Django Rest API Pagination not limiting number of objects - django-rest-framework

Question

i followed the documentation but i still get the full list of objects not limited
views.py
from rest_framework.pagination import (LimitOffsetPagination,PageNumberPagination)
class PostView(generics.ListAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
pagination_class = PageNumberPagination
def list(self, request, *args, **kwargs):
self.object_list = self.filter_queryset(self.get_queryset())
serializer = self.get_serializer(self.object_list, many=True)
return Response(serializer.data)
settings.py
REST_FRAMEWORK = {
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 2
}

Answer 1

By implementing the list method yourself, the pagination is no longer applied. Indeed, the list method for a ListAPIView is implemented as [GitHub]:
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)
But you thus do not need to implement the list method yourself. Your view can look like:
from rest_framework.pagination import (LimitOffsetPagination,PageNumberPagination)
class PostView(generics.ListAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
pagination_class = PageNumberPagination
# no list method
