FormType 中的实体选择列表不发送值

Entity choice list in FormType isn't sending values

我的 FormType 中有以下代码:

/**
 * @var User
 */
protected $currentUser;

/**
 * param User $currentUser
 */
public function __construct($currentUser)
{
    $this->currentUser = $currentUser;
}

public function buildForm(FormBuilderInterface $builder, array $options)
{   
    $currentUser = $this->currentUser;

    $builder
        ->add('breedingPairMale', 'entity', array(
            'class' => 'Breedr\GeckoBundle\Entity\Gecko',
            'property' => 'id',
            'property' => 'name',
            'placeholder' => 'Choose a Male',
            'query_builder' => function(EntityRepository $er) use ($currentUser) {
                return $er->createQueryBuilder('g')
                    ->where('g.user = :currentUser')
                    ->andWhere('g.sex = :sex')
                    ->orderBy('g.name')
                    ->setParameter('currentUser', $currentUser)
                    ->setParameter('sex', 'Male');
            }
        ))
        ->add('breedingPairFemale', 'entity', array(
            'class' => 'Breedr\GeckoBundle\Entity\Gecko',
            'property' => 'id',
            'property' => 'name',
            'placeholder' => 'Choose a Female',
            'query_builder' => function(EntityRepository $er) use ($currentUser) {
                return $er->createQueryBuilder('g')
                    ->where('g.user = :currentUser')
                    ->andWhere('g.sex = :sex')
                    ->orderBy('g.name')
                    ->setParameter('currentUser', $currentUser)
                    ->setParameter('sex', 'Female');
            }
        ))
        ->add('breedingPairDate')
        ->add('breedingPairSeason')
    ;
}

构建 select 框绝对没问题,当我检查元素时,我看到值是壁虎的 ID,名称也可见,所以一切都很好。

它也正确提交了表单:

public function createAction(Request $request)
{
    $entity = new Pairs();
    $form = $this->createCreateForm($entity);
    $form->handleRequest($request);

    if ($form->isValid()) {
        $em = $this->getDoctrine()->getManager();
        $em->persist($entity);
        $em->flush();

        return $this->redirect($this->generateUrl('pairs_show', array('id' => $entity->getId())));
    }

    return $this->render('BreedrBreedingPairsBundle:Pairs:new.html.twig', array(
        'entity' => $entity,
        'form'   => $form->createView(),
    ));
}

/**
 * Creates a form to create a Pairs entity.
 *
 * @param Pairs $entity The entity
 *
 * @return \Symfony\Component\Form\Form The form
 */
private function createCreateForm(Pairs $entity)
{
    $currentUser = $this->getUser()->getId();

    $form = $this->createForm(new PairsType($currentUser), $entity, array(
        'action' => $this->generateUrl('pairs_create'),
        'method' => 'POST',
    ));

    $form->add('submit', 'submit', array('label' => 'Create'));

    return $form;
}

... 但是,当它保存到数据库中时,数据库中的值 table 对于男性和女性是 0

这是我的 id 来自 Gecko class:

/**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

我需要建立 ManyToOne 关系才能正常工作吗?还是我还漏掉了什么?

提前致谢,

好的,我认为这里发生的是数据类型不匹配。

  • 您的表单显示数据类型为 entity(属于 Gecko
  • 你的实体,有 @Column 注释,告诉它是简单类型

处理 Request 后,一切似乎都找到了 - Gecko 实体已分配给 $breedingPairMale$breedingPairFemale。然而,当谈到坚持时,我很惊讶它没有中断。我很好奇为什么。

要解决此问题,您需要在 Pairs 实体中修复(或实际上创建)关系:

class Pairs
{
    // ................
    // ................
    // ................

    /**
     * @var Breedr\GeckoBundle\Entity\Gecko
     *
     * @ORM\ManyToOne(targetEntity="Breedr\GeckoBundle\Entity\Gecko")
     * @ORM\JoinColumn(name="breeding_pair_male", referencedColumnName="id")
     */
    private $breedingPairMale;

    /**
     * @var Breedr\GeckoBundle\Entity\Gecko
     *
     * @ORM\ManyToOne(targetEntity="Breedr\GeckoBundle\Entity\Gecko")
     * @ORM\JoinColumn(name="breeding_pair_female", referencedColumnName="id")
     */
    private $breedingPairFemale;

    // ................
    // ................
    // ................

现在,$breedingPairMale$breedingPairFemale 不再是 integer 类型,而是 class Gecko 类型,坚持使用它应该有效。
