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.

Defining hyperlinks with serializers.HyperlinkedModelSerializer

Now, add the following code to the file to declare the DroneSerializer class. The code file for the sample is included in the hillar_django_restful_06_01 folder in the restful01/drones/ file:

class DroneSerializer(serializers.HyperlinkedModelSerializer): 
    # Display the category name 
    drone_category = serializers.SlugRelatedField(queryset=DroneCategory.objects.all(), slug_field='name') 
    class Meta: 
        model = Drone 
        fields = ( 

The DroneSerializer class is a subclass of the HyperlinkedModelSerializer class. The DroneSerializer class declares a drone_category attribute that holds an instance of serializers.SlugRelatedField with its queryset argument set to DroneCategory.objects.all() and its slug_field...
