title: Accessing meta information passed in a json server response
body: <p>I am using the Ember-Data Rest-Adapter and the JSON returned from my server looks basically like the one in the <a href="https://github.com/rails-api/active_model_serializers#attributes">Active Model Serializers Documentation</a></p>
  
  <pre><code>{
    "meta": { "total": 10 },
    "posts": [
      { "title": "Post 1", "body": "Hello!" },
      { "title": "Post 2", "body": "Goodbye!" }
    ]
  }
  </code></pre>
  
  <p>Fetching the data from the server works but unfortunately I am not able to figure out where I can access the meta information from my JSON response.</p>
  
  <p>Based on my research in ember-data's github issue, support for meta information seems to be <a href="https://github.com/emberjs/data/issues/595">implemented</a> with commit <a href="https://github.com/tchak/data/commit/1787bff5f9154d9c09f46830e48dfb5e14953fb1">1787bff</a>. </p>
  
  <p>But even with the test cases I was not able to figure out how to access the meta information.</p>
  
  <pre><code>App.PostController = Ember.ArrayController.extend({
     ....
     requestSearchData: function(searchParams){
        posts = App.Post.find(searchParams);
        this.set('content', posts);
        // don't know how to access meta["total"]
        // but I want to do something like this:
        // this.set('totalCount', meta["total"])
     }
  })
  </code></pre>
  
  <p>Can anybody of you shed some light on this for me, please? I am aware that the Ember api is moving fast but I am sure I am just missing a small part and that this is actually possible.</p>
