Symfony：學說不更新ManyToOne

當我嘗試添加一個對象從我的實體'Facture'主義不更新對象'Dechet'。插入工作正常，但在我的表Dechet我沒有從我的對象（Facture）我的外鍵：Symfony：學說不更新ManyToOne

    if($dechetVert>$CorrecteurDechetVert || $Encombrants>$CorrecteurEncombrants || $Bois>$CorrecteurBois || 
        $Brique>$CorrecteurBrique || $Terre>$CorrecteurTerre) { 
        $time = new \DateTime('now'); 
        $Facture = new Facture(); 
        $Facture->setDate($time); 
        $Facture->setStatut('Impayé'); 
        $repository = $em->getRepository('Bundles\UserBundle\Entity\User'); 
        $menage = $repository->findOneById($UserId); 
        $repository = $em->getRepository('Bundles\MainBundle\Entity\TypeDechet'); 
        $type =$repository->findBy(array('Nom'=>$Type)); 
        $repository = $em->getRepository('Bundles\MainBundle\Entity\Dechet'); 
        $DechetsSelectionne = $repository->getDechetByMenageAndType($menage,$type); 
        $Facture->setUtilisateur($menage); 
        $Facture->setDechets($DechetsSelectionne);

首先確認你getDechetByMenageAndType有一個結果，假設你在下面。

我看到的主要問題是您指定Facture::$Dechets爲OneToMany這意味着Dechets是對象的集合（多個）。

所以你需要改變以下內容。

namespace Bundles\MainBundle\Entity; 

use Doctrine\Common\Collections\ArrayCollection; 
use Doctrine\DBAL\Types\IntegerType; 
use Doctrine\ORM\Mapping as ORM; 

/** 
* Facture 
* 
* @ORM\Table(name="facture") 
* @ORM\Entity() 
*/ 
class Facture 
{ 
    //... 
    /** 
    * @var ArrayCollection|\Bundles\MainBundle\Entity\Dechet[] 
    * @ORM\OneToMany(
    * targetEntity="Bundles\MainBundle\Entity\Dechet", 
    * mappedBy="Facture", 
    * cascade={"all"} 
    *) 
    */ 
    private $Dechets; 

    //... 

    public function __construct() 
    { 
     $this->Dechets = new ArrayCollection(); 
    } 

    /** 
    * @return ArrayCollection|\Bundles\MainBundle\Entity\Dechet[] 
    */ 
    public function getDechets() 
    { 
     return $this->Dechets; 
    } 

    /** 
    * @param \Bundles\MainBundle\Entity\Dechet $Dechets 
    */ 
    public function addDechet(\Bundles\MainBundle\Entity\Dechet $Dechets) 
    { 
     if (!$this->Dechets->contains($Dechets)) { 
      $Dechets->setFacture($this); //explicitly set the facture 
      $this->Dechets[] = $Dechets; 
     } 

     return $this; 
    } 

    /** 
    * @param \Bundles\MainBundle\Entity\Dechet $Dechets 
    */ 
    public function removeDechet(\Bundles\MainBundle\Entity\Dechet $Dechets) 
    { 
     if ($this->Dechets->contains($Dechets)) { 
      $Dechets->setFacture(null); //optional if Facture is nullable 
      $this->Dechets->removeElement($Dechets); 
     } 

     return $this; 
    } 
}

然後在你的控制器改變$Facture->setDechets($DechetsSelectionne);到

$Facture->addDechet($DechetsSelectionne);

如果您提交收集與getDechetByMenageAndType，你將需要申請的骨折。

所以，你可以做

foreach($DechetsSelectionne as $Dechet) { 
    $Facture->addDechet($Dechet); 
}

下，如果在dechet數據庫表中的關聯字段是不是Facture_id你需要用JOIN column定義擁有方列。假設列名Facture你可以使用：

namespace Bundles\MainBundle\Entity; 

use Doctrine\ORM\Mapping as ORM; 


/** 
* Dechet 
* 
* @ORM\Table(name="dechet") 
* @ORM\Entity(repositoryClass="Bundles\MainBundle\Entity\DechetRepository") 
*/ 
class Dechet 
{ 
    //... 

    /** 
    * @ORM\ManyToOne(
    * targetEntity="Bundles\MainBundle\Entity\Facture", 
    * inversedBy="Dechets", 
    *) 
    * @ORM\JoinColumn(name="Facture", referencedColumnName="id", nullable=true) 
    */ 
    private $Facture; 

}

進行更改後，一定要清除緩存

php bin/console cache:clear --no-warmup 
php bin/console cache:warmup

getDechetByMenageAndType Works我嘗試過。我有這個例外：嘗試從命名空間「Bundles \ MainBundle \ Entity」加載類「ArrayCollection」。您忘記了「Doctrine \ Common \ Collections \ ArrayCollection」的「使用」語句嗎？ –

您必須在我的示例中添加'使用Doctrine \ Common \ Collections \ ArrayCollection'到您的'Facture'實體的頂部。 – fyrye

感謝您的回覆，我添加了它，但現在出現此錯誤： –

我想你忘記添加

$dechetSelectionne->addFacture($Facture)

在實體另外補充：

/** 
* @ORM\ManyToOne(
* targetEntity="Bundles\MainBundle\Entity\Facture", 
* inversedBy="Dechets", cascade={"persist"} 
*) 
*/ 
private $Facture;

當我做到這一點，我有： –

一個新的實體是通過關係找到'Bundles \ MainBundle \ Entity \ Dechet＃Menage'未配置爲級聯實體：scadra-08的持久化操作。要解決這個問題：顯式調用EntityManager＃persist（）這個未知的實體或配置級聯在映射中堅持這個關聯，例如@ManyToOne（..，cascade = {「persist」}） –

你必須在齊平。如果仍然無效嘗試（仍然在刷新後）'$ Facture-> getId（）;' –
