title: Access Asset Path from Rails Controller
body: <p>I'm sharing a configuration yml file client side, that I need to also load on the server side, I've placed it inside app/assets/javascripts/configuration.yml</p>
  
  <p>I can use #{asset_path 'configuration.yml'} inside a view to get the path, but I can't inside a controller. I could access directly using "#{Rails.root}/app/assets/javascripts/configuration.yml" but when deploying the filename gets the digest string appended. </p>
  
  <p>How can I get the same path from a controller?</p>
