我的问题是我的控制器成功完成，但是 twig/view 然后呈现空白。请求不返回 html。

我的控制器以以下方式结束：

    $logger->info('Now sending song [' . $song->getId() . ' to twig');
    return array('song'=>$song);
}

由于我没有错误，因此很难找到问题所在。我所拥有的只是来自独白的 dev.log：

[2011-10-04 07:41:03] app.INFO: Now sending song [672] to twig [] []
[2011-10-04 07:41:03] event.DEBUG: Notified event "kernel.view" to listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener::onKernelView". [] []
[2011-10-04 07:41:03] event.DEBUG: Listener "Sensio\Bundle\FrameworkExtraBundle\EventListener\TemplateListener::onKernelView" stopped propagation of the event "kernel.view". [] []

[2011-10-04 07:41:03] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bundle\WebProfilerBundle\EventListener\WebDebugToolbarListener::onKernelResponse". [] []

我认为第 3 行一定是问题所在，但我不知道这意味着什么，或者任何解决方法。

编辑：如果我更改我的控制器： - 删除 @Template() - 结束看起来像：

$logger->info('Now sending song [' . $song->getId() . '] to twig');
$content = $this->renderView('MyPadBundle:Play:index.html.twig', array('song'=>$song));
$logger->info('content rendered');
return new Response($content);

然后我的 dev.log 是：

[2011-10-04 09:42:52] app.INFO: Now sending song [189] to twig [] []
[2011-10-04 09:42:53] app.INFO: content rendered [] []

[2011-10-04 09:42:53] event.DEBUG: Notified event "kernel.response" to listener "Symfony\Bundle\WebProfilerBundle\EventListener\WebDebugToolbarListener::onKernelResponse". [] []

就像内核无法返回响应一样？

我不知道出了什么问题，但这确实解决了它：

$logger->info('Now sending song [' . $song->getId() . '] to twig');
$em->clear();
return array('song'=>$song);

应该知道这将是缺乏错误报告的教义。无论如何，该表只有 1000 行，所以不确定对于树枝来说太多处理太多了，特别是因为我只通过了一行/实体。

Have to admit I'm disappointed with doctrine; or maybe the problem lies with bad design on symfony's templating?
