Php 在Symfony中显示实体？

我的任务是转变管理web应用程序的方式

我使用过OpenSkedge（一个开源web应用程序）

我的任务之一是每个用户都应该有一套技能

我已经添加了一个功能，您可以在其中添加这些技能集，并且我还有另一个视图显示用户的信息

用户控制器：

/**
 * Finds and displays a User entity.
 *
 * @param integer $id ID of user
 *
 * @return \Symfony\Component\HttpFoundation\Response
 */
public function viewAction($id)
{

    $em = $this->getDoctrine()->getManager();

    if (is_null($id)) {
        $id = $this->getUser()->getId();
    }

    $entity = $em->getRepository('OpenSkedgeBundle:User')->find($id);
    VarDumper::dump($entity);  
    if (!$entity instanceof User) {
        throw $this->createNotFoundException('Unable to find User entity.');
    }

    $deleteForm = $this->createDeleteForm($id);
    return $this->render('OpenSkedgeBundle:User:view.html.twig', array(
        'entity'      => $entity,
        'skillset'    => $entity->getSkillset(),
        'delete_form' => $deleteForm->createView(),
    ));
}

我在屏幕截图中的用户类中没有看到属性
skillSet
？而且yor for循环为空。可能您希望执行以下操作：`{set.skillset%}{{set.skillset}}{%endfor%}`skillset是实体中的字符串。不能对字符串执行for。@codeneuss No skillset是skillset类中的字符串属性。我在第一次阅读时也落入了同样的陷阱。@dbrumann提到你忘了回应你的技能；）
