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 unique constraints


The RESTful Web Service doesn't use any constraints, and therefore, it is possible to create many drone categories with the same name. We don't want to have many drone categories with the same name. Each drone category name must be unique in the database table that persists drone categories (the drones_dronecategory table). We also want drones and pilots to have unique names. Hence, we will make the necessary changes to add unique constraints to each of the following fields:

  • The name field of the DroneCategory model
  • The name field of the Drone model
  • The name field of the Pilot model

We will learn the necessary steps to edit existing models and add constraints to fields that are already persisted in tables and to propagate the changes in the underlying database by running the already analyzed migrations process.

Make sure you quit Django's development server. Remember that you just need to press Ctrl + C in the terminal or Command Prompt window in which it is running...
