期待値「SourcingBundle \エンティティ\ RequestForEstimate」

Question

私は次のエラーを取得する：

Expected value of type "SourcingBundle\Entity\RequestForEstimate" for association field "SourcingBundle\Entity\RequestForEstimateDetail#$detail", got "Doctrine\Common\Collections\ArrayCollection" instead.

私は複数のRequestForEstimateDetailsノードを有することができるRequestForEstimate実体がある構造を作成しようとしています。 RequestForEstimateDetails内の各行は、RequestForEstimateが共通情報のみの場合、異なる製品とその詳細の要求を持つだけです。私はSymfonyを初めて使っています。私はDB内の子供たちと一緒に親要素を保存したいところで苦労しています。私はこのsymfonyのチュートリアルを次されています。ここではHow to Embed a Collection of Forms

Answer 1

フィールド詳細のゲッター/セッターメソッドは、（アド/方法は、コレクションの単一の要素のためのものである削除）ので、変更されていますgetter/setterメソッドを使用してArrayCollectionオブジェクトを処理します。例として

：

RequestForEstimateDetail

/** 
* Set detail 
* 
* @param \Doctrine\Common\Collections\ArrayCollection an array of $detail 
* 
* @return RequestForEstimateDetail 
*/ 
public function setDetail(\Doctrine\Common\Collections\ArrayCollection $detail = null) 
{ 
    $this->detail = $detail; 

    return $this; 
} 

/** 
* Get detail 
* 
* @return \Doctrine\Common\Collections\ArrayCollection 
*/ 
public function getDetail() 
{ 
    return $this->detail; 
} 

・ホープ、このヘルプ

Answer 2

はまあ、RequestForEstimateエンティティ内の既存のaddDetail方法は、トリックをした：

public function addDetail(\SourcingBundle\Entity\RequestForEstimateDetail $detail) 
{ 
    $this->details->add($detail); 
    $detail->setDetail($this); 
    return $this; 
}
