title: How to load non-default models?
body: <p>In CakePHP2.x, I have frequently used <code>$uses</code> attribute in controllers but it seems that this attribute is no longer available in CakePHP 3.0.</p>
  
  <p>The only way I know to load models which is not default one is to use <code>loadModel()</code> method. 
  Is this recommended way to load models? Or is there any other way to load models? </p>
