Question

我有一个使用Django rest创建的REST API。我收到以下错误：

AttributeError: type object 'ContactRequestSerializer' has no attribute 'get_extra_actions'

class ContactRequestSerializer(serializers.ModelSerializer):
class Meta:
    model = ContactRequest
    fields = '__all__'

class ContactFormSerializer(serializers.ModelSerializer):
    class Meta:
        model = ContactForm
        fields = '__all__'

class ProjectRequestSerializer(serializers.ModelSerializer):
    class Meta:
        model = ProjectRequest
        fields = '__all__'

我在所有序列化程序中都指定了相同的属性，并且我从同一个类继承而来，但是问题仍然存在。

我有一个API文件，可在其中创建视图集

    class ContactFormViewSet(viewsets.ModelViewSet):
    queryset = ContactForm.objects.all()
    permission_classes = [
        permissions.AllowAny
    ]
    serializer_class = ContactFormSerializer

# ProjectRequest Viewset
class ProjectRequestViewSet(viewsets.ModelViewSet):
    queryset = ProjectRequest.objects.all()
    permission_classes = [
        permissions.AllowAny
    ]
    serializer_class = ProjectRequestSerializer

    class ContactRequestViewSet(viewsets.ModelViewSet):
    queryset = ContactRequest.objects.all()
    permission_classes = [
        permissions.AllowAny
    ]
    serializer_class = ContactRequestSerializer

然后是我的模型：

...
class ContactRequest(models.Model):
    topic = models.CharField(max_length=30)
    description = models.CharField(max_length=200)
    time = models.CharField(max_length=15)
    project_request = models.ForeignKey(ProjectRequest, on_delete=models.CASCADE)

由于它们看起来都很相似，除了我的两个模型之间的关系之外，我无法弄清楚这个问题。

AttributeError：类型对象“ ContactRequestSerializer”没有属性“ get_extra_actions”
