Mongodb 修改子文档/深度嵌套文档时，Parent.save（）不起作用

我从整个收藏中发现我的文档如下：

    const account = await Account.findOne({ "buildings.gateways.devices.verificationCode": code })
    const buildings = account.buildings
    const gateways = buildings[0].gateways;
    const devices = gateways[0].devices;
    const device = _.filter(devices, d => d.verificationCode === code);

现在我想更改patientLastName的一个属性，然后保存整个文档。我正在做下面的事情

device.patientLastName = lastName;
const updated = await account.save();

这根本改变不了什么。我尝试过很多解决方案，但都不奏效。 不确定我是否可以像那样保存父文档

我很少有其他调用使用相同的代码，但唯一的变化是，这是在我的post调用中，而工作调用是在put调用中

我的模式：

const accountSchema = new mongoose.Schema({
  email: { type: String, unique: true, required: true },
  password: { type: String, required: true },
  userName: { type: String, unique: true, required: true },
  companyName: { type: String, required: true },
  apiKey: { type: String, unique: true, required: true },
  apiCallCount: { type: Number, default: 0 },
  solutionType: String,
  parentCompany: String,
  buildings:
    [
      new mongoose.Schema({
        buildingName: String,
        address: String,
        suite: String,
        floor: String,
        timeZone: String,
        gateways:
        [
          new mongoose.Schema({
            gatewayName: String,
            gatewayKey: { type: String, sparse: true },
            suite: String,
            devices: [
              new mongoose.Schema({
                serialNumber: { type: String, sparse: true },
                area: String,
                connectionStatus: Number,
                gatewayKey: String,
                applicationNumber: Number,
                firmwareVersion: String,
                needsAttention: Boolean,
                verificationCode: String,
                patientRiskStatus: String,
                patientFirstName: String,
                patientLastName: String
              }, { timestamps: true })
            ]
          }, { timestamps: true })
        ]
      }, { timestamps: true })
    ]
}, { timestamps: true });

更新： 我正在尝试： 它给我错误信息- 消息：将循环结构转换为JSON

  const updated = account.update(
    {
        "_id" : ObjectId(accountId),
        "buildings.gateways.devices.verificationCode": code
    }, 
    {
        "$set": { 
            "buildings.$.gateways.0.devices.0.patientFirstName": "name1", 
            "buildings.$.gateways.0.devices.0.patientLastName": "name2", 
        }
    }
)

谢谢你的帮助。谢谢

您可以使用

注意，我们还需要buildingId和gatewayId以使其动态工作

router.put("/account/:accountId/:buildingId/:gatewayId", async (req, res) => {
  const { patientFirstName, verificationCode } = req.body;
  try {
    let result = await Account.findByIdAndUpdate(
      req.params.accountId,
      {
        $set: {
          "buildings.$[building].gateways.$[gateway].devices.$[device].patientFirstName": patientFirstName
        }
      },
      {
        arrayFilters: [
          { "building._id": req.params.buildingId },
          { "gateway._id": req.params.gatewayId },
          { "device.verificationCode": verificationCode }
        ],
        new: true
      }
    );

    if (!result) return res.status(404);

    res.send(result);
  } catch (err) {
    console.log(err);
    res.status(500).send("Something went wrong");
  }
});

要使用验证代码123456更新设备patientFirstName，我们需要向url发送PUT请求http://..../account/5e0da052b4b3fe5188602e11/5e0da052b4b3fe5188602e12/5e0da052b4b3fe5188602e13

5e0da052b4b3fe5188602e11是帐户ID

5e0da052b4b3fe5188602e12是buildingId

5e0da052b4b3fe5188602e13是网关ID

请求机构：

{
    "verificationCode": "123456",
    "patientFirstName": "UPDATED!!!"
}

结果如下：

如果您始终希望在第一个网关的第一个建筑中进行更新，您可以使用以下方法：

router.put("/account/:accountId", async (req, res) => {
  const { patientFirstName, verificationCode } = req.body;
  try {
    let result = await Account.findByIdAndUpdate(
      req.params.accountId,
      {
        $set: {
          "buildings.0.gateways.0.devices.$[device].patientFirstName": patientFirstName
        }
      },
      {
        arrayFilters: [{ "device.verificationCode": verificationCode }],
        new: true
      }
    );

    if (!result) return res.status(404);

    res.send(result);
  } catch (err) {
    console.log(err);
    res.status(500).send("Something went wrong");
  }
});
