我正在使用Symfony 2.8
我在User和Sectors实体之间有很多关系，插入效果很好，但是创建编辑表单（editAction函数）无效。所有代码都在那里：

* @var int
*/
protected $id;
/**

我得到错误提示：
类型错误：传递给UserBundle \ Form \ Type \ ProfileAboutMeFormType :: UserBundle \ Form \ Type {closure}（）的参数2必须是Doctrine \ Common \ Collections \ ArrayCollection的实例，Doctrine \ ORM \ PersistentCollection的实例已给定，在第383行的/src/UserBundle/Form/Type/ProfileAboutMeFormType.php中调用
我应该将getSectors方法更改为PersistentCollection吗？还是我需要彻底改变我的方法？
答案 0 :(得分：1)
是的，基本上回答了我自己的问题。对于这种方法，我有自己的解决方案。我必须将“事件监听器”更改为“编辑表单”。
据我了解，当您按存储库查询数据库时，会得到 PersistentCollection，当您与实体合作时，您会得到 ArrayCollection
我在$ formModify函数中将\ Doctrine \ Common \ Collections \ ArrayCollection $ sector更改为数组$ sector。我也更改了PRE_SET_DATA和POST_SUBMIT事件。
下面是更改的事件侦听器的完整代码。
$factory = $builder->getFormFactory();
$formModify = function (FormInterface $form, array $sector, $factory) {
$output = [];
foreach($sector as $sec) {
$output[] = $sec;
}
$formOption = array(
'class' => 'Cocorico\UserBundle\Entity\UserAccreditation',
'multiple' => true,
'auto_initialize' => false,
'required' => false,
'expanded' => true,
'label' => 'Accreditations',
'choice_attr' => function ($output) {
return ['class' => 'attr_checkbox'];
},
'query_builder' => function(EntityRepository $ertt) use ($output) {
// build a custom query, or call a method on your repository (even better!)
$qb = $ertt->createQueryBuilder('g');
$qb->select(array('g'));
$qb->where('g.sector IN (:sector_id)');
$qb->setParameters( array('sector_id' => $output) );
$qb->orderBy('g.name', 'ASC');
return $qb;
},
);
$form->add($factory->createNamed('accreditationdata', EntityType::class, null, $formOption));
};
$builder->addEventListener(FormEvents::PRE_SET_DATA,function (FormEvent $event) use ($formModify,$factory) {
$data = $event->getData();
$form = $event->getForm();
if ($data != null)
$newarray = [];
foreach ($data->getSectors() as $post) {
// $post is not an array
$newarray[] = $post->id;
}
$formModify($event->getForm(), $newarray,$factory);
}
);
$factory = $builder->getFormFactory();
$builder->get('sectors')->addEventListener(FormEvents::POST_SUBMIT,function (FormEvent $event) use ($formModify,$factory) {
$sector = $event->getForm()->getData();
$created_array = array($sector->getId());
$array = [];
foreach($created_array as $secval) {
$array[] = $secval;
}
$formModify($event->getForm()->getParent(), $array,$factory);
}
);
这对我有用。希望它对这种方法有帮助。
