Django RESTful Web Services

By: Gaston C. Hillar

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.

Taking advantage of model serializers

In Chapter 1Installing the Required Software and Tools, we created the toy model (the Toy class) and its serializer (the ToySerializer class). When we wrote the code for the ToySerializer class, we had to declare many attributes with the same names that we used in the Toy class. The ToySerializer class is a subclass of the rest_framework.serializers.Serializer superclass; it declares attributes that we manually mapped to the appropriate types, and overrides the create and update methods. However, we repeated a lot of code and information that was already included in the toy model, such as the types and the max_length values that specify the maximum length for each string field.

Now, we will take advantage of model serializers to simplify code and to avoid repeating information that is already included in the model. We will create a new version of the existing ToySerializer class that will inherit from the rest_framework.serializers.ModelSerializer superclass...
