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.

Taking advantage of content negotiation classes

The APIView class defines default settings for each view that we can override by specifying the desired values in the settings module, that is, the restful01/ file. It is also possible to override the class attributes in subclasses. In this case, we won't make changes in the settings module, but we have to understand which are the default settings that the APIView class uses. We added the  @api_view decorator, and it automatically makes the APIView use these settings.

The value for the DEFAULT_PARSER_CLASSES setting key specifies a tuple of string whose values indicate the default classes that we want to use for parsing backends. The following lines show the default values:


When we use the @api_view decorator, the RESTful Web Service will be able to handle any of the following content types through...
