Django REST框架-根据查询参数进行过滤

因此，通过@limelights，我设法完成了我想要的工作，这是代码：

class PassengerList(generics.ListCreateAPIView):    model = Passenger    serializer_class = PassengerSerializer    # Show all of the PASSENGERS in particular WORKSPACE    # or all of the PASSENGERS in particular AIRLINE    def get_queryset(self):        queryset = Passenger.objects.all()        workspace = self.request.query_params.get('workspace')        airline = self.request.query_params.get('airline')        if workspace: queryset = queryset.filter(workspace_id=workspace)        elif airline: queryset = queryset.filter(workspace__airline_id=airline)        return queryset
