If you look at model's source code for 1.11 you have something like:
function del() {
// ...
if ($this->id && $db->delete($this)) {
$this->_deleteMulti($id);
$this->_deleteHasMany($id, $cascade);
$this->_deleteHasOne($id, $cascade);
//...
}
}
Then for example deleteHasOne():
function _deleteHasOne($id, $cascade) {
// ...
foreach($this->hasOne as $assoc => $data) {
if ($data['dependent'] === true && $cascade === true) {
$model =& $this->{$data['className']};
// ...
if($records != false){
foreach($records as $record) {
$model->del($record[$data['className']][$model->primaryKey]);
}
}
}
}
//...
}
}
So (with the exception of deleteMulti() that issues direct SQL delete
statements), each related record when in cascade will issue another del()
call. So it can go as far as your PHP execution time allows it to go.

Asunto: Re: How many levels will del with cascade go?
I am tackling the same issue and would also like to know the best
approach.
