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.

Defining the requirements for a complex RESTful Web Service


So far, our RESTful Web Service performed CRUD operations on a single database table. Now, we want to create a more complex RESTful Web Service with the Django REST framework to interact with a complex database model.

A drone is an IoT (short for Internet of Things) device that interacts with many sensors and actuators, including digital electronic speed controllers linked to engines, propellers, and sensors. A drone is also known as an Unnamed Aerial Vehicle (UAV). We will code a RESTful Web Service that will allow us to register competitions for drones that are grouped into drone categories. In our previous RESTful Web Service, we had toys grouped in toy categories and we used a string field to specify the toy category for a toy. In this case, we want to be able to easily retrieve all the drones that belong to a specific drone category. Thus, we will have a relationship between a drone and a drone category.

We must be able to perform...
