Question

我有一个单页应用程序，我使用symfony作为Rest API。

在我的对象“ResidenceIntervenant中，我有一个ManyToOne关系：

manyToOne:
    intervenant:
        targetEntity: Intervenant
        cascade: {  }
        fetch: LAZY
        mappedBy: null
        inversedBy: null
        joinColumns:
            intervenant_id:
                referencedColumnName: id
        orphanRemoval: false

当我这样做时：

$myData = json_decode($request->getContent(), true);
$intervenant = $this->em->getRepository('AppBundle:Intervenant')->find($intervenantId);
$relation = new ResidenceIntervenant();
$myData['intervenant'] = $intervenant->getId();
$form_relation = $this->formFactory->create(ResidenceIntervenantType::class, $relation, ['method' => "POST"]);
$form_relation->submit($myData, TRUE);
if ( ! $form_relation->isValid()) {
    $this->em->persist($relation);
    $this->em->flush();
}

它有效，我的表格中有id

当我这样做时：

$myData = json_decode($request->getContent(), true);
$intervenant = $this->em->getRepository('AppBundle:Intervenant')->find($intervenantId);
$relation = new ResidenceIntervenant();
$relation->setIntervenant($intervenant);
$form_relation = $this->formFactory->create(ResidenceIntervenantType::class, $relation, ['method' => "POST"]);
$form_relation->submit($myData, TRUE);
if ( ! $form_relation->isValid()) {
    $this->em->persist($relation);
    $this->em->flush();
}

它不会持久存在

这是正常的吗？

我的FormType biuldForm方法：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('contratNum')
        ->add('appareilNum')
        ->add('intervenantOrigine')
        ->add('intervenant')
        ->add('residence');
}

感谢您的帮助

编辑：添加信息以显示我的实体

我尝试添加这些linee但它既不起作用：

$intervenant->addResidenceIntervenant($relation);
$this->em->persist($intervenant);
$this->em->flush();

编辑：问题已解决 我像这样更新了addResidenceIntervenant：

public function addResidenceIntervenant(\AppBundle\Entity\ResidenceIntervenant $residenceIntervenant)
{
    $this->residenceIntervenant[] = $residenceIntervenant;
    $residenceIntervenant->setIntervenant($this);

    return $this;
}

在坚持我的关系之后我添加了这些行：

$intervenant->addResidenceIntervenant($relation);
$this->em->persist($intervenant);

Answer 1

你的第二个例子有这一行：

$relation->setIntervenant($intervenant);

方法setIntervenant()是否设置了关系？

我认为你应该这样做：

public function setIntervenant(Intervenant $intervenant)
{
    $this->intervenant = $intervenant;
    $intervenant->setResidence($this);
}

无论如何，Doctrine中的关系可以是单向的或双向的。

您的Many-To-One关系似乎是单向的。您应该在One-To-Many实体上设置Intervenant关系。

在Doctrine文档中了解更多相关信息：

Many-to-One, Unidirectional（这就是你所做的）
One-to-Many, bidirectional（这是你应该做的）
One-To-Many, Unidirectional with Join Table（仅为完整性）

因此，当您的Intervenant必须被视为Doctrine文档中的Feature时，您应该将ResidenceIntervenant描述为Product。{/ 1} >
