How to make rails 3 I18n translation automatically safe?

Question

I use rails 3. Is there any easy way to tell I18n to respect 'html safness' of string used in interpolation and make all translated string html safe by default? So if I have this en.yml:

en:
  user_with_name: 'User with name <em>%{name}</em>'

and I use t('user_with_name', :name => @user.name), I get users name html escaped, but <em> and </em> is left as is?

Answer 1

Old question, but if someone wants to achieve this, here's the monkey patch I came up with :

module ActionView
  module Helpers
    module TranslationHelper
      private
      def html_safe_translation_key?(key)
        true
      end
    end
  end
end

Put this in an initializers and that's it! Works with Rails 3.2.6. Only marks the text in localization files as safe, not the interpolation parameters.
