Passing along the answer I got to that very question via IRC... I added
the following to my row class:
sub insert {
my $self = $_[0];
$self->created(DateTime->now) unless $self->created;
$self->modified(DateTime->now) unless $self->modified;
goto &{$self->can("SUPER::insert")};
}
sub update {
my $self = $_[0];
$self->modified(DateTime->now);
goto &{$self->can("SUPER::update")};
}
Seems to work just fine... however, it doesn't permit my userland code to set
a forced value for 'modified' (since the code here is always setting it). I
was trying to think through a solution to that and didn't come up with one.
