我试图坚持收集表格......奇怪的是代码在 2.0 上工作但在 2.2 上没有(我错了,但我很确定它是)
这是代码的相关部分..
错误
Error: Call to a member function setEventId() on a non-object in C:\wamp\www\new\src\Splurgin\EventsBundle\Entity\SplurginEventEvents.php line 317
在我的表格类型中
->add('packages' , 'collection', array('type'=>new SplurginEventPackagesType(),
'allow_add' => true,
'by_reference' => false,
))
错误所在的我的事件实体
/**
* @ORM\OneToMany(targetEntity="Splurgin\EventsBundle\Entity\SplurginEventPackages", mappedBy="eventId" ,cascade={"persist"})
*/
private $packages;
public function __construct()
{
$this->media = new \Doctrine\Common\Collections\ArrayCollection();
$this->packages = new \Doctrine\Common\Collections\ArrayCollection();
}
public function getPackages()
{
return $this->packages;
}
public function setPackages($packages)
{
$this->packages = $packages ?: new \Doctrine\Common\Collections\ArrayCollection();
foreach ($this->packages as $package) {
$package->setEventId($this); // line of error
}
return $this->packages;
}
我的包裹实体
/**
* @var integer $eventId
* @ORM\ManyToOne(targetEntity="SplurginEventEvents", inversedBy="packages")
* @ORM\JoinColumn(name="event_id", referencedColumnName="id")
*/
private $eventId;
/**
* Set eventId
*
* @param integer $eventId
*/
public function setEventId(\Splurgin\EventsBundle\Entity\SplurginEventEvents $eventId)
{
$this->eventId = $eventId;
}
/**
* Get eventId
*
* @return integer
*/
public function getEventId()
{
return $this->eventId;
}
包装类型
class SplurginEventPackagesType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('price')
->add('description')
->add('items')
;
}
public function setDefaultOptions(OptionsResolverInterface $options)
{
return array(
'data_class' => 'Splurgin\EventsBundle\Entity\SplurginEventPackages',
);
}
public function getName()
{
return 'packages';
}
}
在我的控制器中,仅检查表单是否有效并保持它没有什么有趣的。
更新:我已经更新了 js 文件
The placeholder was changed from $$name$$ to __name__ in Symfony 2.1
update2 : 似乎我需要添加、添加和删除功能.. 但我不确定
更新 3:添加了 add 和 remove 方法(就像在文档中一样),但我仍然得到相同的错误,但是在 add 方法中
这是 add 方法的代码,唯一改变的代码是 setPackages 方法
public function getPackages()
{
return $this->packages;
}
public function addPackage( ArrayCollection $package) // if i put the type hinting i get an error that array collection was not passed , i get a normal array instead
{
$package->setEventId($this); // this thoughs an error (because we cant use set event method on an array
$this->packages->add($package);
}
public function removePackage(ArrayCollection $package)
{
//...
}
public function setPackages($packages)
{
$this->packages = $packages ;
return $this->packages;
}
