Rule for updating through a view.

Ok, I found the documentation on using views to udpate the underlying
database. But I can't seem to get my head around making it actually
work, because updates may change only a few columns, and the columns
in my views come from multiple tables.

Could someone provide an example (CC'ing me, please, as I'm not on the
list) of setting up a rule on a joined view to udpated both the
underlying tables?

Thanks,
