If you need to extend or modify the config/application.rb
just do it at the config/application_custom.rb
file. For example if you want to change de default language to English, just add:
module Consul
class Application < Rails::Application
config.i18n.default_locale = :en
config.i18n.available_locales = [:en, :es]
end
end
Remember that in order to see this changes live you'll need to restart the server.
