title: Ember find model by Id
body: <p>In my Ember app, I have a complex model that looks like below (kind of contains 2-dimensional array)</p>
  
  <pre><code>[
      [
          {
              id: 'Section1_123',
              label: 'abc'
          },
          {
              id: 'Section1_456',
              label: 'xyz'
          }
      ]
  ],
  [
      [
          {
              id: 'Section2_123',
              label: 'abc'
          },
          {
              id: 'Section2_456',
              label: 'xyz'
          }
      ]
  ]
  </code></pre>
  
  <p>There are a lot of other attributes, but this is the overall structure.</p>
  
  <p>Now my question is can I drill-down &amp; find a specific object. It has unique ids (as shown in the example above)</p>
  
  <p>So I need something like model.findBy(Id)
  I then need to change/set some values for that object. Say I want to change the obj.label from 'abc' to 'abc_NEW'</p>
  
  <p>Just to add, The main model is actually a simple JS array...but the inside objects (e.g. those with id: 'Section1_123', etc) are actually Ember objects</p>
