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.

Understanding decorators that work as wrappers


Now, we will make a few changes to the code in the toys/views.py file to provide support for the OPTIONS verb in our RESTful Web Service. Specifically, we will take advantage of a decorator provided by the Django REST framework.

We will use the @api_view decorator that is declared in the rest_framework.decorators module. We will apply this decorator to our function-based views: toys_list and toys_detail.

The @api_view decorator allows us to specify which are the HTTP verbs that the function to which it is applied can process. If the request that has been routed to the view function has an HTTP verb that isn't included in the string list specified as the http_method_names argument for the @api_view decorator, the default behavior returns a response with an HTTP 405 Method Not Allowed status code.

This way, we make sure that whenever the RESTful Web Service receives an HTTP verb that isn't considered within our function views, we won't generate an...
