我有一个包含2个数组的文档，我试图使用$elemMatch同时基于某种条件更新两个数组的特定数组元素。
查询
targetManagementSchema.findOneAndUpdate({
franchiseeId : franchiseeId,
'yearlyTarget.year': 2019,
'quarterlyTarget': {
$elemMatch: {
'quarter.from': 7,
'quarter.to': 9
}
},
'monthlyTarget': {
$elemMatch: {
'month': 7
}
}
}, {
$set: {
'yearlyTarget.targetAchieved': 101540.7,
'quarterlyTarget.$.targetAchieved': 101540.7,
'monthlyTarget.$.targetAchieved': 101540.7
}
}, (err, updatedTargetRes) => {
if (err) {
console.log("error in updating targetsAchieved " + err);
} else if (updatedTargetRes != null && updatedTargetRes != '') {
console.log(updatedTargetRes + " :updatedTargetRes");
} else {
console.log("target not updated");
}
})

它采用第一个匹配项的索引，即1数组的quarterlyTarget并将其应用于monthlyTarget数组，而不是根据我指定的条件获取索引。因此，更新了monthlyTarget数组的错误索引。
我知道可以使用arrayFilters来实现，我也做到了。但是我正在使用的mongodb版本是3.2，不幸的是我无法升级它，因此，我需要使用3.2支持的方法。

好吧，您错过了{upsert:true}
我在Mongo Editor上运行了该查询，并且该查询有效。让我知道这是否适合您（也知道我只使用了部分查找查询，因为只有一个文档。您可以继续使用完整的查找块。我的重点是更新文档）
db.user_test.findOneAndUpdate(
{franchiseeId: "5c42bd6085edaa215cba5a21", "yearlyTarget.year":2019, "quarterlyTarget": {
$elemMatch: {
"quarter.from": 7,
"quarter.to": 9
}
}},
{
$set: {
'yearlyTarget.targetAchieved': 101540.7,
'quarterlyTarget.$.targetAchieved': 101540.7,
'monthlyTarget.$.targetAchieved': 101540.7
}
},
{upsert:true})
这是我更新后返回的文档
