drf 自带BaseFilterBackend

过滤器

常用于数据筛选，如只查单个user下的东西

from rest_framework.filters import BaseFilterBackend

class MineFilterBackend(BaseFilterBackend):
    FILED="id"
    def filter_queryset(self, request, queryset, view):
        user_id = request.user['id']
        return queryset.filter(**{self.FILED:user_id})
		
#用type继承类
type("MineBackend",(MineFilterBackend,),{"FILED":"xxx_id"})

使用

class UserInfoView(mixin.RetrieveModelMixin, GenericViewSet):
    filter_backends = [MineFilterBackend]
    queryset = models.UserInfo.objects.all()
    serializer_class = account.UserInfoSerializer
