Php 使用FOSUserBundle通过queryBuilder连接获取用户名

我使用FOSUserBundle，我需要获取在我的帖子上写评论的用户名

我使用函数

createQuery

获取帖子评论，并将此连接添加到尝试获取姓名中：

<?php

namespace CommentsBundle\Entity;

use FOS\UserBundle\Entity\User;

/**
 * CommentsRepository
 *
 * This class was generated by the Doctrine ORM. Add your own custom
 * repository methods below.
 */
class CommentsRepository extends \Doctrine\ORM\EntityRepository
{
    public function getPostComments($planId)
    {
        $arrPlanComments = array();

        $query = $this->getEntityManager()->createQuery(

            'SELECT 
             c.id, 
             c.fkUser, 
             c.fkReply, 
             c.comment, 
             c.createdAt, 
             c.likes, 
             c.unlikes 
             FROM CommentsBundle:Comments c 
             INNER JOIN UserBundle:User u 
             WITH (c.fkUser = u.id) 
             WHERE 
             c.fkPlan = :planId 
             ORDER BY c.createdAt DESC'

        )->setParameter('planId', $planId);

        try
        {
            $arrPlanComments = $query->getArrayResult();
        }
        catch(\Doctrine\ORM\NoResultException $ex)
        {
            echo $ex->getMessage();
        }

        return $arrPlanComments;
    }

}

根据文档，您必须为用户实体创建一个，它将扩展FOSUser提供的实体。看来你还没那么做。这可能就是您的错误消息所表明的。
谢谢，兄弟，它很有效！。我忘记了安装步骤。；）
