JOIN 的 QueryBuilder 问题

Question

我对 Doctrine queryBuilder 有疑问。 我有两个实体：捐赠和捐赠者。我只想做一个左连接（例如，因为 Donations.donorId 指的是 Donateurs.id。）

DonationsRepository 上的查询：

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 示例：

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.... 但是如果我从我的存储库中删除execute()，然后我从我的控制器中执行$qb->execute...var_dump 向我返回类似的东西（这是一个示例，转储很大）

var_dump($qb)：

public 'declaringClasses' => 
        array (size=32)
          'id_0' => string 'App\Entity\Donations' (length=20)
          'movement_1' => string 'App\Entity\Donations' (length=20)
          'depart_date_2' => string 'App\Entity\Donations' (length=20)
          'certif_date_3' => string 'App\Entity\Donations' (length=20)
          'certif_ref_4' => string 'App\Entity\Donations' (length=20)

          'dpt_23' => string 'App\Entity\Donateurs' (length=20)
          'product_24' => string 'App\Entity\Donateurs' (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，我无法发送到树枝，在我看来一切都是空的（没有错误消息）。

这让我从 3 天开始就疯了。 需要帮助，对不起我的英语。

更新 实体。

Answer 1

您只需将访问器添加到属性donateurs

/**
 * @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;
}

应该能解决你的问题

编辑：

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

解决“showAll”问题的另一种方法是使用学说的存储库方法：

// 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
}

您可以通过以下方式访问您的树枝中的donateurs：

{{ donation.donateurs }}

通过保留您的方法，如果您尝试通过在存储库方法中执行操作来强制关联水合会发生什么：

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，您确定在您的数据库中有一个 donateur_id 在您的 donation 行和您的 donateur 表中的相应行吗？
