django auth 支持相同的用户名吗？
我有两个数据库，我必须将用户信息从这些数据库移至 django。问题是用户名重复（这些是其他用户）。又是如何解决的呢？

它不会“解决”多个用户名 -
django.contrib.auth.models.User.username具有unique=True因此每个用户名都必须是唯一的。当您尝试添加具有相同用户名的第二个用户时，数据库会通过抛出数据库
IntegrityError来为您解决该问题。如果您有一个具有多个用户名的工作身份验证系统，那么您显然不会使用用户名作为用户的唯一标识符登录。
也许您正在使用电子邮件地址进行登录，用户名字段只是“天赋”（几乎像这样） - 在这种情况下，我可能会将用户名字段修改得更长，并将电子邮件地址存储在用户名字段/用户名中轮廓模型。

您还可以删除该唯一约束并编写自己的身份验证后端，该后端知道如何查找您的唯一用户/检查其凭据。每个用户一定有/某些/独特之处，对吧？

It doesn't 'solve' multiple user names -
django.contrib.auth.models.User.usernamehasunique=Trueso each one must be unique.The database would solve that problem for you by spitting out a database
IntegrityErrorwhen you try to add a second user with the same username.If you have a working auth system with multiple usernames, then you're clearly not logging in with the username as a user's unique identifier.
Maybe you're using email addresses for login with the username field as just "flair" (almost like SO) - in which case I might modify the username field to be longer and store the email address in the username field / username in a user profile model.

You could also potentially remove that unique constraint and write your own authentication backend that knows how to find your unique user / check its credentials. There must be /something/ unique about each user, right?
