I am writing a behavior which checks a field for duplicates in beforeSave()
and updates the created row in afterSave().
I am wondering what happens to $model->data array if I modify it directly
or I use $model->find() or $model->save() while in the callback.
Do other behaviors and callbacks also receive the same data array?
Am I responsible to leave it as-is after I finish modifying the data?
Do I have to make another instance of the model and do *find*s and *save*s
with that instance?
<?php
function beforeSave(Model $model){
$value = $model->data[$model->alias]['unique_field'];
$duplicates = $model->find('all', array(
'conditions' => array('unique_field', $value)
));
if ($duplicates) { /* ... */ }
*//what happens to $model->data here?*
}
function afterSave(Model $model, $created){
$value = $model->data[$model->alias]['unique_field'];
$model->data[$model->alias]['unique_field'] = strrev($value); //for
demonstration purposes
$model->save($model->data, array('callbacks'=>false));
*//what happens to $model->data here?*
}
Thanks for the input!
P.S. I have to update in afterSave because the unique field depends on the
id, and has a temp value before the id is available.
