我想在两个实体之间建立关系,但由于某种原因,我在其中一个值上得到NULL ...
所以在我的皮肤实体中,我有一个带有关系的email_registration_id字段:
/**
* @ORM\ManyToOne(targetEntity="Project\UserBundle\Entity\Email")
* @ORM\JoinColumn(name="email_registration_id", referencedColumnName="id")
*/
protected $email_registration_id;
/**
* Set email_registration_id
*
* @param \Project\UserBundle\Entity\Email $email_registration_id
* @return Skin
*/
public function setEmailRegistrationId(\Project\UserBundle\Entity\Email $email_registration_id = null)
{
$this->email_registration_id = $email_registration_id;
return $this;
}
/**
* Get email_registration_id
*
* @return \Project\UserBundle\Entity\Email
*/
public function getEmailRegistrationId()
{
return $this->email_registration_id;
}
这是电子邮件实体:
/**
* Project\UserBundle\Entity\Email
*
* @ORM\Entity
* @ORM\Table(name="email")
*/
class Email {
/**
* @var integer $id
*
* @ORM\Column(name="id", type="integer")
* @ORM\Id
* @ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* @var string $title
*
* @ORM\Column(name="title", type="string")
*/
protected $title;
/**
* @var string $registration_content
*
* @ORM\Column(name="registration_content", type="string")
*/
protected $registration_content;
/**
* @var string $confirmation_apuestas
*
* @ORM\Column(name="confirmation_apuestas", type="string")
*/
protected $confirmation_apuestas;
/**
* Get id
*
* @return integer
*/
public function getId()
{
return $this->id;
}
public function setId() {
$this->id = null;
}
/**
* Set title
*
* @param string $title
* @return Email
*/
public function setTitle($title)
{
$this->title = $title;
return $this;
}
/**
* Get title
*
* @return string
*/
public function getTitle()
{
return $this->title;
}
/**
* Set registration_content
*
* @param string $registration_content
* @return Email
*/
public function setRegistrationContent($registration_content)
{
$this->registration_content = $registration_content;
return $this;
}
/**
* Get registration_content
*
* @return string
*/
public function getRegistrationContent()
{
return $this->registration_content;
}
/**
* Set $confirmation_apuestas
*
* @param string $confirmation_apuestas
* @return Email
*/
public function setConfirmationApuestas($confirmation_apuestas)
{
$this->confirmation_apuestas = $confirmation_apuestas;
return $this;
}
/**
* Get $confirmation_apuestas
*
*
@return string
*/
public function getConfirmationApuestas()
{
return $this->confirmation_apuestas;
}
}
现在在我的cms中我创建了一个这样的新电子邮件:
/**
* @Route("/new", name="cms_email_new")
* @Method({"GET"})
* @Template()
*/
public function newAction() {
$item = new Email();
$form = $this->createForm(new EmailType($this->container->getParameter("langs")), $item);
return array('form' => $form->createView(), 'item' => $item);
}
表格:
public function buildForm(FormBuilderInterface $builder, array $option) {
$builder->add('title', 'text', array('label' => 'cms.Title'));
$builder->add('registration_content', 'textarea', array('label' => 'cms.registration.content'));
$builder->add('confirmation_apuestas', 'textarea', array('label' => 'cms.confirmation.apuestas'));
}
public function getDefaultOptions(array $options) {
return array(
'data_class' => 'Project\UserBundle\Entity\Email',
);
}
这是我将电子邮件持久保存到数据库的方式:
/**
* @Route("/save", name="cms_email_save")
* @Template("ProjectUserBundle:EmailAdmin:new.html.twig")
* @Method({"POST"})
*/
public function saveAction(Request $request) {
$item = new Email();
$type = new EmailType($this->container->getParameter("langs"));
$form = $this->createForm($type, $item);
$form->bind($request);
$em = $this->getEntityManager();
if ($form->isValid()) {
$this->upload($form, $item);
$em->persist($item);
$em->flush();
return $this->redirect($this->generateUrl('cms_skin_email_list', array('skin_id' => $item->getId())));
}
return array('form' => $form->createView(), 'item' => $item);
}
问题是它创建了一个电子邮件,但在我的皮肤实体中,email_registration_id只是NULL而不是电子邮件ID ...也许我错过了什么?
更新
所以这就是我根据我得到的回答制作的:
类电子邮件{
/**
* @ORM\OneToMany(targetEntity="Project\SkinBundle\Entity\Skin", mappedBy="email_registration_id")
*/
protected $skin;
/**
* Set skin
*
* @param string $skin
* @return Email
*/
public function setSkin(\Project\SkinBundle\Entity\Skin $skin = null)
{
$this->skin = $skin;
return $this;
}
/**
* Get skin
*
* @return string
*/
public function getSkin()
{
return $this->skin;
}
形式:
public function buildForm(FormBuilderInterface $builder, array $option) {
$builder->add('title', 'text', array('label' => 'cms.Title'));
$builder->add('registration_content', 'textarea', array('label' => 'cms.registration.content'));
$builder->add('confirmation_apuestas', 'textarea', array('label' => 'cms.confirmation.apuestas'));
$builder->add('skin', 'entity', array(
'class' => 'ProjectSkinBundle:Skin',
'property' => 'id',
));
}
但是,当我尝试刷新数据库时,我收到此错误:
ContextErrorException: Catchable Fatal Error: Argument 1 passed to Doctrine\Common\Collections\ArrayCollection::__construct() must be of the type array, object given, called in C:\wamp\www\Company\front\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php on line 528 and defined in C:\wamp\www\Company\front\vendor\doctrine\collections\lib\Doctrine\Common\Collections\ArrayCollection.php line 48
答案 0 :(得分:0)
新电子邮件的创建与皮肤对象无关,这是正常的。怎么可能呢?该关系是单向的,只有在您创建皮肤并且给它发送电子邮件时才有效。要创建电子邮件并为其提供外观,您必须使关系成为双向关系,并将其添加到您的电子邮件表单中。
为此,我要执行以下操作:
/*
* Class Project\UserBundle\Entity\Email
*/
class Email {
...
/**
* @ORM\OneToMany(targetEntity="Project\SkinBundle\Entity\Skin", mappedBy="email_registration_id")
*/
protected $skin;
并以您的形式:
public function buildForm(FormBuilderInterface $builder, array $option) {
$builder->add('title', 'text', array('label' => 'cms.Title'))
->add('registration_content', 'textarea', array('label' => 'cms.registration.content'))
->add('confirmation_apuestas', 'textarea', array('label' => 'cms.confirmation.apuestas'))
->add('skin')
;
}
和PS:你不应该使用bind()方法来处理请求,不推荐使用它。而是使用:
$form->handleRequest($request);
更新1:不要忘记更新你的ManyToOne注释添加inversedBy部分:
@ORM\ManyToOne(targetEntity="Project\UserBundle\Entity\Email", inversedBy="skin")
当然,还要更新您的数据库。
