Symfony的左连接查询

Question

我有它正确地运行下面的查询：

$q = $this->createQuery('e') 
    ->where('e.Persons_idUser =?', $request) 
    ->leftJoin('e.JobTitles jt') 
    ->leftJoin('e.EmploymentLevels el'); 

，但是当我遍历结果，并尝试从左边的领域加入：

foreach ($work as $w){ 
    echo $w->employername; 
    echo $w->jobtitle; // this is from the left join 
    echo $w->employmentlevel; // this is from the left join 
} 

，我得到了以下错误消息： 未知记录属性/相关组件“JOBTITLE”的“经验”

任何人都得到了线索？我如何回应左连接的字段？

Answer 1

解决方案：

foreach ($work as $w){ 
echo $w->employername; 
echo $w->JobTitles->jobtitle; // this is from the left join 
echo $w->EmploymentLevels->employmentlevel; // this is from the left join 
} 

Answer 2

<?php 
    foreach ($work as $w){ 
     echo $w->employername; 
     foreach($w->JobTitles as $job){ 
      echo $job->jobtitle; // this is from the left join 
     } 
     foreach($w->EmploymentLevels as $employ){ 
      echo $employ->employmentlevel; // this is from the left join 
     } 
    } 

?> 

这将作为对象的symfony的回报阵列和加入的元素表子阵列下前来
