私がやろうとしているのは、別のエンティティ（ファイルエンティティ）から注目の写真を選択できる投稿（投稿エンティティ）フォームを取得することです。
最後に、「featured Image」タイプのファイルのみを表示したいのですが、query_builderを削除しても、次のような例外が発生します。
クラス「Site\Backend \ Adminbundle \ Entity \ File」は、管理されたDoctrineエンティティではないようです。マップするのを忘れましたか？
これが私のPostTypeフォームです
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');
}
))
}
一方、私には2つのエンティティがあります。
