我一直试图从用户表（mysql）中删除一个现有的示例，但我一直从用户那里得到错误。delete（）这是我的观点：

@api_view(['GET', 'PUT', 'DELETE'])
def user_api_id(request):
    try:
        id = request.GET.get('id')
        user = User.objects.get(pk=id)
        if request.method == 'GET':
            serializer = UserSerializer(user)
            return Response(serializer.data)

        elif request.method == 'PUT':
            serializer = UserSerializer(user, data=request.data)
            if serializer.is_valid():
                serializer.save()
                return Response(serializer.data)
            return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

        elif request.method == 'DELETE':
            try:
                user.delete()
                return Response(status=status.HTTP_204_NO_CONTENT)
            except ValidationError as ve:
                return Response({"error": str(ve)}, status=status.HTTP_400_BAD_REQUEST)
            except Exception as e:
                return Response({"error": str(e)}, status=status.HTTP_500_INTERNAL_SERVER_ERROR)
    except User.DoesNotExist:
        return Response(status=status.HTTP_404_NOT_FOUND)

当我启动一个DELETE请求时，我会得到这样的结果：

(btw我要删除的用户的id ='john'）
这是我的用户模型：

class User(models.Model):

    id = models.CharField(primary_key=True, max_length=50)

    password = models.CharField(max_length=50)

    name = models.CharField(max_length=25)

    lastname = models.CharField(max_length=25)

    age = models.IntegerField()

    gender = models.CharField(max_length=6)

    email = models.CharField(max_length=50, blank=True, null=True)

    phone = models.CharField(max_length=50, blank=True, null=True)

    address = models.CharField(max_length=50, blank=True, null=True)

    educationallevel = models.CharField(db_column='educationalLevel', max_length=50, blank=True, null=True)  # Field name made lowercase.

    experience = models.CharField(max_length=20, blank=True, null=True)
    is_active = models.BooleanField(default=True)
    
    is_anonymous = models.BooleanField(default=False)
    is_authenticated = models.BooleanField(default=True)
    
    
    USERNAME_FIELD = 'id'
    REQUIRED_FIELDS = []
    

    class Meta:

        managed = False

        db_table = 'user'

这是数据库中的用户表：

CREATE TABLE `user` (
  `id` varchar(50) COLLATE utf8mb4_general_ci NOT NULL,
  `password` varchar(50) COLLATE utf8mb4_general_ci NOT NULL,
  `name` varchar(25) COLLATE utf8mb4_general_ci NOT NULL,
  `lastname` varchar(25) COLLATE utf8mb4_general_ci NOT NULL,
  `age` int NOT NULL,
  `gender` enum('male','female') COLLATE utf8mb4_general_ci NOT NULL,
  `email` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `phone` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `address` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `educationalLevel` varchar(50) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `experience` varchar(20) COLLATE utf8mb4_general_ci DEFAULT NULL,
  `is_anonymous` tinyint(1) DEFAULT '0',
  `is_authenticated` tinyint(1) DEFAULT '1',
  `is_active` tinyint(1) DEFAULT '0',
  PRIMARY KEY (`id`)
)

我试着直接从数据库中删除，它的工作原理如预期。尝试传递一个不存在的id，它返回了用户DOESNOTEXIT。此外，用户表中的id字段在db中的其他表中被引用为外键，但只有用户表有数据。
