Hi All
I'm experiencing a problem that I can't unset records from the data[] in
the afterFind callback when the model a related model.
To show my issue clearly I've add this aferFind function to a model (assume
I'd like to filter all returned records out for some reason):
public function afterFind($results, $primary = false) {
$results = parent::afterFind($results, $primary);
unset($results[0]);
return $results;
}
This works fine for primary models, however not for related models (record
is not unset).
I've traced it back to this part of the _filterResults function in
DBOSource.php:
1128 foreach ($results as &$result) {
1129 $data = $linkedModel->afterFind(array(array($className =>
$result[$className])), false);
1130 if (isset($data[0][$className])) {
1131 $result[$className] = $data[0][$className];
1132 }
1133 }
Line 1130 just ignores the record unset since $data[0][$className] is not
set - it was just unset!
If I change the code like this, it works for both primary and related:
1128 foreach ($results as $key => &$result) {
1129 $data = $linkedModel->afterFind(array(array($className =>
$result[$className])), false);
1130 if (isset($data[0][$className])) {
1131 $result[$className] = $data[0][$className];
1132 else {
1134 unset($results[$key]);
1135 }
1133 }
Am I doing something wrong or is this a cake issue?
Thanks!
Kevin
