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.

Using decorators to enable different parsers and renderers

We will make changes to just one file. After you save the changes, Django's development server will automatically restart. However, you can decide to stop Django's development server and start it again after you finish all the necessary changes.

We will make the necessary changes to use the previously introduced @api_view decorator to make it possible for the RESTful Web Service to work with different parsers and renderers, by taking advantage of generalized behaviors provided by the APIView class.

Now, go to the restful01/toys folder and open the file. Replace the code in this file with the following lines. However, take into account that many lines have been removed, such as the lines that declared the JSONResponse class. The code file for the sample is included in the hillar_django_restful_04_02 folder, in the restful01/toys/ file:

from django.shortcuts import render 
from rest_framework import status 
from toys...
