Django rest framework override page_size in ViewSet

Django rest framework override page_size in ViewSet

In Django REST framework, you can override the default page_size for pagination in a ViewSet by specifying it in the corresponding pagination class that you use with the view. Pagination classes in DRF define how paginated responses are generated.

Here's how you can override the page_size for a ViewSet:

  1. Create a Custom Pagination Class:

    You need to create a custom pagination class that inherits from the pagination class you're currently using (usually PageNumberPagination, LimitOffsetPagination, or CursorPagination).

    For example, if you're using PageNumberPagination:

    from rest_framework.pagination import PageNumberPagination class CustomPageNumberPagination(PageNumberPagination): page_size = 20 # Your custom page size

    If you're using a different pagination class, replace PageNumberPagination with the appropriate class.

  2. Use the Custom Pagination Class in Your ViewSet:

    In your ViewSet, override the pagination_class attribute to use your custom pagination class.

    from rest_framework.viewsets import ModelViewSet from .models import YourModel from .serializers import YourModelSerializer from .pagination import CustomPageNumberPagination # Import your custom pagination class class YourModelViewSet(ModelViewSet): queryset = YourModel.objects.all() serializer_class = YourModelSerializer pagination_class = CustomPageNumberPagination # Use your custom pagination class

    Make sure to replace YourModel and YourModelSerializer with your actual model and serializer.

By following these steps, you'll be able to override the page_size for pagination in your ViewSet using a custom pagination class. This allows you to customize the number of items displayed per page in your paginated API responses.
