Django序列化器配置分页器

1.编写分页器方法

from rest_framework import pagination

class Pagination(pagination.PageNumberPagination):
    def get_paginated_data(self, data):
        return {
            "total": self.page.paginator.count,
            "data": data
        }

    def get_paginated_response(self, data):
        return build_ret(total=self.page.paginator.count, data=data)

2.在Django的Settings里面添加配置

REST_FRAMEWORK = {
    # 下面的Pagination就是上面写的类文件地址
    'DEFAULT_PAGINATION_CLASS': 'util.pagination.Pagination',
    'PAGE_SIZE': 10
}

3.配合序列化器一起使用

from django.http import JsonResponse

class PlanView(ListAPIView):
    """
    计划列表
    """
    queryset = user_model.Plan.objects.filter().order_by("-id")
    serializer_class = PlanSerializer

    def list(self, request, *args, **kwargs):
        data_list = self.paginate_queryset(self.filter_queryset(self.get_queryset()))
        serializer = PlanSerializer(data_list, many=True)
        return JsonResponse("total": self.paginator.page.paginator.count, "data": serializer.data)
