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 unsupported HTTP OPTIONS requests with command-line tools

Sometimes, we don't know which are the HTTP methods or verbs that a resource or resource collection supports in a RESTful Web Service. In order to provide a solution to this problem, we can compose and send an HTTP request with the OPTIONS HTTP verb and the URL for the resource or the resource collection.

If the RESTful Web Service implements the OPTIONS HTTP verb for a resource or resource collection, it will build a response with an Allow key in the response header. The value for this key will include a comma-separated list of HTTP verbs or methods that it supports. In addition, the response header will include additional information about other supported options, such as the content type it is capable of parsing from the request and the content type it is capable of rendering in the response.

For example, if we want to know which HTTP verbs the toys collection supports, we can run the following command:

http OPTIONS :8000/toys...
