I have similar situations where I'd have a has-many relation where the
"many" table has a timestamp. Then I'l like to add a shortcut on
Artitst has_many Cd's.
$s->resultset("Artist")->lastcd();
That does just does
return $self->cds()->search({},{page => 1,rows => 1, order_by =>
"createtime desc"})->next();
Which fails horrible if there is no relation.... and I'd just like an
"undef" :-)
Anyway . it's just for convenience, adding af few more lines of code
solves the problem.
