我的代码出了问题。我只是想在我的数据库中插入一组简单的数据，但是doctrine将我的外键插入为NULL。
我已经转储了我的数据并发现，我的外键（adr_id）中有一些值，但是在我刷新后它被设置为NULL。
这是我的控制者：
$emblem = new Emblems();
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(new EmblemType(), $emblem);
$form->handleRequest($request);
if ( $form->isValid()) {
$attachmentArray = $form['attachment']->getData();
foreach ( $attachmentArray as $attachment ) {
if ( $attachment != NULL ) {
$random = rand(0,99999999);
$dir = $this->container->getParameter('kernel.root_dir').'/../web/uploads/embleme';
$extension = $attachment->getClientOriginalextension();
$attachment->move($dir, $random . '.' . $extension);
$image = new Images();
$image->setFotoid($random);
$image->setArticleId($emblem->getArticleId());
$image->setMimetype($extension);
$em->persist($image);
$em->flush();
}
}
$em->persist($emblem);
$em->flush();
$this->get('session')->getFlashBag()->add('notice', 'Änderungen wurden erfolgreich gespeichert!');
return $this->render('NobleBundle:Default:new.html.twig', array('form' => $form->createView()));
我的ORM映射：（注意：如果我删除＆＃34;多对一＆＃34;，它运作完美，但我没有相关实体那么......
<?xml version="1.0" encoding="utf-8"?>
<doctrine-mapping xmlns="http://doctrine-project.org/schemas/orm/doctrine-mapping" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://doctrine-project.org/schemas/orm/doctrine-mapping http://doctrine-project.org/schemas/orm/doctrine-mapping.xsd">

</many-to-one>

</doctrine-mapping>
之前我已经完成了这项工作，并且真的只是复制了我以前的代码，所以我不知道问题出在哪里。
