How Django rest framework override page size in ViewSet

Question

I am having problem with django rest framework pagination. I have set pagination in settings like -

'DEFAULT_PAGINATION_CLASS':'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 1

Below is my viewset.

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()

I want to set different page size for this viewset. I have tried setting page_size and Paginate_by class variables but list is paginated according to PAGE_SIZE defined in settings. Any idea where I am wrong ?

Hello @kartik,

Fixed this by creating custom pagination class. and setting desired pagesize in class. I have used this class as pagination_class in my viewset.

from rest_framework import pagination

class ExamplePagination(pagination.PageNumberPagination):       
       page_size = 2

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()
    pagination_class=ExamplePagination

Simple solution is set it like

pagination.PageNumberPagination.page_size = 100 

In ViewSet.

class HobbyCategoryViewSet(viewsets.ModelViewSet):    
    serializer_class = HobbyCategorySerializer
    queryset = UserHobbyCategory.objects.all()
    pagination.PageNumberPagination.page_size = 100 

Hope it helps!!

Thanks!!
