I18n

1. Customise you own I18n solution. One easy way is to overwrite app/helpers/devise_helper.rb, which is mentioned as "A simple way to show error messages for the current devise resource. If you need to customize this method, you can either overwrite it in your application helpers or copy the views to your application." in the comment.

2. Setting default locale (config/application.rb) config.i18n.default_locale = :sv
