Symfony 2 doctrine请求对象由Id给出空白页面

时间：2014-06-09 12:17:29

标签： database symfony doctrine fetch

在主控制器中执行简单查询时，例如：

public function newAdCreatedAction($id)
{
    $em = $this->getDoctrine()->getManager()->getRepository('websiteAdsBundle:AdsList');
    $article = $em->findById($id);

    return $this->render('websiteAdsBundle:Default:newAdCreated.html.twig',array('article'=>$article));
}

我在日志文件中有一个空白页面我收到以下消息错误（如果有帮助）：

//Bunch of kernelerrors... here and then:

我认为这与@ORM \ Join语句有关，但我无法弄清楚它是什么。 我想有双向关联，Twig的转储无法正常工作

2 个答案:

答案 0 :(得分：0)

中介回答： 现在我正在使用

\Doctrine\Common\Util\Debug::dump($article);

为了获得没有问题的输出。显然有一些扩展允许以更恰当的方式回显输出。

如果我找到更好的东西，我会回来发布。

答案 1 :(得分：0)

如果您最终使用Symfony 2.6+，请确保在AppKernel.php中注册DebugBundle 

public function registerBundles()
{
    //...

    if (in_array($this->getEnvironment(), array('dev', 'test'))) {
        $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
        // ...
    }

    return $bundles;
}
