Django RESTful Web Services

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 DELETE requests with the browsable API

Now, we want to use the browsable API to compose and send an HTTP DELETE request to our RESTful Web Service to delete an existing toy resource. First, go to the URL for an existing toy resource, such as http://localhost:8000/toys/7. Make sure you replace 7 with the id or primary key of an existing toy in the previously rendered Toy List. The HTML web page that displays the results of an HTTP GET request to /toys/7, plus additional details and controls, will be rendered.

At the right-hand side of the Toy Detail title, you will see a DELETE button. Click or tap this button. The web page will display a modal requesting confirmation to delete the toy resource. Click or tap the DELETE button in this modal.

The browsable API will compose and send an HTTP DELETE request to /toys/7 and we will see the results of the call in the web browser. The following screenshot shows a web browser displaying the HTTP status code 204 No Content in the response...
