Question

有两个实体（人n：1手机），我想在personEntity中嵌入phoneEntity。我做了基于symfony2嵌入式表单教程的任何事情，但我发现了这个错误：

通过这种关系找到了一个新的实体＆＃39; S1 \ EphoneBundle \实体\ PersonEntity＃phoneEntity＆＃39;那不是配置为级联实体的持久化操作： S1 \ EphoneBundle \实体\ PhoneEntity @ 0000000033dcabf90000000076607b90。解决此问题：显式调用EntityManager＃persist（）on 这个未知的实体或配置级联持久存在此关联映射例如@ManyToOne（..，cascade = {＆＃34; persist＆＃34;}）。如果你无法找出导致问题实施的实体＆＃39; S1 \ EphoneBundle \实体\ PhoneEntity #__的toString（）＆＃39;得到一个线索。

以下是我在personEntityController中的新动作：

public function newAction()
{
    $entity = new PersonEntity();


    $ph1 = new PhoneEntity();
    $entity->getPhoneEntity()->add($ph1);

    $em = $this->getDoctrine()->getManager();
    $em->persist($entity);
    $em->persist($ph1);

    $form   = $this->createCreateForm($entity);

    return $this->render('S1EphoneBundle:PersonEntity:new.html.twig', array(
        'entity' => $entity,
        'form'   => $form->createView(),
    ));
}

我的人类型：

Answer 1

当您persist() PersonEntity然后PhoneEntity个实体时，Doctrine2正在寻找id PersonEntity，以便将此人与电话相关联。缺少此id会导致错误。

您必须在2 flush()次操作之间致电persist()：

# this is needed at the start of the file
use Symfony\Component\HttpFoundation\Request;

public function newAction(Request $request)
{
    $entity = new PersonEntity();

    $ph1 = new PhoneEntity();
    $entity->addPhoneEntity($ph1);

    $form = $this->createForm(new PersonEntityType(), $entity);

    $form->handleRequest($request);

    if ($form->isValid())
    {
        $em = $this->getDoctrine()->getManager();
        $em->persist($ph1);
        $em->flush();
        $em->persist($entity);
        $em->flush();
    }

    return $this->render('S1EphoneBundle:PersonEntity:new.html.twig', array(
        'entity' => $entity,
        'form'   => $form->createView(),
    ));
}

Answer 2

试试这个

 /**
 * Add phoneEntity
 *
 * @param \S1\EphoneBundle\Entity\PhoneEntity $phoneEntity
 * @return PersonEntity
 */
public function addPhoneEntity(\S1\EphoneBundle\Entity\PhoneEntity $phoneEntity)
{
    $this->phoneEntity[] = $phoneEntity;
     $phoneEntity->setPersonEntity($this);
    return $this;
}


 /**
 * set PhoneEntity
 *
 * @param \Doctrine\Common\Collections\ArrayCollection $phones
 */
public function setPhoneEntity(\Doctrine\Common\Collections\ArrayCollection $phones) {
    foreach ($phones as $phone) {
        $phone->setPersonEntity($this);
    }
    $this->phoneEntity = $phones;
}

嵌入式表单有什么问题？
