Django rest_framwork中ApiView实现分页

在使用Django rest_framwork中ApiView实现分页并自定义返回数据

自定义分页格式

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


class AdaptPagination(PageNumberPagination):
    page_size = 10  # 每页数目
    page_query_param = 'page'  # 前端发送的页数关键字名，默认为"page"
    page_size_query_param = 'limit'  # 前端发送的每页数目关键字名，默认为None

    # max_page_size = 100  # 前端最多能设置的每页数量

    def get_paginated_response(self, data):
        return Response(OrderedDict([
            ('count', data.get('count', self.page.paginator.count)),
            ('next', self.get_next_link()),
            ('previous', self.get_previous_link()),
            ('msg', data.get('msg', 'success')),
            ('code', data.get('code', 0)),
            ('data', data.get('data', data))
        ]))  

rest_framwork中ApiView实现分页

from basis.serializers import UserSerializer, CabinetsSerializer
from basis.models import Cabinets
from rest_framework.views import APIView


class CabinetsViewSet(APIView):
    def get(self, request):
        # 获取所有数据
        queryset = Cabinets.objects.filter(cabinet=True)
        # return MyResponse(data=serializer.data, code=0, msg='success', count=queryset.count())

        # 创建分页对象
        p = AdaptPagination()

        # 在数据库中获取分页数据
        pager_roles = p.paginate_queryset(queryset=queryset, request=request, view=self)
            #对分页数据进行序列化
        serializer = CabinetsSerializer(instance=pager_roles, many=True)
        data = {
            'msg': '成功',
            'code': 0,
            'data': serializer.data
        }
        return p.get_paginated_response(data)
