엔티티를 제거하면 관계 OneToOne이 제거되지 않았습니다. 갤러리가 데이터베이스에서 성공적으로 제거되었지만 largeImage, mediumImage 및 smallImage는 삭제되지 않았습니다.Doctrine OneToOne 엔티티 제거
내가 뭘 잘못 했니? 컨트롤러
삭제 작업 :
이public 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'));
}

고마워요, 완벽하게 작동합니다! 하지만 한 가지 질문이 있습니다. 왜 두 번 플러시를 사용해야합니까? – psalkowski
서로 참조하므로 한 번에 둘 다 제거 할 수 없습니다. 양쪽에 외래 키가 있습니다. 먼저 한 쪽의 외래 키를 NULL로 설정 한 다음 나머지는 삭제할 수 있습니다. – jchampion
