title: Can't access images and fonts on production Rails
body: <p>I access some static images (favicon, etc) through /assets/image.jpg.
  It works as expected on localhost but when I push in production, I can't access fonts and images.
  Css and js are compiled and working fine.</p>
  
  <p>I've added this to my production.rb file but it still doesn't work : </p>
  
  <pre><code> config.serve_static_files = true
   config.serve_static_assets = true 
   config.assets.compile = true
  </code></pre>
  
  <p>What do I have to write to access them and where ? </p>
