Configuration problems with django and mod_wsgi

Question

I've got problems on getting django to work on apache 2.2 with mod_wsgi. Django is installed and mod_wsgi too. I can even see a 404 page when accessing the path and I can login to django admin. But if I want to install the tagging module I get the following error:

 Traceback (most recent call last):

 ImportError: Could not import settings 'mysite.settings' (Is it on sys.path? Does it have syntax errors?): No module named mysite.settings

My httpd.conf:

 Alias /media/ /home/jim/django/mysite/media/

 <Directory /home/jim/django/mysite/media>
  Order deny,allow
  Allow from all
 </Directory>

 Alias /admin/media/ "/usr/lib/python2.5/site-packages/django/contrib/admin/media/"

 <Directory "/usr/lib/python2.5/site-packages/django/contrib/admin/media/">
  Order allow,deny
  Allow from all
 </Directory>

 WSGIScriptAlias /dj /home/jim/django/mysite/apache/django.wsgi

 <Directory /home/jim/django/mysite/apache>
  Order deny,allow
  Allow from all
 </Directory>

My django.wsgi:

import sys, os

sys.path.append('/home/jim/django')
sys.path.append('/home/jim/django/mysite')

os.chdir('/home/jim/django/mysite')
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'

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

I try to get this to work since a few days and have read several blogs and answers here on so but nothing worked.

Edit:

Now I tried it with this blog post and my wsgi file now looks like this:

import sys
sys.path.insert(0, '/home/jim/django/mysite')
sys.path.insert(0, '/home/jim/django')

import settings

import django.core.management
django.core.management.setup_environ(settings)
utility = django.core.management.ManagementUtility()
command = utility.fetch_command('runserver')

command.validate()

import django.conf
import django.utils

django.utils.translation.activate(django.conf.settings.LANGUAGE_CODE)

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

admin is still working, but I'm getting the same error when I try to install the tagging module.

Answer 1

First,

• Since your admin works, the setting with wsgi is good. Don't bother changing/editing it.

To ensure that it is not a Apache/mod-wsgi setting problem, you can run the development server from the production machine

python manage.py runserver 0:8080

Then point your browser to

http://yoursite.com:8080/

You must see exactly the same behaviour.

Then,

For debugging this problem:

• On the python shell on your server, try import tagging. Clearly, from your traceback, import tagging is where it is raising an error and thats why, settings cannot be imported.

• Then, Just delete the package containing tagging, and do a fresh install by the following command, which knows how to install packages, well.

.

sudo pip install django-tagging
