Hi.
First of all, thank you everybody for the answers. I really meant that
I wanted to do that through the admin's page filter system. I forgot
to mention that on the second message I sent.
I'm aware of the possibility to do this filtering through the django
shell, but i couldn't implement it to work at the admin page yet.
There's some interesting work being done about it (and filtering
customizations in general) here:
http://code.djangoproject.com/ticket/5833
But anyway, I didn't know about this neat feature of passing the shell
command to the url using '?modelo__manageable=True'. I guess it's
documented, but I didn't read the docs if the attention it requires.
Thanks for the info.
I guess that I'll try to hardcode it using the template system, while
the feature is still in development. (Hope it will make it's way into
trunk!)
