title: Django - need a get_FOO_display for a foreign field in a form
body: <p>I've got a form template, to which I'm passing the form info as well as the object itself. I can use <code>{{ object.get_FOO_display }}</code> no problem for choice fields when the choice field is a part of the object itself, but I'm looking for an easy way to do the same for the foreign fields that are in the form.</p>
  
  <p>I'm building this into a class-based view, so ideally any suggestions could be coded independent of references to specific fields.</p>
  
  <p>Thanks!</p>
