've added an I18n option to allow to look up a translation with the default locale when it's missed with another specific locale.

This is a useful option if you don't want your page will crash when misses a translation and you don't want to use the default option in each translation. It's inspired by the gettext behaviour.

For example, I have this code in an initializer:

  I18n.use_default_locale_on_missing_translation = true
  I18n.default_locale = :en

And two translation files, en.yml and es.yml:

  en:
    hello: 'hello'
    hello_world: 'hello world'




es:
    hello_world: 'hola mundo'

When I execute this code:

  I18n.t :hello, :locale => :es

Rails returns hello instead of send an error
