如何将Model.viewset中的查找字段更改为Django Rest框架中的其他唯一参数？

from rest_framework import viewsets
from .serializers import YourModelSerializer
from .models import YourModel

class YourModelViewSet(viewsets.ModelViewSet):
    serializer_class = YourModelSerializer
    queryset = YourModel.objects.all()
    lookup_field = 'unique_field'  # 将唯一字段名设置为 'unique_field'

    def get_object(self):
        queryset = self.filter_queryset(self.get_queryset())
        filter_kwargs = {self.lookup_field: self.kwargs[self.lookup_field]}
        obj = get_object_or_404(queryset, **filter_kwargs)
        self.check_object_permissions(self.request, obj)
        return obj
