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.

Creating Django views combined with serializer classes

We have created the necessary model and its serializer. It is time to code the necessary elements to process HTTP requests and produce HTTP responses. Now, we will create Django views that use the ToySerializer class that we created previously to return JSON representations of the entities for each HTTP request that our web service will handle. Open the toys/ file. The following lines show the initial code for this file with just one import statement and a comment that indicates we should create the views:

from django.shortcuts import render 
# Create your views here. 

We will create our first version of the web service and we will use functions to keep the code as simple as possible. We will work with classes and more complex code in later examples. First, it is very important to understand how Django and Django REST framework work by way of a simple example.

Now, write the following lines in the restful01/toys/ file...
