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 POST requests with the browsable API

Now, we want to use the browsable API to compose and send an HTTP POST request to our RESTful Web Service to create a new toy. Go to the following URL in your web browser, http://localhost:8000/toys/. At the bottom of the rendered web page, the browsable API displays the following controls to allow us to compose and send a POST request to /toys/:

  • Media type: This dropdown allows us to select the desired parser. The list will be generated based on the configured supported parsers in the Django REST framework for our web service.
  • Content: This text area allows us to enter the text for the body that will be sent with the POST request. The content must be compatible with the selected value for the media type dropdown.
  • POST: This button will use the selected media type and the entered content to compose and send an HTTP POST request with the appropriate header key/value pairs and content.

The following screenshot shows the previously explained controls...
