5. 1) Setup your application for localizing
a) Change URL format to include locale (in routes.rb)
ex: http://localhost:3000/fr
scope "/:locale", :locale => /en|fr/ do
resources :importantdates
end
b) Add setting to application_controller.rb
before_filter :set_locale
def set_locale
I18n.locale = params[:locale] || I18n.default_locale
end
c)Create .yml files in config/locales for each language you are supporting
