【问题描述】：

每当我启动服务器并尝试访问管理页面时，我经常会收到 ValidationError: ['[e-mail]' value must be an integer]。

我已经为项目创建了自定义用户，并按照文档中的说明完成了必要的设置（admin.py、model.py、forms.py）。我还尝试在 settings.py 中编写身份验证后端，但导致另一个错误。 但无法弄清楚为什么 pk 使用 USERNAME_FIELD 作为 pk。

class User(AbstractBaseUser):
    user_id         = models.AutoField(primary_key=True,unique=True)
    username        = models.CharField(max_length=50,unique=True)
    first_name      = models.CharField(max_length=50,blank=True,null=True)
    last_name       = models.CharField(max_length=50,blank=True,null=True)
    email           = models.EmailField(
                        max_length=200,
                        unique=True,
                    )
    date_joined     = models.DateTimeField(default=timezone.now)
    # confirm         = models.BooleanField(default=False)
    # confirm_date    = models.DateTimeField(default=False)
    # phone_no = models.IntegerField(max_length=40)
    state           = models.CharField(max_length=50,blank=True,null=True)
    is_active       = models.BooleanField(default=True)
    is_staff        = models.BooleanField(default=False)
    is_admin        = models.BooleanField(default=False)


    objects = UserManager()

    USERNAME_FIELD  = 'email'

    REQUIRED_FIELDS = ['username']

【问题讨论】：

user_id 字段中的内容是什么？

请问我不明白这个问题，请

我的怀疑是您将电子邮件存储在 user_id 字段中，您可以查询您的数据库以查看 user_id 字段的内容吗？

问题是存储在request.session[SESSION_KEY] 中的内容。你是怎么设置的？您有自定义身份验证后端吗？

请看一下自定义身份验证后端。谢谢

【参考方案1】：

user_id = models.AutoField(primary_key=True)

删除“unique = True”。

【讨论】：

这个答案完全没用 - unique arg 虽然对于主键（根据定义是唯一的）无用，但不会更改列的类型。
