Simplifying the code using ViewSets

We have seen how we can optimize our code and make it more concise using class-based generic views. ViewSets and routers help us further simplify our code. As the name indicates, ViewSets are a set of views represented in a single class. For example, we used the AllBooks view to return a list of all books in the application and the BookDetail view to return the details of a single book. Using ViewSets, we could combine both these classes into a single class.

The code needed to implement all this functionality could be as simple as specifying the serializer and queryset. For example, a view that allows you to manage all these actions for your user model could be defined as tersely as the following:

class UserViewSet(viewsets.ModelViewSet...
