Re: Invalidate cached copy when changes are made.

Thanks for the reply Matias. I'll give signals a try but pagination is
definitely a no go. I want to see all the members at a stretch.
Isn't there a simple way to tell the django cache to get a new copy,
if changes are made?

I'm sure the admin or something must have something like what i
want....
