我想做的是获得一个Post（Post Entity）表单，在那里我可以从另一个实体（File Entity）中选择一张特色图片。
最后，我想只显示"featured Image"类型的文件，但即使我删除了query_builder，我也会遇到一个异常：
类"Site''Backend''Adminbundle''Entity''File"似乎不是托管条令实体。你忘了画地图了吗？
这是我的PostType表单
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder
->add('title')
->add('thumb', 'entity', array(
'class' => 'Site'Backend'Adminbundle'Entity'File',
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('f')
//->where('f.state = :state')
//->setParameter('state', $prms['state'])
->orderBy('f.dateUpdated', 'DESC');
}
))
}

提前感谢我希望我很清楚，如果不是这样，请告诉我。
尝试更改：
站点''后端''管理员bundle''实体''文件
至
Site''Backend''AdminBundle''Entity''File
解决此问题的另一种方法：
->add('thumb', null, array(
'query_builder' => function(EntityRepository $er) {
return $er->createQueryBuilder('f')
->select('f')
->leftJoin('f.type', 't')
->where('t.name = :type')
->setParameter('type', 'Featured Images')
->orderBy('f.dateUpdated', 'DESC');
}
))
如果您使用多个连接，您可能忘记映射您的捆绑包。确保app/config/config.yml:中是这种情况
orm:
entity_managers:
default:
mappings:
AppBundle: ~
SiteBackendAdminBundle: ~
或者，如果你想拆分为几个实体经理：
orm:
entity_managers:
default:
mappings:
AppBundle: ~
admin:
mappings:
SiteBackendAdminBundle: ~
文件符号/原则：多实体管理者。
