Symfony 3.2 Crash with Error＆＃39; vendor / doctrine / dbal / lib / Doctrine / DBAL / Driver / PDOStatement.php on 91＆＃39;

Question

我不知道为什么，但是当我从symfony应用程序查看一个页面时，它崩溃了这个错误：Symfony 3.2 Crash with Error＆＃39; vendor / doctrine / dbal / lib / Doctrine / DBAL /第91行＆＃39;上的Driver / PDOStatement.php。它并不是一个非常复杂的页面，而且以前工作得很好。

控制器：

    public function showAction($motorId)
{
    $em = $this->getDoctrine()->getManager();
    $motor = $em->getRepository('AppBundle:motors')
        ->findOneBy(['id' => $motorId]);

    if (!$motor) {
        throw $this->createNotFoundException('motor not found');
    }
    $motorImage = $motor->getImageName();

    return $this->render('motors/motorView.html.twig', array(
        'm' => $motor,
        'image' => $motorImage
    ));

}

树枝模板：

{% extends 'base.html.twig' %}

{% block body %}

    <div class="row">
        <!-- Motors -->
        {% if m.make is not empty %}
            <div class="col-sm-6">

有趣的是，它只是导致问题的一个项目。这是转储信息：

    motors {#1860 ▼
  -id: 10
  -make: "Yamaha"
  -hp: "250"
  -year: "2012"
  -model: "f250txr"
  -serial: "yamahaserial123"
  -cycle: "4"
  -motorCondition: "Like New"
  -motorCategory: "Outboard"
  -details: null
  -shaft: "25"
  -rotation: "Standard"
  -compression: "180, 180, 180, 180, 180, 180"
  -price: null
  -owner: "Banana Monster"
  -customer: customers {#1936 ▶}
  -createdBy: "keyboard smasher"
  -purchasePrice: "5000"
  -dateAcquired: DateTime {#1856 ▼
    +"date": "2017-06-01 00:00:00.000000"
    +"timezone_type": 3
    +"timezone": "America/New_York"
  }
  -mStatus: null
  -imageFile: null
  -imageName: null
  -updatedAt: DateTime {#1857 ▶}
  -onBoat: 0
  -boat: PersistentCollection {#1928 ▶}
  -saleItem: PersistentCollection {#2000 ▶}
  -boats: null

这是用于比较的另一个：

 motors {#573 ▼
  -id: 5
  -make: "Yamaha"
  -hp: "250"
  -year: "2005"
  -model: "F250TXR"
  -serial: "YMS102RL192"
  -cycle: "4"
  -motorCondition: null
  -motorCategory: "Outboard"
  -details: null
  -shaft: "25"
  -rotation: null
  -compression: null
  -price: null
  -owner: "Banana Bandit"
  -customer: null
  -createdBy: "keyboard smasher"
  -purchasePrice: null
  -dateAcquired: null
  -mStatus: null
  -imageFile: null
  -imageName: null
  -updatedAt: DateTime {#570 ▶}
  -onBoat: 0
  -boat: PersistentCollection {#582 ▶}
  -saleItem: PersistentCollection {#703 ▶}
  -boats: null

任何想法会使这个特定项目如此合适？

Answer 1

试试这个：

$motor = $em->getRepository('AppBundle:motors')
        ->find($motorId);

而不是：

$motor = $em->getRepository('AppBundle:motors')
        ->findOneBy(['id' => $motorId]);
