I agree that performing a group of actions in a single transaction is one of
the prettiest features of RDBO, and I also like John's approach to making
these shortcuts to Manager routines. I find myself constantly re-writing my
table relationships for manager calls.

That was pretty much my position, too -- I was looking for something more
semantically appropriate. My task was trivial to solve in one or two ways, I
just didn't see any examples on how to do this stuff elegantly. What I am

Hello,
What is the recommended idiom for deleting a single object from a
one-to-many relationship? Using the textbook example,
$p = Product->new(name => 'Kite');
$p->prices({ price => 1.23, region => 'US' },
{ price => 4.56, region => 'UK' });
$p->save; # database is modified here
