title: Django "Models aren't Loaded Yet"
body: <p>It's been quite a while since I've dealt with django, I'm dealing with some code that may be a bit older, now on Django 1.7.  What is this stacktrace about?</p>
  
  <p>It occurs not via <code>runserver</code>, but rather via a command-line utility that uses an app's models.   Previous questions have pointed to upgrading the wsgi file (which has been done) and creating an <code>AppConfig</code> object (which has been done, albeit it's possible not in complete detail).</p>
