    ],
    "__v": 4
}

让我告诉您我要在这里做什么。这是我的路线

adminRoutes.post(
  '/examination/:patientID/:examID',
  userController.ensureAuthenticated,
  examController.findOneAndUpdate
)

我将_id名患者的:patientID作为_id（文档）通过，而嵌套检查对象的:examID则作为/** * POST /admin/examination/:patientID/:examID **/ exports.findOneAndUpdate = function (req, res) { const query = { examinations: { $elemMatch: { _id: new ObjectId(req.params.examID) } } } const update = { $set: { examinationDate: req.body.examinationDate, daysOfLife: req.body.daysOfLife, currentPMA: req.body.currentPMA, currentWeight: req.body.currentWeight, visitType: req.body.visitType, ODExam: { plusODExam: req.body.plusODExam, zoneODExam: req.body.zoneODExam, ropODExam: req.body.ropODExam, ropODStage: req.body.ropODStage, categoryOD: req.body.categoryOD, apROPOD: req.body.apROPOD }, OSExam: { plusOSExam: req.body.ropOSExam, zoneOSExam: req.body.zoneOSExam, ropOSExam: req.body.ropOSExam, ropOSStage: req.body.ropOSStage, categoryOS: req.body.categoryOS, apROPOS: req.body.apROPOS }, FindingFollowUp: { ropFindings: req.body.ropFindings, followUpPlan: req.body.followUpPlan, nameOfExaminer: req.body.nameOfExaminer, followUpDate: req.body.followUpDate } } } const options = { arrayFilters: [{ 'examinations._id': new ObjectId(req.params.examID) }] } Patient.updateOne(query, update, options, function (err, result) { if (err) { console.log(err) res.send(err) } else { console.log(result) res.send(result) } }) } 通过，我的目标是通过匹配来更新患者的检查考试编号。 这是我的控制器。

MongoError: The array filter for identifier 'examinations' was not used in the update { $set: { daysOfLife: 45 } }

我从Selecting and updating a nested object by it's ObjectId in Mongoose.js获得了参考。但是我遇到了错误。

const update = {
    $set: {
      'examinations.$[exam].examinationDate': req.body.examinationDate,
      'examinations.$[exam].daysOfLife': req.body.daysOfLife,
      'examinations.$[exam].currentPMA': req.body.currentPMA,
      'examinations.$[exam].currentWeight': req.body.currentWeight,
      'examinations.$[exam].visitType': req.body.visitType,
      'examinations.$[exam].ODExam': {
        plusODExam: req.body.plusODExam,
        zoneODExam: req.body.zoneODExam,
        ropODExam: req.body.ropODExam,
        ropODStage: req.body.ropODStage,
        categoryOD: req.body.categoryOD,
        apROPOD: req.body.apROPOD
      },
      'examinations.$[exam].OSExam': {
        plusOSExam: req.body.ropOSExam,
        zoneOSExam: req.body.zoneOSExam,
        ropOSExam: req.body.ropOSExam,
        ropOSStage: req.body.ropOSStage,
        categoryOS: req.body.categoryOS,
        apROPOS: req.body.apROPOS
      },
      'examinations.$[exam].FindingFollowUp': {
        ropFindings: req.body.ropFindings,
        followUpPlan: req.body.followUpPlan,
        nameOfExaminer: req.body.nameOfExaminer,
        followUpDate: req.body.followUpDate
      }
    }
  }

在我这样做时，在这种情况下更新单项检查的有效方法可能是什么。这是仅更新已更改数据的正确方法吗？谢谢您抽出宝贵时间阅读这篇文章。

更新[已解决]。 我在@ thammada.ts的评论帮助下修复了它。非常感谢他。将我的更新更改为：

'exam.id'

，并在arrayFilters上使用了sudo apt update && sudo apt install -y nvidia-docker2 。

您必须按以下步骤更改update和options 

/*
Keep in mind that this will replace the whole element,
if you have other fields not included in the update, they will be removed.
To update new fields without replacing the element,
you have to specify all the fields like this

{
  $set: {
...
    "examinations.$[exam].examinationDate": req.body.examinationDate,
    "examinations.$[exam].daysOfLife": req.body.daysOfLife,

...
    "examinations.$[exam].ODExam.plusODExam": req.body.plusODExam,
    "examinations.$[exam].ODExam.zoneODExam": req.body.zoneODExam
...
  }
}
*/
const update = {
  $set: {
    "examinations.$[exam]": {
      _id: new ObjectId(req.params.examID),
      examinationDate: req.body.examinationDate,
      daysOfLife: req.body.daysOfLife,
      currentPMA: req.body.currentPMA,
      currentWeight: req.body.currentWeight,
      visitType: req.body.visitType,
      ODExam: {
        plusODExam: req.body.plusODExam,
        zoneODExam: req.body.zoneODExam,
        ropODExam: req.body.ropODExam,
        ropODStage: req.body.ropODStage,
        categoryOD: req.body.categoryOD,
        apROPOD: req.body.apROPOD
      },
      OSExam: {
        plusOSExam: req.body.ropOSExam,
        zoneOSExam: req.body.zoneOSExam,
        ropOSExam: req.body.ropOSExam,
        ropOSStage: req.body.ropOSStage,
        categoryOS: req.body.categoryOS,
        apROPOS: req.body.apROPOS
      },
      FindingFollowUp: {
        ropFindings: req.body.ropFindings,
        followUpPlan: req.body.followUpPlan,
        nameOfExaminer: req.body.nameOfExaminer,
        followUpDate: req.body.followUpDate
      }
    }
  }
}
const options = {
  arrayFilters: [{ 'exam._id': new ObjectId(req.params.examID) }]
}

提示：您实际上不必在查询中进行$elemMatch。你可以做

const query = { "examinations._id": new ObjectId(req.params.examID) }

或者确保要更新正确的患者

const query = {
  "_id": new ObjectId(req.params.patientID),
  "examinations._id": new ObjectId(req.params.examID)
}
