Organization of Locale Files in rails app

The following options all worked for me

config.i18n.load_path += Dir["#{Rails.root.to_s}/config/locales/**/*.yml"]

config.i18n.load_path += Dir["#{Rails.root.to_s}/config/locales/**/*.{rb,yml}"]

config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**' '*.{rb,yml}').to_s]

After restarting the webserver of course...

I had a similar issue, I solved it by adding this line to my application.rb config:

# load the subfolders in the locales
config.i18n.load_path += Dir["#{Rails.root.to_s}/config/locales/**/*.{rb,yml}"]

To test the host application you need to change the i18n.load_path to the config folder of your main app and not the dummy spec for testing purposes. Code as follows:

config.i18n.load_path += Dir[Rails.root.join('config', 'locales', '**', '*.{rb,yml}')]
config.i18n.default_locale = :en
