Symfony2 - 无法显示实体的值

Question

我findOneBy在我的实体中找到(使用)一个单行.这是代码:

$userown = $this->getDoctrine()->getRepository('GameShelfUsersBundle:Own')
    ->findOneBy(array(
        'game' => $game->getId(),
        'user' => $em->getRepository('GameShelfUsersBundle:User')->find($session->getId())
    ));

现在我将它传递给模板userown.但是当我尝试在树枝上打印时,使用{{ userown.typo }}它会引发错误:

An exception has been thrown during the rendering of a template ("Catchable Fatal Error: Object of class Proxies\__CG__\GameShelf\UsersBundle\Entity\OwnState could not be converted to string in D:\!!XAMPP\htdocs\

我的实体就在这里.

Answer 1

Doctrine会自动解析您的外键,因此$typo不是字符串而是对象.正如错误消息告诉您的那样,此对象无法转换为字符串,因此打印失败.

您可以__toString()在OwnStateEntity中实现该方法(它应该返回一个字符串),也可以打印OwnState对象的实际属性:{{ userown.type.someProperty }}.
