我有三个实体Post Caroussel和CarousselImg。 其中Carousel实体与邮政实体有关post_id 和CarousselImg实体与卡洛斯实体有关，caroussel_id。 多对一和一对多的关系是由教义产生的。收集形式Symfony收集表格
问题是当我尝试添加包含caroussel [包含carousselimg]的帖子。
在类“的appbundle \实体\ Caroussel”的属性“carousselImgs”可以与方法“addCarousselImg（）”，“removeCarousselImg（）”，但新的值必须是一个数组或的实例来限定\ Traversable，“AppBundle \ Entity \ CarousselImg”给出。
这里是柱式我caroussel部分
->add('caroussels',CollectionType::class, array(
'entry_type' => CarousselType::class,
'allow_add' => true,
'delete_empty'=>true,
'by_reference' => false,
'prototype' => true,
'entry_options' => array(
'attr' => array('class' => 'caroussels-box')
),
)
)
这里是Caroussel型我carousselImg部分
$builder->add('title')->add('carousselImgs', new CarousselImgType());
感谢您的帮助

您好感谢您的答案，但我因此未工作，同样的错误 –
我们可以有类_CarousselType_和_AppBundle \实体\ Caroussel_请的全部代码？ –
ueah我会更新帖子 –
