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 authenticated HTTP PATCH requests with Postman

Now, we will use one of the GUI tools we installed in Chapter 1, Installing the Required Software and Tools, specifically, Postman. We will use this GUI tool to compose and send an HTTP PATCH request with the appropriate authentication credentials to the web service. In the previous chapters, whenever we worked with Postman, we didn't specify authentication credentials.

We will use the Builder tab in Postman to compose and send an HTTP PATCH request to update the has_it_competed field for the previously created drone. Follow these steps:

  1. In case you made previous requests with Postman, click on the plus (+) button at the right-hand side of the tab that displayed the previous request. This way, you will create a new tab.
  2. Select PATCH in the drop-down menu at the left-hand side of the Enter request URL textbox.
  3. Enter http://localhost:8000/drones/12 in that textbox at the right-hand side of the drop-down. Replace 12 with the ID generated for...
