Django mod_python deployment error

Question

I'm trying to deploy a django project via mod_python and I keep getting an error saying a handler module is missing.

My apache config:

    <Location />
            SetHandler python-program
            PythonHandler django.core.handlers.modpython
            SetEnv DJANGO_SETTINGS_MODULE bookmarklet_server.settings
            PythonOption django.root /
            PythonDebug On
            #PythonPath "['', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/local/lib/python2.6/dist-packages']"
    </Location>

The other path is from my attempt to just copy over the default pythonpath, but it didn't help.

A quick test in the python console shows the module should be accesible:

Python 2.6.4 (r264:75706, Nov 2 2009, 14:44:17) [GCC 4.4.1] on linux2 Type "help", "copyright", "credits" or "license" for more information.

>>> import django.core.handlers.modpython

no errors

However loading the site, this error is inadvertendly returned:

Answer 1

Perhaps django isn't in your Pythonpath?

Answer 2

Ok, managed to fix the problem.

This particular import issue was fixed by installing django rather than just having the svn trunk linked into dist-packages. Why this doesn't work for server processes I don't know.

But anyway, there were further issues which were solved by doing a CGI deployment via nginx and eventually the last problem (which also failed my wsgi deployment attempt) was that my /home dir, which is where the files were, was accessible only by myself.

I learned a lot today :)
