*So I swapped to using WSGI with this apache config *

WSGIScriptAlias / /home/user/python/djcode/cfServer/apache/django.wsgi
WSGIDaemonProcess site-1 threads=30
WSGIProcessGroup site-1


AllowOverride None
Options None
Require all granted


and this django.wsgi

os.environ['DJANGO_SETTINGS_MODULE'] = 'cfServer.settings'

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

Hi Tom,  Jani,

Currently struggling to compile mod_wsgi, or more specifically a shared 
library version of python - something to do with mismatched 32/64 bit 
libraries I think.

Here's an extract from httpd.conf.

RewriteEngine On
RewriteRule ^.*/cfServer/(.*)$ /cgi-bin/django.cgi/$1 [PT]

Options ExecCGI
AddHandler fcgid-script .cgi
# AddHandler cgi-script .cgi
Require all granted


and the relevant django.cgi

#!/usr/local/bin/python
from FcgiWsgiAdapter import list_environment, serve_wsgi

import os, sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'cfServer.settings'
os.environ['ORACLE_HOME'] = '/oracle/11gStdEd'

from django.core.handlers.wsgi import WSGIHandler

# use this to test that fastcgi works and to inspect the environment
# serve_wsgi(list_environment)
# use this to serve django
serve_wsgi(WSGIHandler())

The "FcgiWsgiAdapter" referred to came from 
djangosnippets.org
.

As to error logs, as I mentioned in the original post I don't see anything 
added to any logs when this happens and there is only a warning about the 
ssl library when apache is restarted.

Regards, ADN

Bump  I've had no luck with this and would still appreciate some 
pointers! I've tried re-arranging the order of statements in my model code 
without any improvement.

Problem with tuncated Admin pages in apache + mod_fcgid

[Another Django Newbie]

Hi,

I've just started playing with django this week and was following the
example in the Django Book.

I created an example of my own, based on the models.py in the book and
tested it with manage.py runserver. All worked OK, but when I try it
in apache one of my admin pages is truncated - a number of fields are
left off and there is no Save button. The exact number of fields
truncated depends on whether I use Add from the main page or from the
Add page of another field (so that the affected page is a pop-up)

Apache 2.4.1
mod_fcgid 2.3.6
django 1.3.1
Python 2.7.2
cx-Oracle 5.1.1

Has anyone seen this behaviour? I've looked in apache and django logs
but don't see anything recorded when the page loads. Any ideas greatly
appreciated.

Thanks.
