我有: object1与用户的OneToOneField, object2和用户和object1的ForeignKeys。
在序列化程序中,我想检索object1的名称并将其作为object2中的默认名称。 createAPIView禁止获取操作,而我可以将hiddenfield与currentDefaultUser一起使用。 如何获取用户ID并使用它来检索object1? 我应该使用retreive并创建mixins吗?
class Object1(models.Model):
user= models.ForeignKey(CustomUser, on_delete=models.CASCADE)
object1_name = models.CharField(max_length=30, null=False)
class Object2(models.Model):
user= models.ForeignKey(CustomUser, on_delete=models.CASCADE)
object1 = models.ForeignKey(Object1, on_delete=models.CASCADE)
object2_name = models.CharField(max_length=30, null=False)
class Object_2_Serializer(serializers.ModelSerializer):
user = serializers.HiddenField(
default=serializers.CurrentUserDefault())
class Meta:
model = Object2
fields = ('user', 'object1_name', 'object2_name',)
class object_2_CreateView(generics.GenericAPIView,
mixins.RetrieveModelMixin,
mixins.CreateModelMixin,
):
queryset = Object2.objects.all()
serializer_class = Object_2_Serializer
authentication_classes = (TokenAuthentication,)
permission_classes = (IsAuthenticated,)
lookup_field = 'object1_name'
def post(self, request, *args, **kwargs):
return self.create(request, *args, **kwargs)
def get(self, request, *args, **kwargs):
return self.retrieve(request, *args, **kwargs)
我想要获得object1_name。
