Django REST API Tutorial - Guide to Viewsets, Routers and Serializers - Django RestFramework

ViewSets:

ViewSet is a type of class-based view.

Instead of method handlers, like .get() and .post(), it provides actions, like .list() and .create().

The most significant advantage of ViewSets is that the URL construction is handled automatically (with a router class). This helps with the consistency of the URL conventions across your API and minimizes the amount of code you need to write.

There are four types of ViewSets, from the most basic to the most powerful:

ViewSet
GenericViewSet
ReadOnlyModelViewSet
ModelViewSet

They're mostly built out of the classes you got to know in the previous article in this series:
Official Django REST Framework Tutorial - A Beginners Guide:
This is a beginner-friendly guide to the official Django Rest Framework tutorial. If you have struggled to complete the official tutorial on your own, consider this guide a good place to start instead.

After completing this tutorial, the official tutorial should make a lot more sense and help you take full advantage of the awesomeness that is Django REST Framework.

NOTE: If you'd like to learn even more about APIs in Django, I've written an entire book on the subject, Django for APIs. The first few chapters are available for free.
Initial Setup

Once that's done, create a dedicated directory for our code. This can live anywhere on your computer but in a location that is easily accessible. One option, if you're on a Mac computer, is to create a drf directory on your Desktop. That's what we'll do here.

Enter the following commands in your terminal:
