Question

我对教义queryBuilder有问题。我有两个实体：捐赠和捐赠者。我只想做一个左联接（例如，因为Donations.donorId指的是Donateurs.id。）

关于DonationsRepository的查询：

public function showAll()
    {
        $qb = $this->createQueryBuilder('dr')
            ->select('dr, dn')
            ->leftJoin('dr.donateurs','dn')
            ->getQuery()
            ->execute();

        return $qb;
    }

调用我的Controller.php

public function don(DonationsRepository $repo, Request $request)
    {
        $qb = $repo->showAll();
        var_dump($qb);

        // Then return to Twig
    }

这是一个var_dump样本：

array (size=14)
  0 => 
    object(App\Entity\Donations)[989]
      private 'id' => int 197
      private 'movement' => string 'D' (length=1)
      private 'departDate' => 
        object(DateTime)[885]
          public 'date' => string '2023-11-18 00:00:00.000000' (length=26)
          public 'timezone_type' => int 3
          public 'timezone' => string 'Europe/Paris' (length=12)
      private 'certifDate' => 
        object(DateTime)[993]
          public 'date' => string '2023-11-18 00:00:00.000000' (length=26)
          public 'timezone_type' => int 3
          public 'timezone' => string 'Europe/Paris' (length=12)
      private 'certifRef' => string 'EO62' (length=4)
      private 'productName' => string 'Clémentines' (length=12)
      private 'donorId' => int 1
      private 'family' => string 'Frais' (length=5)
      private 'recipient' => string 'EO62' (length=4)
      private 'carrierId' => int 3
      private 'nbPallet' => int 33
      private 'weight' => int 19720
      private 'billDate' => 
        object(DateTime)[891]
          public 'date' => string '2023-11-18 00:00:00.000000' (length=26)
          public 'timezone_type' => int 3
          public 'timezone' => string 'Europe/Paris' (length=12)
      private 'billReceptionDate' => 
        object(DateTime)[992]
          public 'date' => string '2023-11-18 00:00:00.000000' (length=26)
          public 'timezone_type' => int 3
          public 'timezone' => string 'Europe/Paris' (length=12)
      private 'billSentValidationDate' => 
        object(DateTime)[991]
          public 'date' => string '2023-11-18 00:00:00.000000' (length=26)
          public 'timezone_type' => int 3
          public 'timezone' => string 'Europe/Paris' (length=12)
      private 'billReference' => string '23-11-18' (length=8)
      private 'price_HT' => int 11
      private 'donateurs' => null

所有数据仅来自我的捐赠实体...。但是，如果我从存储库中删除了execute()，并且从我的控制器中执行了$qb->execute ... var_dump返回了类似的内容（这是一个示例，转储会很大）

var_dump($qb)：

public 'declaringClasses' => 
        array (size=32)
          'id_0' => string 'App\Entity\Donations' (length=20)

          'prospector_adviser_31' => string 'App\Entity\Donateurs' (length=20)

这两个实体似乎映射在正确的字段上！但是现在，我无法发送给树枝，在我看来，所有内容都是空的（没有错误消息）。

自3天以来，这使我有点疯狂。请帮忙，对不起我的英语。

更新实体。

Answer 1

您只需要向属性donateurs添加访问器

/**
 * @ORM\ManyToOne(targetEntity="App\Entity\Donateurs", inversedBy="donations")
 */
private $donateurs;

public function getDonateurs()
{
    return $this->donateurs;
}

public function setDonateurs($donateurs)
{
    $donateurs = $this->donateurs;

    return $this;
}

应该可以解决您的问题

编辑：

您也应该在donations实体中为Donateur属性添加getter和setter。

解决“ showAll”问题的另一种方法是使用主义的存储库方法：

// You should suffix any action of your controller with "Action"
public function donAction(DonationsRepository $repo, Request $request)
{
    $results = $repo->findAll(); //
    var_dump($results);

    // Then return to Twig
}

您可以通过执行以下操作来访问树枝中的donateurs：

{{ donation.donateurs }}

通过保留您的方法，如果尝试通过在存储库方法中进行操作来强制关联的水合作用，会发生什么情况：

public function showAll()
{
    $results = $this->createQueryBuilder('dr')
        ->select('dr, dn')
        ->leftJoin('dr.donateurs','dn')
        ->getQuery()
        ->execute([], Query::HYDRATE_OBJECT);

    return $results;
}

如果这仍然不起作用，您确定在数据库donateur_id中有donation并在donateur表中有相应的行吗？ >
