Fallback to the primary locale #135

Hi,

Is there a way to fallback the missing translations to the primary_locale?

Let's say I've the following primary locale:

foo:
  example: "Baz"

When I create a new locale file dynamically, let's say:

bar: {}

I'd like to fallback example from foo locale when it's called in the context of bar

<%= t('.bar.example') %>
# I want this to return "Baz"

Does anybody know if this is possible?

Thanks in advance

Using a custom exception handler

module I18n
  class CustomExceptionHandler < ExceptionHandler
    def call(exception, locale, key, options)
      if exception.is_a?(MissingTranslation) && key.to_s != 'i18n.plural.rule'
        if I18n.default_locale.to_s == locale.to_s
          raise exception.to_exception
        else
          I18n.t(key, locale: I18n.default_locale)
        end
      else
        super
      end
    end
  end
end


I18n.exception_handler = I18n::CustomExceptionHandler.new

OR using built in fallbacks functionality
