  <p>I have system where I have to download a series of objects from a rails app. When they arrive, I add more information onto them, (mainly converting coordinates to google's LatLng and other overlays for a map).</p>
  
  <p>The problem is that when I <code>save()</code> the model, ALL the attributes are appended to the request, where I only want some of then to save (I don't want to save the LatLng objects and other overlays, just the attributes that were downloaded)</p>
