Ok. But how would I do this dynamically?
What I am trying to achieve is some sort of 'persistent filter'. I
would like members interested in some category to be accesible under
/admin/members/interested_in/something for each category. Would that
be possible this way?

You want this...

http://blog.dougalmatthews.com/2008/10/filter-the-django-modeladmin-set/

Be aware though, of a bug* in manage.py that, if you dumpdata with
only your app specified, you will get entries for the proxy model as
well.
The proxy model entries will screw up your next loaddata, so I
recommend specifying each model to dump in your dumpdata command.


*the bug may have been fixed, but the report in trac does not show any
resolution

If you're on Django 1.1 beta or newer you can create a new model that
is a proxy subclass of your existing one, then crete a seperate
ModelAysedmin for it and overide the queryset() method on it to return
your filtered queryset.

Use an arbitrary changelist

[TiNo]

Hi,
I would like a second changelist for an app. Besides the changelist that
shows all members, I would like to show a changlist that show all members
interested in some category. I now I can apply a list filter in the main
list, but I rather have a separate list where the admin returns to after
editing someone from the list, and provide some actions in the object-tools
like sending an email to all members interested in that category.

How do I create a view with a changelist? I know I can override the
Changelist's get_query_set method, but with what parameters do I instantiate
it?

thanks,

TiNo
