How to avoid adding the default Locale in generated URLs?

Ok I understand much better. Indeed, you almost did it.

You just need a very useful operator in Ruby: ||

If the first value exists, it's used, otherwise the second argument is taken into account.

def set_locale
  I18n.locale = params[:locale] || :en
end
