title: Background image not working in rails style.css on production
body: <p>Background image style works fine on local as there is no <code>digest</code> on locale, but on production, after <code>assets:precompile</code>, all assets add fingerprints and there is no non-digested asset names in Rails 4. Due to this,</p>
  
  <pre><code>background-image: url('abc.png')
  </code></pre>
  
  <p>does not work.</p>
  
  <p>Is there any way to let background images work after <code>assets:precompile</code>?</p>
