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 requests that use customized paginated results

Launch Django's development server. If you don't remember how to start Django's development server, check the instructions in Chapter 3, Creating API Views, in the Launching Django's development server section.

Now, we will compose and send an HTTP GET request to retrieve the first page for the drones with the value for the limit query parameter set to 500. This value is higher than the maximum limit we established:

http GET ":8000/drones/?limit=500"

The following is the equivalent curl command:

curl -iX GET "localhost:8000/drones/?limit=500"

The code in the get method for the views.DroneList class-based view will use the new settings we added to enable the customized offset/limit pagination, and the result will provide us with the first eight drone resources because the maximum value for the limit query is set to 8. The value specified for the limit query parameter is greater than 8, and therefore, the maximum value of 8 is used, instead...
