CakePHP 2.1 Saving HABTM Fields

I have two models User and Movie .. Where are they associated with UsersWatchlist ..

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' => ''
))

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' => ''
))
public $belongsTo = array(
    'User' => array(
        'className' => 'User',
        'foreignKey' => 'user_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    ),
    'Movie' => array(
        'className' => 'Movie',
        'foreignKey' => 'movie_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    ))

I created a "watch" action in the UserController .. Code below

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']['id'] = $userid;
    $this->User->UsersWatchlist->create();
    debug($this->User->UsersWatchlist->saveAll(array('user_id' => '2', 'movie_id' => 3)));
    if ($this->User->UsersWatchlist->saveAll($this->request->data)) {
        $this->Session->setFlash('The movie has been added to your watchlist', 'admin/flash_success');
        $this->redirect($this->referer(array('action' => 'listing')));
    } else {
        $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')));
    }  
}

So, I get an error message when saving .. Please tell me the solution

First, your data should look like this (if you want to save it through a user model):

$this->request->data = array(
    'User' => array(
        'id' => '2',
    ),
    'Movie' => array(
        'Movie' => array(
            (int) 0 => '3',
        ),
    ),
);

The main error that I see is that you are trying to save through the join model, where you have to save the User model. Therefore, in the controller use:

$this->User->saveAll($this->request->data)

If the data is as described above, it should stop. I thought I answered your question here .
