a question about error_messages_for:

when i retrieve the error messages the error_messages_for display a list errors with the name of input followed the customizable string error.

But if i want to change the name of input on the error message how can i do? imagine for example i need to translate the errors messages in various languages....

You just need to use rails' built-in i18n feature.

Drop a en.yml in config/locales with content like this:

en:     activerecord:         models:             user: "User"         attributes:             user:                 login: "user name"         errors:             messages:                 blank: 'should not be blank'
