Me too. Does new->load to be restricted to unique keys? Couldn't there
be a way to provide a query and call the manager under the hood to
find, say, the first matching record?
I'm using something like
###########################################
sub db_find_or_create {
###########################################
my($self, $class, $query) = @_;
my $cmgr = Rose::DB::Object::ConventionManager->new();
$method = "get_" . $cmgr->class_to_table_plural($class);
my $files = (__PACKAGE__ . "::${class}::Manager")->$method(
query => $query
);
if($files->[0]) {
if(wantarray) {
return($files->[0], 0);
} else {
return $files->[0];
}
}
my $rec = (__PACKAGE__ . "::$class")->new(@$query);
if(wantarray) {
return($rec, 1);
} else {
return $rec;
}
}
which I'm calling like
my($obj, $was_created) = $self->db_find_or_create(
"Someclass", [field => "value"]);
Is there a smarter way?
