Phalcon，Models，How to Action_on cascade set null？

Question

I'm using phalcon, and I'm trying to make the action on cascade set null all values. Now I have this:

$this->hasOne("folder_id", "Common\Models\Folder", "id", array(
            'alias' => 'Folder',
            'foreignKey' => array(
                'action' => Relation::ACTION_CASCADE
            )
        ));

But that will delete the rows, I just want to set null, not delete.

Answer 1

It can't be done via Phalcon. I had to change my db table relation.
