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.

Sending HTTP requests with unsupported HTTP verbs

Now, we will compose and send HTTP requests with an HTTP verb that isn't supported for the toys resource collection. Run the following command:

http PATCH :8000/toys/

The following is the equivalent curl command:

curl -iX PATCH localhost:8000/toys/

The previous command will compose and send the following HTTP request: PATCH http://localhost:8000/toys/. The request will try to run the views.toy_list function, that is, the toy_list function declared within the toys/ file. The @api_view decorator we added to this function doesn't include 'PATCH' in the string list with the allowed HTTP verbs. The default behavior when this happens in the APIView class is to return an HTTP 405 Method Not Allowed status code. The following lines show a sample output with the response from the previous request. A JSON content provides a detail key with a string value that indicates the PATCH method is not allowed in the response body:

HTTP/1.0 405 Method Not...
