在CakePHP3上构建查询

Question

我正在试图获得每个商店的评论数量，我真的坚持这一步 是否可以这样做，以及如何做到？

public function display()
    {


        $this->loadModel('Shops');
        $shoplist=$this->Shops->find('all')->order(['title' => 'DESC', 'id' => 'ASC'])->contain([
            'Comments' => function ($q) {
                return $q->select('id')->where(['published' => 1])->count();
            }]);;

             $this->set('shoplist', $shoplist );
    }
