Django error with WSGI

[James.DeMichele]

Hello all,

I was hoping someone here might be able to help me figure out what is
wrong with my configuration. Here's my current setup:

Windows 7
Python 2.6.6
Psycopg2-2.3.1
Postgres 9.0
mod_wsgi-win32-ap22py26-3.3.so
Apache 2.2
Django 1.2

First off, I have Django functioning correctly with the dev server,
and can make a call to the database correctly. Now, I wanted to get
WSGI to work with Django. Also, I am able to get the Hello World WSGI
example found here (http://code.google.com/p/modwsgi/wiki/
QuickConfigurationGuide) to work correctly within my Django project
and have it print out "Hello World".

Here's my Apache configuration

WSGIPythonHome "C:/Python"
<VirtualHost *:80>
ServerName sng.dev.com
ServerAlias sng.dev.com

LogLevel info

Alias /media/ C:/code/sng/media

<Directory C:/code/sng/media>
Order deny,allow
Allow from all
</Directory>

WSGIScriptAlias / "C:/code/sng/wsgi/django.wsgi"

<Directory C:/code/sng/wsgi/>
Order allow,deny
Allow from all
</Directory>
</VirtualHost>

Here's what I have in my django.wsgi file:

---------------
path = 'C:\code'
if path not in sys.path:
sys.path.append('C:\code')
path = 'C:\code'
if path not in sys.path:
sys.path.append('C:\code\sng')

os.environ['DJANGO_SETTINGS_MODULE'] = 'sng.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
---------------

Here's the error stack trace:

Django can hide the actual underlying error message in some
circumstances. The problem may be this one:

http://groups.google.com/group/modwsgi/browse_thread/thread/13b4a5faa962d77/dd4d6a03afbe16b6
http://psycopg.lighthouseapp.com/projects/62710/tickets/20
http://archives.postgresql.org/psycopg/2011-01/msg00009.php

The issue as it presents with your error has I believe come up on the
list before, so you might search through the archives in Google
Groups. Don't remember if it was linked to this issue.
