ok. i have no idea.
maybe there's something a little different...
delete() deletes in the db, and internally logs/marks the item
purge() would operate on a result set, look for items marked
deleted, and then splice the array
in practice it would be:
my $rose= Rose::DB::Object->get();
foreach my $item ( @$rose ) {
foreach my $suborindate ( @$item{subordinates} ) {
if ( $test ) {
$suborindate->delete();
}
}
if ( $test ) {
$item->delete();
}
}
$rose->purge();
purge would then reflexively loop the result set, looking for items
marked deleted first as items, then subordinates ( no need to work
backwards, as a parent would clear a child ), and splice the list
accordingly.
its a half brained / half assed idea-- i'm sure there are better
ways- and this would need to be a future planning thing.
as-is though, rose is a bit odd -- you can't really loop the same
object 2x in code if there's a delete
which also brings up another idea:
how about including a null hash/array for with_object relationships
that don't match? i find myself testing for these things a lot. am
i the only one who keep running into this?
