title: Nice way to access value in ruby nested hash
body: <p>I have the following nested hash. How can I quickly access the <code>result_api</code> value, if <code>listing_id</code> is <code>variable</code>?</p>
  
  <pre><code> {"0"=&gt;{"result_api"=&gt;15229, "listing_id"=&gt;4}, "1"=&gt;{"result_api"=&gt;15229, "listing_id"=&gt;2}, "2"=&gt;{"result_api"=&gt;15229, "listing_id"=&gt;1}}
  </code></pre>
