Why does my django rest-framework pagination does not work?-CodePudding

I have a Django Restframework project. Here is my view:

class JobView(viewsets.ReadOnlyModelViewSet):
    queryset = Job.objects.all()
    serializer_class = JobSerializer
    filter_backends = [filters.OrderingFilter, DjangoFilterBackend, filters.SearchFilter]
    search_fields = [...]
    ordering_fields = ['jobId']
    ordering = ['-jobId']
    filterset_fields = ['jobId', 'status']
    pagination_class = StandardResultsSetPagination

and my pagination class:

class StandardResultsSetPagination(LimitOffsetPagination):
    page_size = 1

The view is registerd in a router:

router.register(r'jobs', JobView)

The problem is, it does not paginate at all. It just ignores the pagination_class attribute.

I also tried:

class JobView(generics.ListAPIView)

And registered the view without the router. But the problem is the same. It does not paginate and just returns a json list with all jobs.

How can achieve pagination in this view without defining it for the project in settings.py globally?

CodePudding user response：

Does your StandardResultsSetPagination inherit from the correct pagination style? LimitOffsetPagination does not limit the output by default (aside from the PAGE_SIZE setting) and requires query parameters to set the limit. It also does not have a page_size class attribute, contrary to PageNumberPagination.

CodePudding user response：

Just try to replace your pagination class with the below code

from rest_framework.pagination import PageNumberPagination
class CustomPagination(PageNumberPagination):
    page_size = 5
    page_size_query_param = 'page_size'
