Django + mod_wsgi + apache: ImportError at / No module named djproj.urls

Question

I'm trying to deploy my Django application on my linode server with apache and mod_wsgi.

file: /srv/www/example.com/djproj/django.wsgi

import os
import sys

sys.path.append('/srv/www/example.com/djproj')

os.environ['PYTHON_EGG_CACHE'] = '/srv/www/example.com/.python-egg'
os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'

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

file: /etc/apache2/sites-available/example.com

/etc/apache2/sites-available/example.com
ServerAdmin [email protected]
ServerName example.com
ServerAlias www.example.com

DocumentRoot /srv/www/example.com/public_html

WSGIScriptAlias / /srv/www/example.com/djproj/django.wsgi

<Directory "/srv/www/example.com/djproj">
   Order allow,deny
   Allow from all
</Directory>

ErrorLog /srv/www/example.com/logs/error.log 
CustomLog /srv/www/example.com/logs/access.log combined

When I visit / of my site I get this error:

Environment:

Exception Type: ImportError at /
Exception Value: No module named djproj.urls

I can't get it to work. Ideas?

Answer 1

I second Ignacio Vazquez-Abrams's answer. You must add the path to your project directory as well as the path to its parent directory to sys.path. Here is an example of the WSGI script file I use. I keep the file inside the project directory.

import os
import sys

sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../../")))
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../")))

os.environ["DJANGO_SETTINGS_MODULE"] = "PROJECT_NAME.settings"

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

Answer 2

Either change all your module/package entries and imports to exclude the project name, or put /srv/www/site.com in sys.path as well.

Answer 3

Seconding ayaz' answer. It's important that the paths you're specifying be at the beginning of the search path, which means you need to use insert..

Here's mine. When I was doing an 'append' I was getting intermittent issues. This made it rock solid. Hope this helps.

sys.path.insert(0, '/srv/www/Appname')
sys.path.insert(1, '/srv/www')
