This 'magic function' is

if self.stuff != self.__class__.objects.get(id=self.id).stuff:
do_this()

The design pattern is a toaster popup. You can achive this using CSS

this CSS to hide your message area:

The slug field itself doesn't force uniqueness, but you can use

I think the problem is that you are referencing a non-existent (view)
function named 'viewer' in your urls.py. This wasn't a problem in
previous versions, but with the addition of the reverse url lookup,
non-existent views now cause problems.
What I gather is happening is

Yes, I suppose if you wanted you could create a custom form that added
