Relationships between Models

Hi all

The model "users" hasmany "posts".

The model "posts" belongTo "users".

 class Users extends \Phalcon\Mvc\Model{
    public $id;

    public $name;
    ---------------
    public function initialize(){
      $this->hasMany('id', 'Phalconvn\Models\Posts', 'userId', array(
            'alias' => 'posts',
            'foreignKey' => array(
                'message' => 'User cannot be deleted because article has not for '
            )
        ));
    }

}

class Posts extends \Phalcon\Mvc\Model{
   public $id;
   public $userId;
------------
   public function initialize(){
        $this->belongsTo('userId','Phalconvn\Models\Users','id',array(
            'alias' => 'userPost'
        ));

}
}

When login users with id does not ownership id by posts, but delete post not ownership it is wordking, why is that
