在 CakePHP3 中构建查询

Question

我正在尝试获取每个商店的评论数，但我真的卡在了这一步。
有没有可能，怎么做？

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 );
    }
