我正在尝试创建两个实体之间的OneToOne单向关系。我已经创建了模式，但是当我提交表单时，它没有将数据持久化到集合中。根据我所有的研究，我怀疑这是因为我没有正确设置拥有的实体，但我已经尝试了所有我能找到的方法，但没有运气。

由于这让我很伤心，我决定在与sshaun和ddproxy一起工作后，在官方#symfony irc频道中发布我的答案。
首先，我确实把所有权关系搞错了。需要将逆函数切换到product.php。其次，我需要保存数据，所以我将下面的内容添加到控制器中，瞧，就像变魔术一样，它起作用了。
if ($form->isValid()) {
$date = new DateTime('NOW');
$product->setUpdateDate($date);
$em->persist($product);
$em->flush();
$description = $product->getDescription()->first();
$description->setProductId($product);
$em->persist($description);
$em->flush();
return $this->redirect($this->generateUrl('scw_designs_admin_products'));
}
