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.

Making HTTP GET requests with the browsable API

We just made an HTTP GET request to retrieve the toys resource collection with the browsable API. Now, we will compose and send another HTTP GET request for an existing toy resource with the web browser.

Enter the URL for an existing toy resource, such as http://localhost:8000/toys/3. Make sure you replace 3 with the id or primary key of an existing toy in the previously rendered Toy List. Django will compose and send a GET request to http://localhost:8000/toys/3 and the rendered web page will display the results of its execution, that is, the headers and the JSON data for the toy resource. The following screenshot shows the rendered web page after entering the URL in a web browser with the resource description, Toy Detail:

At the right-hand side of the resource description, the browsable API shows a GET drop-down button. This button allows us to make a GET request to /toys/3 again. If we click or tap the down arrow, we can select the json option...
