manyToMany の一方的な関係を持つ Quiz と QuizQuestion という 2 つのエンティティがあります。クイズフォームに質問フォームを埋め込みたいです。私は2.0ブランチにいます。ドロップダウンでIDのリストを取得sonata_type_modelし、「追加」ボタンを操作して、作業に取り掛かることができます。ただし、使用しようとするとエラーが発生しますsonata_type_admin：

Neither property "title" nor method "getTitle()" nor method "isTitle()" exists in class "Doctrine\ORM\PersistentCollection"

quizQuestion をサービス登録しようとしたのですが、Expected argument of type "Festus\SiteBundle\Entity\QuizQuestion", "Doctrine\ORM\PersistentCollection" given 500 Internal Server Error - UnexpectedTypeException

数時間調べても解決策が見つかりませんでした...

わかりました、これを置き換えて解決しました：

->add('questions', 'sonata_type_admin', array(), array('required' => false, 'edit' => 'inline'));

これとともに：

->add('questions','collection', array( 'type' =>  new QuizQuestionType(),
                                          'allow_add' => true,
                                          'prototype' => true,
                                          'by_reference' => true,
                                          ));

しかし、私にとっては、解決策というよりも回避策のように見えます:-|

とにかく、バンドルのバージョン、symfony ブランチをチェックしましたが、一貫性のないものは何も見つかりませんでした。すべてが 2.0 ブランチにあります。

エラーは、存在しないメソッドの例外が発生する理由を説明しているようです。

オブジェクトの代わりにコレクションを渡そうとしています。おそらく、コレクションからのオブジェクトではなく、コレクションへの呼び出しaddQuestion()またはメソッドです。setQuestion()

これは通常、リレーションが設定されたオブジェクトで発生します。

そのメソッドを使用する場所では、$object->first()->addQuestion()代わりに呼び出すようにしてください$object->addQuestion()
