如何让定制的分页类在django rest framework v3.6中工作

from rest_framework.pagination import PageNumberPagination

class CustomPagination(PageNumberPagination):
    page_size = 10  # 每页显示的数量
    page_size_query_param = 'page_size'  # URL参数中指定每页数量的参数名
    max_page_size = 100  # 每页最大显示的数量

from rest_framework.views import APIView
from rest_framework.response import Response

class MyView(APIView):
    pagination_class = CustomPagination

    def get(self, request):
        # 处理GET请求的逻辑
        # ...

        # 获取分页数据
        queryset = MyModel.objects.all()
        paginated_queryset = self.paginate_queryset(queryset)

        # 序列化分页数据
        serializer = MyModelSerializer(paginated_queryset, many=True)

        # 返回分页结果
        return self.get_paginated_response(serializer.data)

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'myapp.pagination.CustomPagination',
    'PAGE_SIZE': 10,
}
