title: No model named "myapp" even though I've added it in settings.py
body: <p>I'm getting the following error:</p>
  
  <pre><code>ImportError at /
  No module named midi_app
  Request Method: GET
  Request URL:    http://127.0.0.1:8000/
  Django Version: 1.4.1
  Exception Type: ImportError
  Exception Value:    No module named midi_app
  Exception Location: /Users/home/virtualenv/venv/lib/python2.7/site-packages/django/utils/importlib.py in import_module, line 35
  Python Executable:  /Users/home/virtualenv/venv/bin/python
  </code></pre>
  
  <p>I have added my app "midi_app" to the <code>INSTALLED_APPS</code> section in settings.py. I'm not sure why I'm seeing this error. Could the virtualenv have anything to do with it?</p>
  
  <p>Thanks. </p>
  
  <p>UPDATE: I've added as many directories as I can think of and I'm still seeing this error. Please see my path below. Please assist, I'm getting really frustrated. </p>
