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'
