I18n::Backend::Advanced

This is a drop-in replacement for I18n::Backend::Simple which allows inline references to other keys (in other files). References are expanded during init_translations. This way, it also works with packages like i18n-js.

Add this line to your application's Gemfile:

gem "i18n-backend-advanced"

And then execute:

$ bundle

Set I18n::Backend::Advance as default I18n.backend.

# somewhere in application.rb
I18n.backend = I18n::Backend::Advanced.new

Now you can use references in your locale files.

# config/locales/de/application.yml
de:
  application:
    cancel: Abbrechen
    greet: "Hallo %{user}!"
    inbox:
      one: "Eine Nachricht"
      other: "%{count} Nachrichten"

    submit: Abschicken

# config/locales/de/languages.yml
de:
  languages:
    de: Deutsch
    en: Englisch
    es: Spanisch
    ...

# config/locales/de/users.yml
de:
  users:
    submit: ~> application.submit

    index:
      cancel: ~> application.cancel # t("users.index.cancel") => Abbrechen
      greet: ~> application.greet   # t("users.index.greet, user: "Max") => Hallo Max!
      inbox: ~> application.inbox   # t("users.index.inbox, count: 1) => Eine Nachricht
                                    # t("users.index.inbox, count: 2) => 2 Nachrichten
      languages: ~> languages       # t("users.index.languages.en") => Englisch
      submit: ~> users.submit       # t("users.index.submit") ~> Abschicken
