How do I add I18n locale dictionaries from gem to Rails Application

Question

I have a gem that makes use of I18n locale dictionaries that reside in lib/locales/*.yml inside my gems folder.

When the gem is initialized I want to load these dictionaries into my rails application, but I cannot figure out how:

This is what I tried:

I18n.load_path += Dir.glob("lib/locales/*.{rb,yml}")

Unfortunately this does not work when the gem is loaded inside my Rails App. When I call I18n.t("foo") I get "translation missing: en, foo".

I will probably have to provide the full path to the locales when invoking I18n.load_path, but I cannot figure out how.

Any hints?

Answer 1

use __FILE__

Dir.glob( File.dirname(__FILE__) + "lib/locales/*.{rb,yml}" ) 

Answer 2

For the record, if you put your locales in <GEM_ROOT>/config/locales, they will be picked up automatically.
