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 Postman


Now, we will use the Builder tab in Postman to compose and send an HTTP POST request to create a new toy. Perform the following steps:

  1. Click on the plus (+) button on the right-hand side of the tab that displayed the previous request. This way, you will create a new tab.
  2. Select Request in the New drop-down menu located in the upper-left corner.
  3. Select POST in the drop-down menu on the left-hand side of the Enter request URL textbox.
  4. Enter localhost:8000/toys/ in that textbox on the right-hand side of the drop-down menu.
  1. Click Body on the right-hand side of Authorization and Headers, within the panel that composes the request.
  2. Activate the raw radio button and select JSON (application/json) in the drop-down menu on the right-hand side of the binary radio button. Postman will automatically add a Content-type = application/json header, and therefore, you will notice the Headers tab will be renamed to Headers (1), indicating to us that there is one key-value...
