当我删除实体时，关系 OneToOne 没有被删除。图库已成功从数据库中删除，但 largeImage、mediumImage 和 smallImage 没有。
我做错了什么？
删除控制器中的操作：
public function deleteAction($id)
{
$em = $this->getDoctrine()->getManager();
$offer = $em->getRepository('ToCmsBundle:Offer')->find($id);
if($offer) {
if(!$offer->getGallery()->isEmpty()) {
foreach($offer->getGallery() as $key => $image) {
$image->setOffer(null);
$offer->removeGallery($image);
//$em->remove($image);
//$em->flush();
echo $image->getPath() . '<br/>';
}
} else {
echo 'gallery is empty';
}
$offer->setLargeImage(null);
$offer->setMediumImage(null);
$offer->setSmallImage(null);
$em->remove($offer);
$em->flush();
}
return $this->redirect($this->generateUrl('to_offer_list'));
}
