title: How to create Backbone Collection from a JSON API call that returns root parameters as well as array
body: <p>Backbone.js noob here. </p>
  
  <p>I want to create a collection, from a JSON API external to my application. Specifically, the api from <a href="http://api.stackoverflow.com/1.1/">Stackoverflow</a>. I know I should set the url parameter from a collection like this:</p>
  
  <pre><code>App.Collections.Users = Backbone.Collection.extend({
      model: User,
      url: "http://api.stackoverflow.com/1.1/users/800271;562692?jsonp=?&amp;key=blahblah"
  });
  </code></pre>
  
  <p>The problem is that the JSON API returns something like:</p>
  
  <pre><code>{
   "total": 2,
   "users": [
    {
     "user_id": 800271,
    },
    {
     "user_id": 800272,
    }
   ]
  }
  }
  </code></pre>
  
  <p>How do I ignore the "total" attribute?</p>
