我是 Doctrine ODM 的新手，我完全被一个简单的查询所困 :(

让我从文档结构开始:

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 ...
)

此文档称为投票。

我的问题是，如何找到特定选民的投票文件(存储在voteList.latest.voter)。

我试过这样的:

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

还有这种方式:

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

两者都导致了这个异常:

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

是我构建的查询不正确还是我的文档类有问题？

感谢阅读，感谢任何建议。

最佳答案

发现由于 doctrine-odm 错误，它无法正常工作。
