所以我按照文档推荐的方法对AbstractBaseUser进行了子类化,从而创建了自己的用户模型。这里的目标是使用一个名为mob_phone的新字段作为注册和登录的识别字段。
它为第一个用户带来了魅力。它将用户名字段设置为空 - 空白。但是当我注册第二个用户时,我得到“UNIQUE约束失败:user_account_customuser.username”。
我基本上想完全取消用户名字段。我怎样才能做到这一点?
我尝试了很多其他地方的建议,但无济于事。我基本上需要找到一种方法,使用户名字段不唯一或完全删除它。
干杯!

好吧,我是个白痴。发布后几秒钟就出现了明显的解决方案:
username = models.CharField(max_length=40, unique=False, default='')
只需覆盖用户名字段并使其不唯一。
橡皮鸭理论在行动......

可能是因为您已经在数据库中输入了一些必须与约束相矛盾的数据。因此,请尝试删除该数据或整个数据库,然后再次运行该命令。
