DRF框架GenericAPIView之排序查询

Posted 2020-12-17 小公瑾

一、使用方法

1.引入方式

from rest_framework.filters import OrderingFilter

2.添加引擎

将OrderingFilter引擎添加到filter_backends列表中，也可以添加到全局

filter_backends = [DjangoFilterBackend, OrderingFilter]

3.指定排序字段

使用ordering_fields指定需要排序的字段

ordering_fields = [\'id\', \'name\', \'leader\', \'programmer\', \'tester\']

二、完整代码展示

from rest_framework.response import Response
from rest_framework import status
from rest_framework.generics import GenericAPIView
from django_filters.rest_framework import DjangoFilterBackend
from rest_framework.filters import OrderingFilter
from .models import Projects
from .serializers import ProjectsModelSerializer


class ProjectsPage(GenericAPIView):
    \'\'\'
    类视图
    \'\'\'
    queryset = Projects.objects.all()
    serializer_class = ProjectsModelSerializer

    filter_backends = [OrderingFilter]
    ordering_fields = [\'id\', \'name\', \'leader\', \'programmer\', \'tester\']

    def get(self, request, pk=None):
        qs = self.get_queryset()
        qs = self.filter_queryset(qs)
        serializer_obj = self.get_serializer(instance=qs, many=True)
        return Response({\'code\': 0, \'res\': "success", \'msg\': serializer_obj.data}, status=status.HTTP_200_OK)

三、结果验证

如果是数字则默认为从小到大排序，字符串默认为以ASCII码从小到大排序，排序的查询字符串参数默认为ordering，如果要进行倒序排列，则在需要排序的字段前面指定一个减号（-）即可，如：ordering=-name

1.顺序排序

2.倒序排序
