title: Can Emberjs computed property depends on other model property?
body: <p>I have a model:</p>
  
  <pre><code>app.ObjectOne = Em.Object.extend({
      id: null,
      count: null
  });
  </code></pre>
  
  <p>And another model, which computed property 'SomeProperty' I want to depend on property 'count' from ObjectOne</p>
  
  <pre><code>app.ObjectTwo = Em.Object.extend({
      id: null,
      someProperty: function(){
        return count+5;
      }.property('app.SomeObjectController.count')
  
  });
  </code></pre>
  
  <p>So, can I do it that way?
  Or is there any other way to do it; </p>
  
  <p>The main idea is that data of ObjectOne model comes after ObjectTwo, so I what to recompute property and rerender view</p>
