我试图删除一个项目在我的形式，但没有发生任何事情(甚至不是一个错误…但我可以编辑没有问题!)
我有一个嵌入3个级别的表单集合(这是关于我的网站分为子级别的法律通知)
这里是我的实体:
OneToMany中名为"MentionLegaleNv1"的第一个关卡

我的控制器:
class MentionsLegalesController extends Controller {
public function mentionLegalesAction(Request $request) {
$em = $this->getDoctrine()->getManager();
$ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv0')->findOneById(1);
if ($request->getMethod() == 'GET') {
$form = $this->createForm(new MentionLegaleNv0Type(), $ML);
}
if ($request->isMethod('POST')) {
$form = $this->createForm(new MentionLegaleNv0Type(), $ML);
$form->handleRequest($request);
if ($form->isValid()) {
$ML = $form->getData();
$em->persist($ML);
$em->flush();
return $this->redirect($this->generateUrl('administration_mentions_legales'));
}
}
return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
'form' => $form->createView(),
));
}
}
我在Symfony (http://symfony.com/doc/current/cookbook/form/form_collections.html)的CookBook中发现，我尝试了，但没有成功…
class MentionsLegalesController extends Controller {
public function mentionLegalesAction(Request $request) {
$em = $this->getDoctrine()->getManager();
$ML = $em->getRepository('Video2LearnBddBundle:MentionLegaleNv1')->findOneById(1);
foreach ($ML->getMentionsLegalesNv2() as $tag) {
$originalTags->add($tag);
}
if ($request->getMethod() == 'GET') {
$form = $this->createForm(new MentionLegaleNv1Type(), $ML);
}
if ($request->isMethod('POST')) {
$form = $this->createForm(new MentionLegaleNv1Type(), $ML);
$form->handleRequest($request);
if ($form->isValid()) {
foreach ($originalTags as $tag) {
if ($ML->getMentionsLegalesNv2()->contains($tag) == false) {
$em->persist($tag);
}
}
$em->persist($ML);
$em->flush();
return $this->redirect($this->generateUrl('administration_mentions_legales'));
}
}
return $this->render('Video2LearnAdministrationBundle:Pages:mentions_legales.html.twig', array(
'form' => $form->createView(),
));
}
}
如何删除项目在MentionLegaleNv2或MentionLegaleNv3 ??
谢谢你的帮助!
你的remove方法应该自动更新连接的对象，就像你的add方法一样。
/**
* Remove MentionsLegalesNv2
*
* @param 'Video2Learn'BddBundle'Entity'MentionLegaleNv2 $mentionsLegalesNv2
*/
public function removeMentionsLegalesNv2(MentionLegaleNv2 $mentionsLegalesNv2) {
$this->MentionsLegalesNv2->removeElement($mentionsLegalesNv2);
$mentionsLegalesNv2->setMentionLegaleNv1(null);
}
我用了另一种方法…
我做到了:
if ($form->isValid()) {
// supprime la relation entre le tag et la « Task »
foreach ($originalMentionsLegalesNv1 as $mlnv2) {
if ($MentionsLegalesNv1->getMentionsLegalesNv2()->contains($mlnv2) == false) {
$em->remove($mlnv2);
}
}
$em->persist($MentionsLegalesNv1);
$em->flush();
