title: Update all with Loopback
body: <p>I like Loopback but this is poorly documented/unexpected stuff here.</p>
  
  <p>I want to use this functionality:</p>
  
  <p><a href="http://apidocs.strongloop.com/loopback/#persistedmodel-updateall" rel="nofollow">http://apidocs.strongloop.com/loopback/#persistedmodel-updateall</a></p>
  
  <p>I assume that</p>
  
  <pre><code>PUT /models
  </code></pre>
  
  <p>will invoke the <code>Model.updateAll()</code> functionality. The above HTTP request is standard out-of-the-box stuff, the stuff that Loopback is made for.</p>
  
  <p>What I want to find out is the mapping between backend functions like Model.updateAll and the API URLs.</p>
  
  <p>In other words, how can I find out if</p>
  
  <pre><code>PUT /Dogs ~ Dogs.updateAll()
  </code></pre>
  
  <p>isn't there a 1:1 mapping here? And if so, why is it not documented well?</p>
