<p>By default, Ember.js will replace each dynamic segment in the URL with the
model object's <code>id</code> property. In the example above, the <code>@model</code> argument
is the <code>photo</code> objects, and their <code>id</code> properties are used to fill in the
dynamic segment in the URL; in this case, either <code>1</code>, <code>2</code>, or <code>3</code>. This
behavior can be customized within <code>PhotoEditRoute</code>'s <code>serialize</code> hook.</p>
