title: Hash map in ruby?
body: <p>I'm trying to get this object, passed via AJAX:</p>
  
  <pre><code>  Parameters: {"status"=&gt;{"1"=&gt;["14", "1"], "2"=&gt;["7", "8", "12", "13"]}}
  </code></pre>
  
  <p>into something like:</p>
  
  <pre><code>14 -&gt; 1
  1 -&gt; 1
  7 -&gt; 2
  </code></pre>
  
  <p>over which I can iterate.</p>
  
  <p>What's the most elegant way of achieving this?</p>
