title: Django Admin popup functionality
body: <p>This topic is fairly common (most explicitly detailed here: <a href="http://www.hoboes.com/Mimsy/hacks/replicating-djangos-admin/" rel="noreferrer">http://www.hoboes.com/Mimsy/hacks/replicating-djangos-admin/</a>), but I'm still having trouble with it.  I'm trying to use the "plus" button functionality used in the admin site where one can add an additional foreign key to a linked entry.  In the admin site, a popup displays allowing the user to submit a new field and then that new value is populated on the original form.</p>
  
  <p>I think my issue centers around the inclusion of this line:</p>
  
  
  
  <p>within the base.html template and the popadd.html template.  Clicking the plus button does not bring up a new window.  The popadd template simply loads in the same tab.  And submitting a new entry does not take the user back to the original form.</p>
  
  <p>The admin site is functional.  I am including ADMIN_MEDIA_PREFIX = '/media/admin/' in the settings.py file.  Does it have something to do with where the RelatedObjectLookups.js lives?  It's currently in an admin directory outside of my project folder.  Do I have to create a symlink?  </p>
  
  <p>Sorry for the noob questions.  Would appreciate any suggestions (as detailed as possible).</p>
