Node.js 更新在shell中工作但不在nodejs驱动程序中的查询

此查询在mongo shell中运行

db.orders.updateOne({ _id: ObjectId("5e26be38c13b7149d0a95111"),
"submittedTo":ObjectId("5e2555363405363bc4bf86c2") },
{ $set: {
    ... "vendorOrder" : [
    ...                 {
    ...                         "_id" : ObjectId("5e26be38c13b7149d0a95113"),
    ...                         "publicationCode" : "TOI",
    ...                         "publicationName" : "Times of India",
    ...                         "editionName" : "chennai city",
    ...                         "productCode" : "TCE1",
    ...                         "subscriptionCopies" : 70,
    ...                         "tradeCopies" : 9
    ...                 },
    ...                 {
    ...                         "_id" : ObjectId("5e26be38c13b7149d0a95112"),
    ...                         "publicationCode" : "ET",
    ...                         "publicationName" : "Economic Times",
    ...                         "editionName" : "chennai city",
    ...                         "productCode" : "ECE1",
    ...                         "subscriptionCopies" : 20,
    ...                         "tradeCopies" : 4
    ...                 }
    ...         ]}})

Mongo shell响应：

{“确认”：true，“匹配计数”：1，“修改计数”：1}

但它在nodejs中不起作用：以下是我迄今为止所做的尝试 查询1:

exports.editOrder = async (req, res, next) => {
  const { orderId, dealerId, vendorOrder } = req.body;
try {
    const orders = await Order.updateOne(
      {
        _id: orderId,
        submittedTo:dealerId
      },
      { $set: { vendorOrder } }
    );
 res.status(200).json({
      orders,
      message: "order submitted"
    });
  } catch (error) {
    res.send(error);
  }
};

const { orderId, dealerId, vendorOrder } = req.body;

      try {
        const orders = await Order.updateOne(
          {
            "_id": mongoose.Types.ObjectId(orderId),
            "submittedTo": mongoose.Types.ObjectId(dealerId)
          },
          { $set: { "vendorOrder": vendorOrder } }
        );

{
    "orders": {
        "n": 0,
        "nModified": 0,
        "ok": 1
    },
    "message": "order submitted"
}

查询2

exports.editOrder = async (req, res, next) => {
  const { orderId, dealerId, vendorOrder } = req.body;

  try {
    const orders = await Order.updateOne(
      {
        _id: mongoose.Types.ObjectId(orderId),
        submittedTo: mongoose.Types.ObjectId(dealerId)
      },
      { $set: { vendorOrder: vendorOrder } }
    );
 res.status(200).json({
      orders,
      message: "order submitted"
    });
  } catch (error) {
    res.send(error);
  }
};

查询3：带双“rest”的代码完全相同

exports.editOrder = async (req, res, next) => {
  const { orderId, dealerId, vendorOrder } = req.body;
try {
    const orders = await Order.updateOne(
      {
        _id: orderId,
        submittedTo:dealerId
      },
      { $set: { vendorOrder } }
    );
 res.status(200).json({
      orders,
      message: "order submitted"
    });
  } catch (error) {
    res.send(error);
  }
};

const { orderId, dealerId, vendorOrder } = req.body;

      try {
        const orders = await Order.updateOne(
          {
            "_id": mongoose.Types.ObjectId(orderId),
            "submittedTo": mongoose.Types.ObjectId(dealerId)
          },
          { $set: { "vendorOrder": vendorOrder } }
        );

{
    "orders": {
        "n": 0,
        "nModified": 0,
        "ok": 1
    },
    "message": "order submitted"
}

两点意见：

查询#2（或#3）是正确的-您应该始终使用

mongoose.Types.ObjectId（…）

将字符串转换为

ObjectId

，因为这两个字段都作为字符串存储在数据库中

代码的下一个问题是您的分解：

const{orderId，dealerId，vendorOrder}=req.body

当您的有效负载包含提交到

字段的

submittedTo

时，需要

dealerId

，因此您应该尝试：

const { orderId, submittedTo, vendorOrder } = req.body;

const orders = await Order.updateOne(
    {
        _id: mongoose.Types.ObjectId(orderId),
        submittedTo: mongoose.Types.ObjectId(submittedTo)
    },
    { $set: { vendorOrder: vendorOrder } }
);

哪个很好（请记住，

nModified

将作为

0

返回，如果

vendorOrder

变量和存储在数据库中的

vendorOrder

之间没有任何更改。

谢谢@mickl，但即使在编辑邮递员有效负载后，它仍然会给出相同的响应，尽管我更改了有效负载{“orderId”：“5e26be38c13b7149d0a95111”，“提交至”：“5e2555363405363bc4bf86c2”剩余有效载荷相同，但内部交易副本的变化除外vendorOrder@sachin我试过了，效果很好。你能粘贴你的

Order

schema吗？const orderSchema=new mongoose.schema（{vendoroder:[{publicationCode:{type:String}，publicationName:{type:String}，editionName:{type:String}，productCode:{type:String}，subscriptionCopies:{type:Number}，tradeCopies:{type:Number}]，提交到：{type:mongoose.Schema.Types.ObjectId}@mickl@sachin看起来不错。下面是我的工作示例：，请确保您连接到的数据库已包含集合和您尝试修改的文档（集合名称应为

orders

）我不知道我的代码有什么问题，我被困在这里面了，db里有相同id的文档，我在mongoshell用相同的查询修改了它，同样的id在问题中也是相同的
