Symfony 2.8文件上传“无法读取索引"....因为Entity不实现ArrayAcces，所以从类型的对象中删除. [英] Symfony 2.8 file uploading "Cannot read index "..." from object of type because Entity doesn't implement ArrayAcces."
问题描述
我的editAction遇到问题，当我尝试编辑一些我感到骄傲的东西
I've got a problem with my editAction, when I'm trying to edit some proudct i'm getting
无法从类型为的对象读取索引标记" "ShoeShopBundle \ Entity \ Buty"，因为它没有实现 \ ArrayAccess.
Cannot read index "marka" from object of type "ShoeShopBundle\Entity\Buty" because it doesn't implement \ArrayAccess.
我早些时候得到
窗体的视图数据应该是class的一个实例 Symfony \ Component \ HttpFoundation \ File \ File，但是是一个(n)字符串.你 可以通过将"data_class"选项设置为null或通过避免此错误 添加一个将一个(n)字符串转换为实例的视图转换器 \ Symfony \ Component \ HttpFoundation \ File \ File.
The form's view data is expected to be an instance of class Symfony\Component\HttpFoundation\File\File, but is a(n) string. You can avoid this error by setting the "data_class" option to null or by adding a view transformer that transforms a(n) string to an instance of Symfony\Component\HttpFoundation\File\File.
错误，因此我将 configureOptions 中的data_class更改为null，并将'data_class' => 'path_to_entity'添加到每个字段.这是我的表格:
error, so I changed data_class in configureOptions to null and added 'data_class' => 'path_to_entity' to every field. This is my form:
class ButyType extends AbstractType
{
/**
* @param FormBuilderInterface $builder
* @param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('marka', ChoiceType::class, array(
'data_class' => 'ShoeShopBundle\Entity\Buty',
'choices' => ['Adidas', 'Asics', 'Nike', 'Puma'
]
))
->add('model', TextareaType::class, array(
'data_class' => 'ShoeShopBundle\Entity\Buty',
))
->add('kolor', TextareaType::class, array(
'data_class' => 'ShoeShopBundle\Entity\Buty',
))
->add('cena', TextareaType::class, array(
'data_class' => 'ShoeShopBundle\Entity\Buty',
))
->add('rozmiar', EntityType::class, array(
'class' => 'ShoeShopBundle:Rozmiar',
'expanded' => true,
'multiple' => true,
'query_builder' => function (EntityRepository $er) {
return $er->createQueryBuilder('r')
->orderBy('r.rozmiar', 'ASC');
}, 'choice_label' => 'rozmiar',
)
)
->add('zdjecie', FileType::class, array(
'data_class' => 'Symfony\Component\Form\Extension\Core\Type\FileType',
'property_path' => 'zdjecie',
'label' => 'Zdjecie (img file)'))
->add('zdjecieMIN', FileType::class, array(
'data_class'=> 'Symfony\Component\Form\Extension\Core\Type\FileType',
'property_path' => 'zdjecieMIN',
'label' => 'Zdjecie miniatura (img file)'));
}
/**

public function configureOptions(OptionsResolver $resolver)

$resolver->setDefaults(array(

任何人都可以告诉我怎么了吗?预先感谢.
Can anyone please tell me what's wrong? Thanks in advance.
推荐答案
您必须将表单的'data_class'选项设置为适当的类，否则Symfony属性访问器将假定它是一个数组.
You have to set the 'data_class' option of your form the the appropriate class otherwise the Symfony property accessor assumes it's an array.
/**
* @param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => Buty::class
));
}
