REST framework takes advantage of this by providing a number of pre-built views that provide for commonly used patterns. If the generic views don't suit the needs of your API, you can drop down to using the regular APIView class, or reuse the mixins and base classes used by the generic views to compose your own set of reusable generic views. Typically when using the generic views, you'll override the view, and set several class attributes. For more complex cases you might also want to override various methods on the view class. For example.
