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.

Working with different content types

In Chapter 3, Creating API Views, when we composed and sent POST and PUT commands, we had to use the use the -H "Content-Type: application/json" option to indicate curl to send the data specified after the -d option as application/json. We had to use this option because the default content-type in curl is application/x-www-form-urlencoded.

Now, our RESTful Web Service goes beyond JSON and it can also parse application/x-www-form-urlencoded and multipart/form-data data specified in the POST and PUT requests. Hence, we can compose and send a POST command that sends the data as application/x-www-form-urlencoded.

We will compose and send an HTTP request to create a new toy. In this case, we will use the -f option for HTTP.

This option serializes data items from the command line as form fields and sets the Content-Type header key to the application/x-www-form-urlencoded value. Run the next command:

http -f POST :8000/toys/ name="Ken in Rome" description="Ken loves...
