Doctrine/Symfony - 继承 - 关系

Question

我有两个实体：Individu（个人）和 Epoux_se（丈夫）丈夫继承个人

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

/**
 * @var string
 *
 * @ORM\Column(name="nom", type="string", length=30)
 */
private $nom;

/**
 * @ORM\OneToOne(targetEntity="AppBundle\Entity\Individu", cascade={"persist"})
 * @ORM\JoinColumn(name="pere_id", referencedColumnName="id", onDelete="CASCADE")
 */
private $pere;

public function __construct($nom, $prenoms, $sexe)
{
    $this->nom = $nom;
    $this->prenoms= $prenoms;
    $this->sexe = $sexe;
    $this->actes = new \Doctrine\Common\Collections\ArrayCollection();
}

还有class老公

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

public function __construct($nom, $prenoms, $sexe, $lieuOrigine, $dateNaissance, $age)
{
    parent::__construct($nom, $prenoms, $sexe);
    $this->lieuOrigine = $lieuOrigine;
    $this->dateNaissance = $dateNaissance;
    $this->age = $age;
}

当我导入 DataFixtures 时

new Epoux_se("Aurel", ["Jean-Christophe", "Marc"], "M", "Saint-Malo", "05/08/1722", 22);

我对 Husband 的构造函数有错误

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'pere_id' in 'field list'

An exception occurred while executing 'INSERT INTO epoux_se (nom, prenoms, sexe, profession, pere_id, mere_id, lieu Origine, dateNaissance, age) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)' with params ["Aurel", "a:2:{i:0;s:15:\"Jean-Christ ophe\";i:1;s:4:\"Marc\";}", "M", null, null, null, "Saint-Malo", "05/08/1722", 22]:

赛程：

$marie = new Individu("Duhamel", ["Ophelia", "Carmène"], "F"); 
$manager->persist($marie); 
$epoux_se = new Epoux_se("Aurel", ["Jean-Christophe", "Marc"], "M", "Saint-Malo", "05/08/1722", 22); 
$manager->persist($epoux_se); 
$manager->flush();

怎么办？谢谢！

Answer 1

将父 class 属性的可见性更改为受保护。然后更新你的数据库方案。

Answer 2

我找到了解决办法！ Individual Entity

上面需要添加如下注解

@ORM\InheritanceType("JOINED")

/**
* Individu
*
* @ORM\InheritanceType("JOINED")
*
* @ORM\Entity(repositoryClass="AppBundle\Repository\IndividuRepository")
*/
class Individu
