I think that I worked out better solution for this.
The model relation:
var $hasAndBelongsToMany = array(
'Friend' =>
array('className' => 'User',
'joinTable' => 'users_users',
'foreignKey' => 'user_id',
'associationForeignKey' => 'friend_id',
),
'Admirer' =>
array('className' => 'User',
'joinTable' => 'users_users',
'foreignKey' => 'friend_id',
'associationForeignKey' => 'user_id',
),
);
The controller:
function addfriend($friend_id = null) {
$this->data = $this->User->read(array('id'), $this->obAuth-
>getUserId());
$friends = array();
foreach ($this->data['Friend'] as $friend) {
$friends[] = $friend['id'];
}
$friends[] = $friend_id;
$admirers = array();
foreach ($this->data['Admirer'] as $admirer) {
$admirers[] = $admirer['id'];
}
$admirers[] = $friend_id;
unset($this->data['Friend']);
unset($this->data['Admirer']);
$this->data['Friend']['Friend'] = $friends;
$this->data['Admirer']['Admirer'] = $admirers;
if ($this->User->save($this->data)) {
$this->Session->setFlash('Added to Friends.');
}
}
Usage:
Simply put link /users/addfriend/10 and the user with id==10 will be
added to logged user friends and logged user will be added to user
with id==10.
Works perfect.
