What is difference between APIView and GenericAPIView?
APIView is a base class. It doesn’t assume much and will allow you to plug pretty much anything to it. GenericAPIView is meant to work with Django’s Models. It doesn’t assume much beyond all the bells and whistles the Model introspection can provide.

Generic views come in handy when you want to display lists, or detail views, for instance. They will manage querying the database, and messaging the user, among other. So generic views are high level functions to help you creating a response from a view.
Should I use APIView or ViewSet?
if your API will have to do a lot of basic CRUD operations (straight read,update,delete of your models), go for the ViewSets so you won’t have to write all the code for the basic stuff. if you require more custom work, go for either Generic Views or APIViews.
When should I use ViewSet and APIView?
APIView allow us to define functions that match standard HTTP methods like GET, POST, PUT, PATCH, etc. Viewsets allow us to define functions that match to common API object actions like : LIST, CREATE, RETRIEVE, UPDATE, etc.

What is generic REST framework?
Generic views are a set of commonly used patterns. They’re built on top of the APIView class, which we presented in the previous article of this series. Their purpose is for you to quickly build API views that map closely to your database models without repeating yourself.
What is Django-REST-framework-serializer-extensions?
The django-rest-framework-serializer-extensions package provides a collection of tools to DRY up your serializers, by allowing fields to be defined on a per-view/request basis. Fields can be whitelisted, blacklisted and child serializers can be optionally expanded.
What is the use of Django REST framework?

What is DRF-writable-nested in Django?
djangorestframework-queryfields allows API clients to specify which fields will be sent in the response via inclusion/exclusion query parameters. The drf-writable-nested package provides writable nested model serializer which allows to create/update models with nested related data.
