Apache and mod_python trouble

[Tonu Mikk]

Hello,

I am having trouble configuring Apache and mod_python to work with my
project.

I am using Ubuntu Linux 7.10 with Apache 2. My project is in
/var/www/polls directory. This is also where the settings.py file is.
This directory and all files and directories are owned by www-data (the
user under which Apache is running) and they have 755 rights.

I have configured Apache httpd.conf file like so (only relevant parts
are included):

<Directory "/var/www/polls/">
Order allow,deny
allow from all
</Directory>

<Location "/polls/">
SetHandler python-program
PythonHandler django.core.handlers.modpython
PythonPath "['/var/www/polls'] + sys.path"
SetEnv DJANGO_SETTINGS_MODULE polls.settings
PythonDebug On
</Location>

I am getting the following error when I access ciaran.dmc.umn.edu/polls
. Any help is appreciated.

Thanks, Tonu

You either want to have '/var/www' in PythonPath or specify DJANGO_SETTINGS_MODULE as just settings, not polls.settings. As it is now Python will be looking for /var/www/polls/polls/settings.py (then searching the rest of sys.path for it when it's not found).

Which one you want rather depends on the imports you use in the rest of your project. If you import from 'polls.whatever' then you need '/var/www' in PythonPath.  If you omit the 'polls' part in your imports, then you need '/var/www/polls' in your PyrhonPath.

Karen, thank you. I changed my Location directive to

<Location "/polls/">
SetHandler python-program
PythonHandler django.core.handlers.modpython

PythonPath "['/var/www'] + sys.path"

SetEnv DJANGO_SETTINGS_MODULE polls.settings
PythonDebug On
</Location>

I am now able to get past the previous error. However, I now get the
error about URLConf. I was able to run the project on the development
server with the current URL configuration. I am not quite sure what I
need to change in my URLConf file. Thanks for your help.

Request Method: GET
Request URL: http://ciaran.dmc.umn.edu/polls/

Using the URLconf defined in |polls.urls|, Django tried these URL
patterns, in this order:

1. ^ ^$
2. ^ ^poll/(?P<slug>[^\.^/]+)/$
3. ^ ^create/$
4. ^ ^help/$
5. ^ ^results/(?P<slug>[^\.^/]+)/$
6. ^ ^admin/
7. ^ ^site_media/(?P<path>.*)$
8. ^admin/

The current URL, |polls/|, didn't match any of these.

The URLConf in polls/directory is following:

from django.conf.urls.defaults import *

urlpatterns = patterns('',
# Example:
(r'^', include('polls.pollngo.urls')),

# Uncomment this for admin:
(r'^admin/', include('django.contrib.admin.urls')),
)

The URLConfi in pollngo directory is following:

from django.conf.urls.defaults import *
from django.views.generic.simple import direct_to_template

urlpatterns = patterns('pollngo.views',
(r'^$', 'index'),
(r'^poll/(?P<slug>[^\.^/]+)/$', 'question'),
(r'^create/$', 'create'),
(r'^help/$', 'help'),
(r'^results/(?P<slug>[^\.^/]+)/$', 'results'),
)

urlpatterns += patterns('',
(r'^admin/', include('django.contrib.admin.urls')),
)

Looks like you're trying to call /polls/ but your urls.py has the
directory as /poll/
