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.

Composing requests that filter and order results

We will compose and send an HTTP request to retrieve all the drones whose related drone category ID is equal to 1 and whose value for the has_it_competed field is equal to False. The results must be sorted by name in descending order, and therefore, we specify -name as the value for the ordering query parameter.


The hyphen (-) before the field name indicates that the ordering feature must use descending order instead of the default ascending order.

Make sure you replace 1 with the pk value of the previously retrieved drone category named Quadcopter. The has_it_competed field is a bool field, and therefore, we have to use Python valid bool values (True and False) when specifying the desired values for the bool field in the filter:

http ":8000/drones/?

The following is the equivalent curl command:

curl -iX GET "localhost:8000/drones/?
