Doctrine/Symfony - 继承 - 关系

我有两个实体：Individu（个人）和 Epoux_se（丈夫） Husband extends Individual

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();
}

和班夫

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

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

我对丈夫的构造函数有错误

SQLSTATE[42S22]：未找到列：1054 未知列“字段列表”中的“pere_id”

执行'INSERT INTO epoux_se (nom, prenoms, sexe,professional, pere_id, mere_id,lieu Origine, dateNaissance, age) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?)'时发生异常使用参数 ["Aurel", "a:2:{i:0;s:15:\"Jean-Christ ophe\";i:1;s:4:\"Marc\";}", "M" ，空，空，空，“圣马洛”，“05/08/1722”，22]：

灯具：

$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(); 

怎么做 ？谢谢 ！
