Symfonyの関係OneToMany

Question

私はこの問題を抱えています。私はコレクションであるエンティティのための1つまたは複数の写真をアップロードしようが、私は、私はこのエラーを持っている私のフォーム提出するとき：

Symfony\Component\Validator\ConstraintViolation 
Object(Symfony\Component\Form\Form).data.imagearticle[0].Article = null

あなたの助けにはThx！

マイコントローラ：

    { 

     $article= new Article(); 
     $form = $this->get('form.factory')->create(new \AD\PlatformBundle\Form\ArticleType(), $article); 
     if($form->handleRequest($request)->isValid()) 
     { 

      $em = $this->getDoctrine()->getManager(); 
      $em->persist($article); 
      $em->flush(); 

      $request->getSession()->getFlashBag()->add('notice', 'Annonce enregistrée ! :)'); 
      return $this->redirect($this->generateUrl('va_platform_blog')); 
     } 

     return $this->render('ADPlatformBundle:Cars:newarticle.html.twig', array(
      'form' =>$form->createView(), 
     )); 
    } 

そして、私のフォームArticleType：

    } 

Answer 1

は、ソリューションです。 ImageArticle.phpで

：Article.phpで

/** 
* @var Article 
* @ORM\ManyToOne(targetEntity="AD\PlatformBundle\Entity\Article", inversedBy="imagearticle") 
* @ORM\JoinColumn(nullable=false) 
* @Assert\NotNull() 
*/ 
private $article; //previously $Article 

：画像記事を収集していないオブジェクトであるため、

/** 
* 
* @ORM\OneToMany(targetEntity="AD\PlatformBundle\Entity\ImageArticle", mappedBy="article", cascade="all", orphanRemoval=true) 
* @Assert\Valid() 
* 
*/ 
private $imagearticle; // remove @ORM\OrderBy({"position" = "ASC"}) since there is no position property 

public function __construct() 
{ 
    $this->user = new \Doctrine\Common\Collections\ArrayCollection(); 
    $this->imagearticle = new \Doctrine\Common\Collections\ArrayCollection(); //instanciate as an ArrayCollection when a new instance of Article is created 
} 

/** 
* Add imagearticle 
* 
* @param \AD\PlatformBundle\Entity\ImageArticle $imagearticle 
* 
* @return Article 
*/ 
public function addImagearticle(\AD\PlatformBundle\Entity\ImageArticle $imagearticle) 
{ 
    $imagearticle->setArticle($this); //since doctrine only checks owning side you need to do this to keep data in sync 
    $this->imagearticle[] = $imagearticle; 

    return $this; 
} 

/** 
* Remove imagearticle 
* 
* @param \AD\PlatformBundle\Entity\ImageArticle $imagearticle 
*/ 
public function removeImagearticle(\AD\PlatformBundle\Entity\ImageArticle $imagearticle) 
{ 
    $imagearticle->setArticle(); //same reason than above 
    $this->imagearticle->removeElement($imagearticle); 

    return $this; 
} 

は私も（）メソッドのsetImagearticleを削除することをお勧めします、あなたはそれを使用する必要はありません。

camelCaseを使用すると、変数とメソッドに名前を付けることができます（イメージアートではなく$ imageArticleにする必要があります）。これは他の人がコードを読みやすくするための良い方法です。

最後に、コレクションを使って作業しているとき（つまり、ユーザーではなくユーザー）に複数形を使用して、作業しているものをすぐに知ることができます。
