Python Django UUIDField问题

我尝试使用以下模型使UUIDField在python django中工作：

class Ticket(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=50)

但是，当我尝试将模型的实例添加到数据库时，它返回以下错误： 在/票证处输入错误/ 强制使用Unicode：需要字符串或缓冲区，找到UUID

UUIDField的文档非常短，对我没有帮助

编辑：我导入了uuid，下面是完整的回溯： 环境：

Request Method: GET

编辑2：我的序列化程序如下所示：

class TicketSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Ticket
        fields = ('url', 'id', 'name')

def __unicode__(self):
    return self.id

def __unicode__(self):
    return str(self.id)

编辑3：

我发现了错误。我的模型出错了。我的unicode看起来像这样：

class TicketSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Ticket
        fields = ('url', 'id', 'name')

def __unicode__(self):
    return self.id

def __unicode__(self):
    return str(self.id)

---

当然，这是行不通的

您可能应该使用以下内容：

class TicketSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = Ticket
        fields = ('url', 'id', 'name')

def __unicode__(self):
    return self.id

def __unicode__(self):
    return str(self.id)

请发布完整的回溯。您在项目中添加了“导入uuid”？请添加整个回溯。Django REST框架序列化程序中可能有问题。您是否将

序列化程序.UUIDField（）

用于您的ID？我添加了serializer@icam0考虑把你的决心作为一个答案，并接受它来解决这个问题。
