尝试获取序列化程序UserSerializer上的字段ProDetails的值时出现AttributeError。序列化器字段可能命名不正确，并且与CustomUser示例上的任何属性或键都不匹配。原始例外文本为：CustomUser对象没有属性ProDetails。

Models.py（示例网站）

class CustomUser(AbstractBaseUser, PermissionsMixin):
    username=None

    is_shopCreated = models.BooleanField(default=False)
    last_login = models.DateTimeField(null=True, blank=True)

Serializer.py（示例网站）
