Thanks for your response. Everything works nice now.

I read the reference and fixed the missing slashes and commented out print functions if dev-oriented or added the print option file=sys.stderr if reporting an error.

Nice to learn something before it bites :)

I have decided to keep the django admin-media files untouched in-situ
because it keeps my own static files area less cluttered. It also means
less hassle for me when django tweaks admin templates, js, css and images.

I also decided to use FollowSymLinks so I could stick with the more
generic python rather than python2.6 in the path.

Thanks again

Mike

Because I had prepared this email ready to ask for help, I'm
posting it anyway with the hope that it helps someone.

Everything else was working. Firebug was saying it couldn't find
base.css and I couldn't see anything wrong with the following
excerpts from settings.py and vhosts.conf:

... from settings.py ...

MEDIA_ROOT = '/srv/www/ccm/htdocs/static' MEDIA_URL = '/static/'
ADMIN_MEDIA_ROOT =
'/usr/local/lib64/python/site-packages/django/contrib/admin/media/'

ADMIN_MEDIA_PREFIX = '/media/'

... from vhosts.conf  ...

Alias /media/
/usr/local/lib64/python/site-packages/django/contrib/admin/media

You are missing a trailing slash on filesystem path which may be a
cause of problems.

<Directory
/usr/local/lib64/python/site-packages/django/contrib/admin/media>
AllowOverride None Order deny,allow Allow from all </Directory>

Alias /static/ /srv/www/ccm/htdocs/static/ Alias /tiny_mce/
/srv/www/ccm/htdocs/static/js/tiny_mce/ Alias /jquery/
/srv/www/ccm/htdocs/static/js/jquery/

<Directory /srv/www/ccm/htdocs/> AllowOverride None Order
deny,allow Allow from all </Directory>

Now, in order to get some meaningful error messages I included
this

import sys sys.stdout = sys.stderr

That shouldn't have made any difference because the error message is
from Apache and not from the Python web application.

That workaround to broken WSGI applications is also only need in
mod_wsgi 2.X and earlier and not 3.X. This is because default change
in 3.0 as gave up trying to make people write portable WSGI
applications. Read:

http://blog.dscpl.com.au/2009/04/wsgi-and-printing-to-standard-output...


in my wsgi script - as per the recommendation I found
inhttp://code.google.com/p/modwsgi/wiki/DebuggingTechniques

and after which, I discovered "Symbolic link not allowed or link
target not accessible: /usr/local/lib64/python" in the Apache error
log. This gave the clue that I needed:

/usr/local/lib64/python2.6/site-packages/django/contrib/admin

rather than the one prepared earlier which incorporated /python/
which is a symbolic link.

Google indicated I could have included Options FollowSymLinks and
maybe I should have done that instead.

Maybe an expert who has read this far might care to comment?

I would generally recommend that a copy be made of media directory
into a sub directory of Django site and use it from there instead.
That way you can customise them without fiddling with the originals.
