Remember to be sure to throw an instance of the
Doctrine_Record_UnknownPropertyException
exception class if filterSet() or filterGet() fail to find the property.
Transitive Persistence
Doctrine offers both database and application level cascading operations. This section will
explain in detail how to setup both application and database level cascades.
Application-Level Cascades
Since it can be quite cumbersome to save and delete individual objects, especially if you deal
with an object graph, Doctrine provides application-level cascading of operations.
Save Cascades
You may already have noticed that save() operations are already cascaded to associated
objects by default.
Delete Cascades
Doctrine provides a second application-level cascade style: delete. Unlike the save()
cascade, the delete cascade needs to be turned on explicitly as can be seen in the following
code snippet:
Listing
7-112
// models/User.php
class User extends BaseUser
{
// ...
public function setUp()
{
parent::setup();
// ...
}
}
$this->hasMany('Address as Addresses', array(
'local' => 'id',
'foreign' => 'user_id',
'cascade' => array('delete')
)
);

Here is the same example in YAML format. You can read more about YAML in the YAML
