Hello,
while I'm doing my first steps into Rose::DB, I face the following problem:
I am looking for a way to maintain identity of Rose::DB::Object
instances, that share the same PK. ( Represent the same row ).
I hoped deriving from Rose::DB::Object::Cached would achieve this, but
it seems, that this is not true for Instances returned by the
Rose::DB::Object::Manager derived Classes.
Is there a best practice how to handle this?
Regards, Christoph Lamprecht
use strict;
use warnings;
my @classes = qw/
Tko::Person # ISA Rose::DB::Object::Cached
/;
for (@classes) {eval "require $_";
eval "require ${_}::Manager";
};
my $p = Tko::Person->new(id => 3);
$p->load;
print 'name: ',$p->name,", self = [$p]\n";
my $instances = Tko::Person::Manager->get_objects();
for (@$instances){
print 'name: ',$_->name,", self = [$_]\n";
}
undef $p;
$p = Tko::Person->new(id => 3);
$p->load;
print 'name: ',$p->name,", self = [$p]\n";
output:
name: Willi, self = [Tko::Person=HASH(0x8189fd4)]
name: Willi, self = [Tko::Person=HASH(0x8e748d8)]
name: Willi, self = [Tko::Person=HASH(0x8189fd4)]
