<p>Im trying to filter an ng-repeat by an id value.</p>

<pre><code>$scope.filter = $stateParams.id;  --&gt; 56a1832a36dc3d0e00c7aa3f
</code></pre>

<p>Heres the model for the Item Object with relevant vlues</p>

<pre><code>var ItemSchema = new Schema({

  title: {
    type: String,
    maxlength: 150
  }
  user: {
    type: Schema.ObjectId,
