问题描述
我设置Devise使用用户名而不是电子邮件地址登录，因为我们很多用户与配偶共享同一个电子邮件地址。这是我们服务的独特市场。但每个配偶需要单独的帐户来记录个性仪器结果。
I set up Devise to log in with a username instead of email address because a significant number of our users share the same email address with their spouse. It is a unique market that we serve. But each spouse needs separate accounts to record personality instrument results.
数据库不再需要一个唯一的电子邮件地址，因此它将接受两个帐户相同的电子邮件地址。然而，Devise仍然需要每个帐户的唯一电子邮件地址。有没有一个设置或工作，我可以用来改变这个？
The database no longer requires a unique email address so it will accept the same email addy for two accounts. However, Devise is still requiring a unique email address for each account. Is there a setting or a work around that i can use to change this?
推荐答案
查看配置/初始化/ devise.rb 。您可以更改默认身份验证密钥，默认值为：email 为任何您想要的，例如：
Look in the config/initializers/devise.rb. You can change the default authentication key, which by default is :email to be anything you want, for example:
config.authentication_keys = [：username]
