translate(locale, key, options = {})

Overwrites the Base backend translate method so that it will try each locale given by I18n.fallbacks for the given locale. E.g. for the locale :“de-DE” it might try the locales :“de-DE”, :de and :en (depends on the fallbacks implementation) until it finds a result with the given options. If it does not find any result for any of the locales it will then raise a MissingTranslationData exception as usual.

The default option takes precedence over fallback locales only when it's not a String. When default contains String it is evaluated after fallback locales.

    end
  end
