Django filter过滤器

DJango-filter模块使用:

目前,过滤器django_filter只能在ListAPIView的子类中使用

1. 过滤

   • ```python
     from rest_framework.generics import ListAPIView
     from django_filters.rest_framework import DjangoFilterBackend
     class MYfilter(ListAPIView):

     queryset = Students.objects.all()
     serializer_class = StudentsSerializer
     filter_backends = [DjangoFilterBackend]
     filter_fields = ("id",)
     #注意,filter_fields的值必须是一个元组!!!!
     

     - 使用方法

     在网址url之后追加——-/?id=1

          
     
     2. ### 排序
     
        - ```python
          from rest_framework.filters import OrderingFilter
          from rest_framework.generics import ListAPIView
          class MYfilter(ListAPIView):
              queryset = Students.objects.all()
              serializer_class = StudentsSerializer
              filter_backends = [OrderingFilter]
              ordering_fields = ['id']

   • 使用方法

     在网址url之后追加------/?ordering=xx
     xx为ordering_fields中准备的用来作为排序基准的字段
     倒序为在xx前加上-号
