我遇到了一个 Doctrine ORM 查询错误，我确信它是一个非常简单的修复，但我还不了解 symfony2 中的所有内容：) 我进行了数小时的搜索，但我自己找不到解决方案。

Notice: Undefined index: id_chapter in C:\xampp\htdocs\vendor\doctrine\orm\lib
\Doctrine\ORM\Internal\Hydration\ObjectHydrator.php on line 93

Notice: Undefined index: id_book in C:\xampp\htdocs\vendor\doctrine\orm\lib

Fatal error: Call to a member function getValue() on a non-object in C:\xampp\
htdocs\vendor\doctrine\orm\lib\Doctrine\ORM\Internal\Hydration\ObjectHydrator
.php on line 371

这些通知似乎与我的映射错误有关，这里是我的实体构建的一部分

/**
 * @ORM\ManyToOne(targetEntity="testament", inversedBy="books")
 * @ORM\JoinColumn(name="id_testament", referencedColumnName="id_testament")
 */
 protected $testament;

如果需要，请询问更多详细信息，任何帮助将不胜感激！谢谢。

编辑：添加这段代码可能很有用

$em = $this->getDoctrine()->getManager();
        $rsm = new ResultSetMappingBuilder($em);
        $rsm->addRootEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\line', 'l');
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\livreChapitre', 'c', 'l', 'id_chapter', array('id_chapter' => 'idc'));
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\book', 'b', 'c', 'id_book', array('id_book' => 'idb'));
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\testament', 't', 'b', 'id_testament', array('id_testament' => 'idt'));

        $sql = 'SELECT t.id_testament, b.book_number, c.chapter_wording, l.line_number, l.line_content FROM line l INNER JOIN chapter c ON l.id_chapter = c.id_chapter 
                    INNER JOIN book b ON c.id_book = b.id_book 
                    INNER JOIN testament t ON b.id_testament = t.id_testament 
                    WHERE MATCH (line_content) AGAINST (:request) LIMIT 0,75';

        $query = $em->createNativeQuery($sql, $rsm);
        $query->setParameter('request', $request);

        $lines = $query->getResult();

这是我的新代码，处理 id 冲突问题：

$em = $this->getDoctrine()->getManager();
        $rsm = new ResultSetMappingBuilder($em);
        $rsm->addRootEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\line', 'l', array('id' => 'lid'));
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\livreChapitre', 'c', 'l', 'id_chapter', array('id_chapter' => 'idc'));
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\book', 'b', 'c', 'id_book', array('id_book' => 'idb'));
        $rsm->addJoinedEntityFromClassMetadata('dieuenligne\websiteBundle\Entity\testament', 't', 'b', 'id_testament', array('id_testament' => 'idt'));

$sql = 'SELECT t.id, b.book_number, c.chapter_wording, l.line_number, l.line_content FROM line l INNER JOIN chapter c ON l.id_chapter = c.id 
                    INNER JOIN book b ON c.id_book = b.id 
                    INNER JOIN testament t ON b.id_testament = t.id 
                    WHERE MATCH (line_content) AGAINST (:request) LIMIT 0,75';

这是我的遗嘱实体的一部分：

class testament
{
/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
private $id;

/**
 * @var integer
 *
 * @ORM\Column(name="id_bible", type="integer").
 */
private $idBible;

/**
 * @var string
 *
 * @ORM\Column(name="testament_wording", type="string", length=20)
 */
private $testamentWording;

/**
 * @ORM\ManyToOne(targetEntity="bible", inversedBy="testaments")
 * @ORM\JoinColumn(name="id_bible", referencedColumnName="id")
 */
protected $bible;

/**
 * @ORM\OneToMany(targetEntity="book", mappedBy="testament")
 * @ORM\OrderBy({"bookNumber" = "ASC"})
 */
protected $books;

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

这是我的错误：

The column 'id' conflicts with another column in the mapper. 

at ResultSetMappingBuilder ->addAllClassFields ('dieuenligne\websiteBundle\Entity\book', 'b', array('id_book' => 'idb'))
in C:\xampp\htdocs\vendor\doctrine\orm\lib\Doctrine\ORM\Query\ResultSetMappingBuilder.php at line 71  +
at ResultSetMappingBuilder ->addJoinedEntityFromClassMetadata ('dieuenligne\websiteBundle\Entity\book', 'b', 'c', 'id_book', array('id_book' => 'idb'))
in C:\xampp\htdocs\src\dieuenligne\websiteBundle\Controller\WebsiteController.php at line 112  +

我正在努力，如果解决了我会更新。我之前遇到过这个错误，我在 中添加了 array('id_chapter' => 'idc')，addJoinedEntityFromClassMetadata但这似乎不是这里的解决方案。

我没有在文档中找到解决方案。我尊重大多数约定，但我仍然有一个身份问题（似乎是这样）。

我应该显示我的代码的更大部分吗？

仍然坚持这一点，这是ResultSetMappingBuilder.php at line 71

public function addJoinedEntityFromClassMetadata($class, $alias, $parentAlias, $relation, $renamedColumns = array())
{
    $this->addJoinedEntityResult($class, $alias, $parentAlias, $relation);
    $this->addAllClassFields($class, $alias, $renamedColumns);
}

71 号线在addAllClassFields. 对我来说，类、别名和重命名的列都很好，因为我使用的是重命名的列属性 ( array('id_book' => 'idb'))，所以我不应该有 id 冲突......

提前感谢您对此的任何建议，这是我在 symfony 上的第一个项目，同时也是网络开发的初学者，所以我真的需要帮助！:)

不确定，因为我没有看到您的代码的其他部分，但如果您的实体命名Testament和引用的列名是id：

 /**
 * @ORM\ManyToOne(targetEntity="Testament", inversedBy="books")
 * @ORM\JoinColumn(name="id_testament", referencedColumnName="id")
 */
 protected $testament;
