title: pycharm unresolved reference on new file added to Django Project
body: <p>I added a new python file named <code>chartcall.py</code> into my django (1.11.1) project in Pycharm 2017.1.3, Python 3.6. <br>
  When I import this new file into my <code>views.py</code> I get an unresolved reference on the import.  This is only happening with the scripts I created.  chartcall does run when I debug it. Thanks ahead of time for the input. </p>
  
  <pre><code>from django.shortcuts import render
  import chartcall
      def home(request):
          orders, dollars = orders_by_day()
          return render(request, 'home.html', {orders, dollars})
  </code></pre>
