There seem be some loading issue with Rails 4.0 with regards to i18n files

Ideally what should be I18n load paths as per 3+

/Users/joshianiket22/.rvm/gems/ruby-1.9.3-p327@rails3_2/gems/activesupport-4.0.0/lib/active_support/locale/en.yml
/Users/joshianiket22/.rvm/gems/ruby-1.9.3-p327@rails3_2/gems/activemodel-4.0.0/lib/active_model/locale/en.yml
/Users/joshianiket22/.rvm/gems/ruby-1.9.3-p327@rails3_2/gems/activerecord-4.0.0/lib/active_record/locale/en.yml

/Users/joshianiket22/carrierwave_tester/config/locales/en.yml

What is seen in Rails 4.0

/Users/joshianiket22/.rvm/gems/ruby-1.9.3-p327@rails3_2/gems/activesupport-3.2.11/lib/active_support/locale/en.yml

One can clear see the difference between the two the carrierwave en.yml is loaded after a the application specific en.yml and there is your issue

I suggest there is no easy way unless you the change the load_paths in rails application and some how manage to change the order of load_paths of as expected

I have given a pull request over here. Completely at awe of Carrierwave guys to decide on it

Hacky Solution :

I was refraining in giving you this solution earlier but still if you want it that bad here what you can do

define a file in lib directory(let say auto_load_i18n.rb) and assign the lib path to autoload (in application.rb)

config.autoload_paths += %w(#{config.root}/lib)

Inside auto_load_i18n.rb write this

I18n.load_path.delete(Rails.root.join("config/locales/en.yml").to_s)
I18n.load_path << Rails.root.join("config/locales/en.yml").to_s

And require the lib file at the top of your application_controller.rb

require 'auto_load_i18n'
class ApplicationController < ActionController::Base

and I guess everything would work then

You can now understand as to why I was refraining in giving this as a possible solution :)

Hope this help
