Doctrine orm 原则2-完整性约束违反错误

我有两个实体，产品和附属公司。我想插入新产品，但出现错误：

完整性约束冲突：1048列“affiliateId”不能为null

这是php代码：

            $affiliate = $this->_em->getRepository("Common\Entity\Affiliate")->find(1);

            $product = new Product();
            $product->setAffiliate($affiliate);
            $product->statusId = $form->getValue('statusId');
            [...]
            $product->created = new \DateTime("now");

            $this->_em->persist($product);
            $this->_em->flush();

产品实体：

<?php

namespace Common\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * A product.
 *
 * @ORM\Entity
 * @ORM\Table(name="product")
 */
class Product {

    /**
     * @ORM\Id
     * @ORM\Column(type="integer");
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    protected $id;

    /**
     * @ORM\Column(type="integer")
     */
    protected $statusId;

    /**
     * @ORM\Column(type="datetime")
     */
    protected $created;


    /**
     * @ORM\ManyToOne(targetEntity="Affiliate", inversedBy="product")
     * @ORM\JoinColumn(name="affiliateId", referencedColumnName="id")
     */
    protected $affiliate;

    public function setAffiliate($affiliate) { 
        $this->affiliate = $affiliate; 
    }

    /**
     * Magic getter to expose protected properties.
     *
     * @param string $property
     * @return mixed
     */
    public function __get($property) {
        return $this->$property;
    }


    /**
     * Magic setter to save protected properties.
     *
     * @param string $property
     * @param mixed $value
     */
    public function __set($property, $value) {
        $this->$property = $value;
    }
}

我不确定您是如何设置配置文件的，但是我已经设法让它与zend 1.10 framework一起工作，下面就是（只需更改名称空间和类引用以匹配您的名称空间和类引用，代码执行也在页面底部）
