title: Completely remove attribute from Backbone.js model
body: <p>I am trying to totally remove an attribute from a backbone model.  The model is being sent to an API that isn't very flexible, and it will break if I send additional attributes over the ones I'm supposed to send, so I need to remove an attribute so it no longer exists.</p>
  
  <p>I tried <code>model.unset</code>, from <a href="https://stackoverflow.com/questions/10605730/remove-an-attribute-from-a-backbone-js-model">this question</a>, but when I print out the object the attribute I'm trying to remove is still listed, just with a value of null.</p>
  
  <p>I need the attribute to be completely gone.</p>
  
  <p><strong>My basic structure is:</strong> </p>
  
  <pre><code>model.unset("AttrName", "silent");
  </code></pre>
