Django RESTful Web Services

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.

Configuring pagination classes

The Django REST framework provides many options to enable pagination. First, we will set up one of the customizable pagination styles included in the Django REST framework to include a maximum of four resources in each individual page of data.

Our RESTful Web Service uses the generic views that work with mixin classes. These classes are prepared to build paginated responses based on specific settings in the Django REST framework configuration. Hence, our RESTful Web Service will automatically take into account the pagination settings we configured, without requiring additional changes in the code.

Open the restful01/restful01/ file that declares module-level variables that define the configuration of Django for the restful01 project. We will make some changes to this Django settings file. The code file for the sample is included in the hillar_django_restful_07_01 folder, in the restful01/restful01/ file. Add the following lines that declare...
