/: The collection of drones
  • http://localhost:8000/pilots/: The collection of pilots
  • http://localhost:8000/competitions/: The collection of competitions

We can easily access each resource collection...
