title: 'str' object is not callable Django
body: <p>I'm new to Django and thought I'd go through a few tutorials before branching out on my own. I'm trying to program the calendar app described here: <a href="http://lightbird.net/dbe/cal1.html" rel="nofollow">http://lightbird.net/dbe/cal1.html</a>. However, their URLconfigs don't seem to be working for me as I get the following error:</p>
  
  <pre><code>TypeError at /admin/
  
  'str' object is not callable
  
  Request Method:         GET
  Request URL:    http://ec2-23-20-82-228.compute-1.amazonaws.com:8000/admin/
  Django Version:     1.4
  Exception Type:     TypeError
  Exception Value:    
  
  'str' object is not callable
  
  Exception Location:     /usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py in get_response, line 111
  Python Executable:  /usr/bin/python

  </code></pre>
  
  <p>If anyone could point me in the right direction, it'd be greatly appreciated!</p>
