devise - Require username at registration

Question

Ive been searching and cant seem to find a question that answers this. Im pretty new to devise. Ive added a username column to my users model, and added the username field to the registration form.

But how can I require that the username field be filled out upon registration? Also check thats its unique?

如果您希望通过用户名（而不是设计默认电子邮件）登录，Ryan Bates 在他的RailsCasts 第 210 集：自定义设计中介绍了您，请参阅自定义登录要求的最后一节。

但是，如果用户名是 User 表中的附加字段，请将其添加为 attr_accessible 并编写正常的 rails 验证。例子：

validates :username, :presence => true, :uniqueness => true

它可能还需要对视图进行一些自定义以标准化验证错误显示。
