我是Doctrine ODM的新手，我完全坚持一个简单的查询:(
让我先从文档结构开始：
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 ...
)
此文档名为投票。
我的问题是，如何找到特定选民的投票文档（存储在 voteList.latest.voter ）
我试过这样：
$builder
->field('voteList.latest.voter')->references($voter)
->getQuery()
->execute();
这样也是：
$result = $builder
->field('voteList.latest.voter.$id')->equals(new \MongoId($voter->getId()))
->getQuery()
->execute();
两者都导致了这个例外：
Doctrine\ODM\MongoDB\MongoDBException: No mapping found for field 'voteList.latest.voter' in class 'App\BaseBundle\Document\Voting'.
我是否错误地构建了查询，或者我的文档类可能出错？
感谢阅读，任何建议都表示赞赏。
