Doctrine ODM/MongoDB：如何查詢嵌入文檔中的引用？

Question

我是新來的學說ODM，我完全陷入了簡單的查詢:(

讓我先從文檔結構：

Array 
(
[_id] => 4ee1e4527f749c9411000012 
[voteList] => Array 
    (
     [_id] => 4ee1e4527f749c9411000013 
     [votes] => Array 
      (
       ... stripped ... 
      ) 
     [latest] => Array 
      (
       [_id] => 4ee1e4527f749c9411000014 
       [rating] => 1 
       [voter] => Array 
        (
         [$ref] => Voter 
         [$id] => 4ee1e4527f749c941100000f 
         [$db] => x_test 
        ) 

      ) 
    ) 
    ... stripped ... 
) 

這份文件被稱爲投票

我的問題是，如何由特定選民（存儲在voteList.latest找到投票 -documents .voter）。

我想它是這樣的：

$builder 
    ->field('voteList.latest.voter')->references($voter) 
    ->getQuery() 
    ->execute(); 

而且這種方式也：

$result = $builder 
    ->field('voteList.latest.voter.$id')->equals(new \MongoId($voter->getId())) 
    ->getQuery() 
    ->execute(); 

兩者都導致此異常：

Doctrine\ODM\MongoDB\MongoDBException: No mapping found for field 'voteList.latest.voter' in class 'App\BaseBundle\Document\Voting'. 

難道我不當構建查詢或者我的文檔類可能有問題？

想通了它不工作因學說，ODM錯誤。
