原则2中的一对多关系ORM不插入远程键

大家好!

我在一些原则2的关系上遇到了问题，这些关系目前使我陷入困境。

我正试图在我的AnalyticsCampaign模型和我的AnalyticsData模型之间建立一个非常好的和简单的一对多关系。

下面是我的代码和我的问题。

foreach($entries as $entry)
{
    // Instance of AnalyticsCampaign model with data in it.
    $campaign = $this->_getCampaignByGoogleId($entry['campaignId']);            
    $daysAgo = time() - $campaign->getUpdated();
    $dateCreated = time() - $campaign->getCreated();
    if($daysAgo>=86400 || $dateCreated < 86400)
    {
        // More or equal to 1 day has passed since last database update
        // Let's insert these fuckers.
        // Insert the new GA data.
        $data = new Model_AnalyticsData();
        $data->fromArray($entry);
        $data->setCampaign($campaign->getId());
        $campaign->data = array($data);
        $this->em->persist($campaign);
    }
}
$this->em->flush();

Analytics Campaign data

AnalyticsData模型

class Model_AnalyticsData

    public function __construct()
    {

        $this->created = $this->updated = time();
    }

    private $updated;
    /**

     */
    protected $campaign;

    public function fromArray(array $array)
    {
        $objects = get_object_vars($this);
        foreach($array as $item => $value)
        {
            if(array_key_exists($item, $objects))
            {
                $this->$item = $value;
            }
        }
    }
    /**

    public function updated()
    {
        $this->updated = time();
    }
    public function setCampaign($id)
    {
        $this->campaign = $id;
    }

}

我遇到的问题是，它确实添加了子表数据没有问题，但它没有填写我的竞选id字段，这是在AnalyticsData。

当我手动尝试设置ID时，它会显示:

有没有人见过这个，如果有，我到底做错了什么?

非常感谢，我将给100万互联网的人可以帮助!
