Question

paginate.py

class StandardResultsSetPagination(PageNumberPagination):
    page_size = 3
    page_size_query_param = 'page_size'
    max_page_size = 5

Serializers.py

class AreaUsersSerializer(serializers.ModelSerializer):

    class Meta:
        model = User
        fields = ('id', 'first_name', 'areas')

Views.py

class AreaUsers(viewsets.ViewSet):
    queryset = User.objects.all()
    serializer_class = AreaUsersSerializer        
    pagination_class = StandardResultsSetPagination  # Not working


    def list(self, request):
        queryset = User.objects.all()[:10]
        serializer = AreaUsersSerializer(queryset, many=True)
        return Response(serializer.data)

我只是想知道为什么这段代码无法应用分页，它在api视图中显示了所有10个值

尝试一下：

class StandardResultsSetPagination(pagination.PageNumberPagination):

    def get_paginated_response(self, data):

        return Response({
            'links': {
                'next': self.get_next_link(),
                'previous': self.get_previous_link()
            },
            'current_page': int(self.request.query_params.get('page', 1)),
            'total': self.page.paginator.count,
            'per_page': self.page_size,
            'total_pages': round(self.page.paginator.count/self.page_size, 1),
            'data': data,
        })

    class AreaUsers(viewsets.ViewSet):
        queryset = User.objects.all()
        serializer_class = AreaUsersSerializer    


        def list(self, request):
            queryset = User.objects.all()[:10]
            paginator = StandardResultsSetPagination()
            page_size = 5
            paginator.page_size = page_size
            result_page = paginator.paginate_queryset(queryset, request)
            serializer = UserSerializer(result_page, many=True)
            return paginator.get_paginated_response(serializer.data)

分页不适用于Django rest_framework中的视图集
