私は zend フレームワークが初めてで、関係のある本から著者を取得する際に問題があります: 致命的なエラー: E:\xampp\htdocs\quickstart\ の非オブジェクトでメンバー関数 findParentRow() を呼び出します14 行目の application\controllers\BookController.php

クラスを配置しましたが、目標は、著者と本の間に 1,n の関係を持つアプリを作成することです

私は以前に yii フレームワークを使用していましたが、その違いは本当に大きいです。ご協力いただきありがとうございます

私はそれが正しいタイプ (Zend_Db_Table_Row_Abstract) であるかどうかをテストしました。

$book = new Application_Model_BookMapper();

    //$name = $t->findParentRow('Application_Model_DbTable_Book');
    $this->view->entries = $book->fetchAll();//findAuteur(1,new Application_Model_Book());
    foreach ($this->view->entries as $b){
        echo gettype($b)."&&class=".get_class($b);
        if ($b instanceof Zend_Db_Table_Row_Abstract) {
            echo 'okkk';
        }
        //$name = $b->findParentRow('Application_Model_DbTable_Auteur');//findDependentRowset
    }
