Symfony 提交按钮没有正确 flush/update 实体

Question

我的实体 "corporation" 与

有两个 ManyToMany 关系

实体 "User" 和
实体"Agency"

相关数据，我想显示为 table，带有指向 (un-)select 数据的 EntityType 下拉列表。因此我有以下形式：

$builder
    ->add('usercorporations', EntityType::class, array(
      'class' => 'UserBundle:User',
      'query_builder' => function (EntityRepository $er) use ($corporationMarket) {
        return $er->createQueryBuilder('e')
        ->andWhere(':marketIds MEMBER OF e.markets')
        ->setParameter('marketIds',$corporationMarket)
        ->orderBy('e.lastName', 'ASC');
      },
      'choice_label' => function($user) {
        return $user->getFirstName() . ' ' . $user->getLastName() ;
      },
      'expanded' => false, 'multiple' => true,
      'required'=>false,
      'by_reference' => false,
      'empty_value' => "label.select_user",
      'translation_domain' => 'Agency'))

  ->add('agencies', EntityType::class, array(
   'class' => 'AppBundle:Agency',
   'query_builder' => function (EntityRepository $er){
   return $er->createQueryBuilder('a')
   ->addOrderBy('a.account', 'ASC');
   },
   'label' => 'label.agencies',
   'choice_label' => function($agency) {
     return $agency->getId() . ' - ' . $agency->getAccount() . ' - ' . $agency->getCityName() . ', ' . $agency->getState();
   },
   'expanded' => false, 'multiple' => true,
   'required' => false,
   'translation_domain' => 'Agency',
  ));

我的树枝模板包括两个下拉菜单以及每个实体的两个 table。

      {{ form_start(form) }}
  {# This renders a red banner if the form contains errors.
    If the form variable is not called "form", pass it explicitly. #}
  {% include 'Form/form_errors_banner.html.twig' %}
  <div class="row">
    <div class="col-md-12">
      <div class="panel panel-default">
        <div class="panel-body">
          <legend>{{ 'label.assignedUsers'|trans }}</legend>
          {{ form_widget(form.usercorporations) }}
          <br>
          <br>
          {% include 'UserBundle:User:AssignedUsers.html.twig' %}
        </div>
      </div>
    </div>
    <div class="col-md-12">
      <div class="panel panel-default">
        <div class="panel-body">
          <legend>{{ 'label.assignedAgencies'|trans }}</legend>
          {{ form_widget(form.agencies) }}
          <br>
          <br>
          {% include 'AppBundle:Agency:AssignedAgencies.html.twig' with {'entity': corporation} %}
        </div>
      </div>
    </div>
    <div>
      <input type="submit" class="btn-primary btn" value="{{ 'label.apply'|trans }}"/>
    </div>
    {{ form_end(form) }}

  </div>

我也在其他页面上使用 tables（AssignedUsers 和 AssignedAgencies），一切正常。

所以现在我的问题是：我希望能够简单地添加和删除用户或代理机构。通过 deselecting 例如下拉列表中的用户然后提交，它正在工作，用户不再分配给公司。不知何故，同样的程序对这些机构不起作用。我不知道为什么，我在刷新之前和之后转储了数据并且它正在转储正确的数据，但是当我 return 到公司时，没有任何改变。我的控制器操作：

/**
 * @Route("/corporation/{id}/{page}", name="appBundle_corporation", requirements={"id" = "\d+",  "page" = "\d+"}, defaults={"page" = 1}))
 */
public function corporationAction($id, Request $request, $page)
{
  $repository = $this->getDoctrine()
    ->getRepository('AppBundle:Corporation');
  $em = $this->getDoctrine ()->getManager ();
  $corporation = $repository->findOneById($id);
  /*
  * CREATE PAGINATION FOR TABLES
  */
  //assigned Users
  $assignedUsers = $corporation->getUsercorporations();

  $assignedAgencies = $corporation->getAgencies();

  dump($assignedAgencies);

  $form = $this->createForm(CorporationAssignmentType::class,$corporation, array(
    'corporationMarket' => $corporationMarket,
  ));
  $form->handleRequest($request);

  if ($form->isSubmitted() && $form->isValid()) {
    $em->persist($corporation);
    $em->flush();
  dump($assignedAgencies);
    $this->addFlash(
      'success',
      'Your changes were saved!'
    );
    return $this->redirectToRoute('appBundle_corporation', array('id' => $corporation->getId()));
  }

  return $this->render('AppBundle::corporation.html.twig', array(
    'item' => $corporation,
    'corporation'=>$corporation,
    'assignedUsers'=>$userTable,
    'assignedAgencies' => $agencyTable,
    'form' => $form->createView(),
  ));
}

知道为什么它会冲刷用户而不是代理商吗？

Answer 1

如果您的实体在其他地方（其他控制器等）工作，那么我怀疑您必须 by_reference 在您的 agencies 表单选项中设置为 false。

->add('agencies', EntityType::class, array(
   'class' => 'AppBundle:Agency',
   'query_builder' => function (EntityRepository $er){
   return $er->createQueryBuilder('a')
   ->addOrderBy('a.account', 'ASC');
   },
   'label' => 'label.agencies',
   'choice_label' => function($agency) {
     return $agency->getId() . ' - ' . $agency->getAccount() . ' - ' . $agency->getCityName() . ', ' . $agency->getState();
   },
   'expanded' => false, 'multiple' => true,
   'required' => false,
   'by_reference' => false,
   'translation_domain' => 'Agency',
  ));

您的 user 表单选项中似乎是这样设置的。

我用这种方法解决了我的问题，但@ASOlivieri 的回答可能对 es 很有帮助。我最初做的是：

在实体机构

  /**
 * @ORM\ManyToMany(targetEntity="AppBundle\Entity\Corporation", inversedBy="agencies", cascade={"persist"})
 * @ORM\JoinTable(name="app_agency_corporations",
 *   joinColumns={@ORM\JoinColumn(name="agency_id", referencedColumnName="iata8")},
 *   inverseJoinColumns={@ORM\JoinColumn(name="corporation_id", referencedColumnName="ucid")})
 * @var \AppBundle\Entity\Corporation
 **/
private $corporations;

实体公司

/**
* @ORM\ManyToMany(targetEntity="AppBundle\Entity\Agency", mappedBy="corporations")
**/
private $agencies;

切换时 --> 较短的代码指向该机构的属性个公司，而有关 JoinTable 等的较长代码则适用于该机构的属性个代理机构。

如果有人能向我解释为什么这是解决方案，我会很高兴！
