What's the proper way to handle geographic locales in Ruby on Rails?

Question

I'm surprised to see that Ruby on Rails' i18n doesn't properly support locales such as en-GB, en-US, en-AU, etc. Looking around it seems the task is left to third party libraries and code. I searched around and I found rails-i18n-translation-inheritance-helper but it doesn't seem that active. Is nobody localizing their Rails apps or is there another solution that I'm missing?

Answer 1

You can set your current locale to anything you want using something like

I18n.locale = 'en_US'

To avoid repeating most of the stuff for similar locales, you can then setup proper fallbacks in the i18n initializer like so:

config.i18n.default_locale = 'en'
config.i18n.fallbacks = {
  'en_US' => 'en',
  'en_GB' => 'en',
  'de_DE' => 'de',
  'de'    => 'en'
}

Now you only need to create all your different localization files as fortunately, everything is part of the default i18n gem.
