创建操作。 为具有1对1关系的两个实体生成表单
问题描述：
What I want to achieve:
User entity have UserInfo property where is stored all info about User. I wan't to create UserInfo entity when User entity is created and link these two.
UserType:
...
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('username')
->add('password', 'password') //drugi argument robi input jako password
;
$builder->add('info', new UserInfoType());
}
...
User:
...
/**
* @var UserInfo
*
* @ORM\OneToOne(targetEntity="UserInfo", mappedBy="owner", cascade={"persist", "remove"})
* */
private $info;
...
UserInfo:
/**
* @var User
*
* @ORM\OneToOne(targetEntity="User", inversedBy="info", cascade={"persist"})
* @ORM\JoinColumn(name="owner_id", referencedColumnName="id")
**/
private $owner;
...
/**
* Set owner
*
* @param \Custom\AzureusBundle\Entity\User $owner
* @return UserInfo
*/
public function setOwner(\Custom\AzureusBundle\Entity\User $owner)
{
$owner->setInfo($this);
$this->owner = $owner;
return $this;
}
Why after creating User and UserType at the same time (same form) userInfo hasn't owner_id value in database? These entities are not linking each other after creating.
I assume that I should call setOwner() function somewhere. But I don't know where.
答
As @Cerad said in comment above I should create UserInfo in User controller (Create function).
public function createAction(Request $request)
{
$entity = new User();
$user_info = new UserInfo();
$entity->setInfo($user_info);
$user_info->setOwner($entity);
...
if ($form->isValid()) {
...
$em->persist($entity);
$em->persist($user_info);
...
