This may help too - I sort of accidentally stumbled on to this method
while I was working on a project with this thread in mind:
<?php
class User extends AppModel
{
var $name = 'User';
function bindComment ($conditions = null, $order = 'created DESC',
$limit = null, $page = '1')
{
$this->bindModel(array(
'hasMany' => array(
'Comment' => array(
'className' => 'Comment',
'conditions' => $conditions,
'order' => $order,
'limit' => $limit,
'foreignKey' => 'user_id',
'dependent' => true,
'exclusive' => false,
'finderSql' => '',
'counterSql' => ''
)
)
));
}
function beforeDelete()
{
if(parent::beforeDelete())
{
// attach comment model to user so all user's comments
get wiped on
->del
$this->bindComment();
return true;
}
}
}
?>
Basically now, no matter where a "User" is deleted from, it will bind
the Comments model as "dependent" beforehand, and then delete all
Comments associated with the User being removed. This way I don't
always have to have Comments bound to my User, but where I do want user
comments, I can say $User->bindComment();
