You should be able to use the standard Python getattr call:
print getattr(tag, 'model_name').count()
which dynamically gets an attribute passed as a string.

I have no fixtures/initial_data-files anywhere in my project tree!
Actually, the only file named "initial_data" on my system is djtrunk/

The "ghost-users" only show up when I'm running "./manage.py test".

Hello Django Users,
I'm working on a application that evolves over time. in order to show
both applications we set up virtual hosts in the httpd.conf in the
following way.
ServerName bioinf-dev.erasmusmc.nl

I have kinda the same problem as of today. It just seems to not use

Is there something wrong with having to exact same virtualhosts that
just differ in the specified django settings?
