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.

Preface

Making HTTP PUT requests with the browsable API


Now, we want to use the browsable API to compose and send an HTTP PUT request to our RESTful Web Service to replace an existing toy with a new one. First, go to the URL for an existing toy resource, such as http://localhost:8000/toys/7. Make sure you replace 7 with the id or primary key of an existing toy in the previously rendered Toy List. The HTML web page that displays the results of an HTTP GET request to /toys/7 plus additional details and controls will be rendered.

At the bottom of the rendered web page, the browsable API displays the controls to compose and send a POST request to /toys/ followed by the controls to compose and send a PUT request to /toys/7. The controls for the PUT request are the same that we already analyzed for the POST request. The PUT button will use the selected media type and the entered content to compose and send an HTTP PUT request with the appropriate header key/value pairs and content.
