now, want user can add games model, user_id should added automatically( acessing session data). how can achieve ?

first, highly recommend official blog tutorial, because cover questions you.

in controller:

public function add() {     if ($this->request->is('post') {         $this->request->data['game']['user_id'] = $this->auth->user('id');         $this->game->save($this->request->data);     } } 

but can , should done better moving logic model, remember: fat models, skinny controllers. here broken down , short example:

// controller public function add() {     if ($this->request->is('post') {        $this->game->add($this->auth->user('id'), $this->request->data);     } }  // model public function add($userid, $postdata) {         $postdata[$this->alias]['user_id'] = $userid;         return $this->save($this->request->data);     } } 

usually don't want access session directly in model because requires use static or singleton call auth component or session object, want avoid as can.
