How can I send emails in Rails 3 using the recipient's locale?

Question

How can I send mails in a mailer using the recipient\'s locale. I have the preferred locale for each user in the database. Notice this is different from the current locale (I18n

Answer 1

This simple plugin was developed for rails 2 but seems to work in rails 3 too.

http://github.com/Bertg/i18n_action_mailer

With it you can do the following:

def new_follower(user, follower)
  @follower = follower
  @user = user
  set_locale user.locale
  mail :to => @user.email, :subject => t(:new_follower_subject)
end

The subject and mail templates are then translated using the user's locale.
