CakePHP saving data in HABTM fields - cakephp

Question

I am using these three relations User, Movie and UsersWatchlist.. Where users_watchlists contains movie_id and user_id as attributes.. I have this structure
array(
'User' => array(
'id' => '3'
),
'UsersWatchlist' => array(
'UsersWatchlist' => array(
(int) 0 => '3'
)
)
)
public function watchlist($id = null) {
$userid = '3';
if (!$id && $userid != 3) {
$this->Session->setFlash('Invalid Movie');
$this->redirect($this->referer(array('action' => 'listing')));
}
$this->request->data['User']['User'][] = $userid;
$this->request->data['Movie']['Movie'][] = $id;
debug($this->request->data);
if ($this->User->saveAll($this->request->data)) {
debug("saved");
$this->Session->setFlash('The movie has been added to your watchlist', 'admin/flash_success');
//$this->redirect($this->referer(array('action' => 'listing')));
} else {
debug("saved bo");
$this->Session->setFlash('The movie could not be added to your watchlist. Please, try again.', 'admin/flash_error');
//$this->redirect($this->referer(array('action' => 'listing')));
}
}
I used saveAll method on User but its not saving.. Please provide me solution to save the data..
In Movie model,
public $hasAndBelongsToMany = array('User' => array(
'className' => 'User',
'joinTable' => 'users_watchlists',
'foreignKey' => 'movie_id',
'associationForeignKey' => 'user_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'finderQuery' => '',
'deleteQuery' => '',
'insertQuery' => ''
)
);
In User model,
public $hasAndBelongsToMany = array(
'Movie' => array(
'className' => 'Movie',
'joinTable' => 'users_watchlists',
'foreignKey' => 'user_id',
'associationForeignKey' => 'movie_id',
'unique' => 'keepExisting',
'conditions' => '',
'fields' => '',
'order' => '',
'limit' => '',
'offset' => '',
'finderQuery' => '',
'deleteQuery' => '',
'insertQuery' => ''
)
);
In UsersWatchlist model,
public $belongsTo = array(
'User' => array(
'className' => 'User',
'foreignKey' => 'user_id',
'conditions' => '',
'fields' => '',
'order' => ''
),
'Movie' => array(
'className' => 'Movie',
'foreignKey' => 'movie_id',
'conditions' => '',
'fields' => '',
'order' => ''
)
);

Answer 1

The data array you're trying to save is wrong.
If you're saving throung the User model your structure should be:
array(
'User' => array(
'id' => '3'
),
'Movie' => array(
'Movie' => array(
(int) 0 => '3'
)
)
