I am just new to the Django Rest Framework and I want to clearly understand how ListCreateAPIView works. We just can provide a queryset, serializer_class and it will create a read-write endpoint.

I was looking for info on the official doc but didn't find what I want.

Any information will be helpful for me.

the story begins from the get method so when calling get it will call list method
this is how list method looks like it will call queryset and make pagination then serialize the data to returned as response

    def list(self, request, *args, **kwargs):
            queryset = self.filter_queryset(self.get_queryset())
    
            page = self.paginate_queryset(queryset)
            if page is not None:
                serializer = self.get_serializer(page, many=True)
                return self.get_paginated_response(serializer.data)
    
            serializer = self.get_serializer(queryset, many=True)
            return Response(serializer.data)

ListCreateAPIView is a generic APIView that allows for GET (list) and POST (create) requests. You can read the source code and maybe get a better understanding

Basically, ListCreateAPIView has the method get() which will call the method list() in mixins.ListModelMixin. The list method will instance the serializer, filter, paginate the queryset and return a response based on the queryset and serializer you have defined in your class.

If you want a deeper understanding I recommend you to read the source code, it can be confusing at first but when you starting using it you will understand it better.
