title: django error: ImproperlyConfigured: WSGI application
body: <p>My application was working last night, not sure why it won't work this morning. I think that all I did was to create an app called <code>django</code> to store my models, tests, and views.</p>
  
  <p>Getting this error, running django with the Heroku Postgres application on OS X and dj_database as middleware:</p>
  
  <pre class="lang-none prettyprint-override"><code>  File "/Users/{ME}/Projects/{PROJECT}/{PROJECT}/lib/python2.7/site-packages/django/core/servers/basehttp.py", line 58, in get_internal_wsgi_application
      "could not import module '%s': %s" % (app_path, module_name, e)) django.core.exceptions.ImproperlyConfigured: WSGI application
  '{PROJECT}.wsgi.application' could not be loaded; could not import module
  '{PROJECT}.wsgi': No module named core.wsgi
  </code></pre>
  
  <p>Relevant part of my <code>wsgi.py</code> file:</p>
  
  <pre class="lang-py prettyprint-override"><code>"""
  WSGI config for {PROJECT} project.
  
  This module contains the WSGI application used by Django's development
  server and any production WSGI deployments. It should expose a
  module-level variable named ``application``. Django's ``runserver``
  and ``runfcgi`` commands discover this application via the
  ``WSGI_APPLICATION`` setting.
  
  Usually you will have the standard Django WSGI application here, but
  it also might make sense to replace the whole Django WSGI application
  with a custom one that later delegates to the Django one. For example,
  you could introduce WSGI middleware here, or combine a Django
  application with an application of another framework.
