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.

Generating and using tokens

Now, we will launch our default Python interactive shell in our virtual environment and make all the Django project modules available to write code that will generate a token for an existing user. We will do this to understand how the token generation works.

Run the following command to launch the interactive shell. Make sure you are within the restful01 folder in the terminal, Command Prompt, or Windows Powershell:

python shell

You will notice that a line that says (InteractiveConsole) is displayed after the usual lines that introduce your default Python interactive shell. Enter the following code in the Python interactive shell to import all the things we will need to retrieve a User instance and generate a new token. The code file for the sample is included in the hillar_django_restful_08_02 folder, in the restful01/ file.

from rest_framework.authtoken.models import Token 
from django.contrib.auth.models import User 

Enter the following...
