Django RESTful Web Services

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.

Routing URLs to Django views and functions

Now, we have to create a new Python file named in the toys folder, specifically, the toys/ file. The following lines show the code for this file, which defines the URL patterns that specify the regular expressions that have to be matched in the request to run a specific function previously defined in the file. The code file for the sample is included in the hillar_django_restful_03_01 folder, in the restful01/toys/ file:

from django.conf.urls import url 
from toys import views 
urlpatterns = [ 
    url(r'^toys/$', views.toy_list), 
    url(r'^toys/(?P<pk>[0-9]+)$', views.toy_detail), 

The urlpatterns list makes it possible to route URLs to views. The code calls the django.conf.urls.url function with the regular expression that has to be matched and the view function defined in the views module as arguments to create a RegexURLPattern instance for each entry in the urlpatterns list.

Now, we have to replace the...
