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.

Setting permission policies

We will configure permission policies for the class-based views that work with the Drone model. We will override the value for the permission_classes class attribute for the DroneDetail and DroneList classes.

We will add the same lines of code in the two classes. We will include the IsAuthenticatedOrReadOnly class and our recently declared IsCurrentUserOwnerOrReadOnly permission class in the permission_classes tuple.

Open the restful01/drones/ file and add the following lines after the last line that declares the imports, before the declaration of the DroneCategorySerializer class:

from rest_framework import permissions 
from drones import custompermission 

Replace the code that declares the DroneDetail class with the following code in the same file. The new lines are highlighted in the code listing. The code file for the sample is included in the hillar_django_restful_08_01 folder, in the restful01/drones/ file:

class DroneDetail(generics...
