django pagination 自定义分页

新建文件 pagination.py(文件名随意)

from rest_framework.pagination  import PageNumberPagination
from rest_framework.response import Response
from collections import OrderedDict


class MyCustomPagination(PageNumberPagination):
   
    page_size = 5 # 每页显示多少个

    page_size_query_param = "size" # 默认每页显示3个，可以通过传入pager1/?page=2&size=4,改变默认每页显示的个数

    max_page_size = 100 # 最大页数不超过100

    page_query_param = "page" # 获取页码数的

    def get_paginated_response(self, data):
        """输出格式"""
        return Response(OrderedDict([
            ('count', self.page.paginator.count), # 整个数据的个数
            ('success', True), # 验证消息
            ('next', self.get_next_link()), # 下一页url
            ('previous', self.get_previous_link()), # 上一页url
            ('results', data) # 当前页的数据
         ]))

使用分页

视图

from app.pagination import MyCustomPagination
class get_view(mixins.CreateModelMixin,
               mixins.ListModelMixin,
               GenericViewSet):
    pagination_class = MyCustomPagination # 使用刚刚自定义的分页

    queryset = models.Student.objects.all()
    serializer_class = get_sreializer

接口数据

{
    "count": 11,
    "success": true,
    "next": "http://127.0.0.1:8000/get_data/?page=2",
    "previous": null,
    "results": [
        {
            "id": 1,
            "name": "cox",
            "age": "12"
        },
        {
            "id": 2,
            "name": "cox",
            "age": "12"
        },
        {
            "id": 3,
            "name": "cox",
            "age": "12"
        },
        {
            "id": 4,
            "name": "cox",
            "age": "12"
        },
        {
            "id": 5,
            "name": "cox",
            "age": "12"
        }
    ]
}
