symfony2實體字段類型錯誤

Question

我還沒有找到關於如何做到這一點的任何可靠的例子。

我有我的實體盾牌，它可以有一個以上的盾牌類型。我想要做的是創建一個表單，用不同的Shieldtypes創建一個新的Shield。

這是我的代碼，我真的不知道哪裏是我的錯誤：

錯誤是：

Entities passed to the choice field must be managed 
500 Internal Server Error - FormException

    } 
    public function getTitle() 
    { 
     return $this->title; 
    } 
} 

它可以是一個有點混亂，但：

Shield entity (database) 
ShieldTypes entity (database) 
ShieldType form (abstracttype) 

謝謝...

Answer 1

所以，問題是，我沒有」創建一個存儲庫。我創建了它（最後見代碼），我仍然得到'傳遞給選擇字段的實體必須被管理'錯誤。

然後我設置多發爲true：

$builder->add('types','entity', 
       array(
        'class'=>'Armory\SearchBundle\Entity\ShieldTypes', 
        'query_builder'=> function(\Armory\SearchBundle\Entity\Repository\ShieldTypesRepository $repository){ 
            return $repository->createQueryBuilder('s')->orderBy('s.id', 'ASC');}, 
        'property'=>'title', 
        'multiple'=>true 
        ) 
       ); 

我希望有人認爲這是有用的，因爲如果我有過這一點，它會如此簡單。

代碼爲我的倉庫：

namespace Armory\SearchBundle\Entity\Repository; 
use Doctrine\ORM\EntityRepository; 

class ShieldTypesRepository extends EntityRepository 
{ 
    public function getAll() 
    { 
     return $this->_em->createQuery('SELECT s FROM Armory\SearchBundle\Entity\ShieldTypes s') 
         ->getResult(); 
    } 
}
