nodejs / mongoDb：在一个请求中更新许多字段

Question

如何更新多个 orderStatus 而不是只更新一个？

request.body.type默认为字符串，只包含一种类型；

当 isCompleted 的类型变为真时，我什至想要之前的枚举索引 isCompleted 变为真

有可能还是我需要在前端进行修改？

这里是代码

const orderSchema = new mongoose.Schema(
  {
    user: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "User",
      required: true,
    },
    orderStatus: [
      {
        type: {
          type: String,
          enum: ["ordered", "packed", "shipped", "delivered"],
          default: "ordered",
        },
        date: {
          type: Date,
        },
        isCompleted: {
          type: Boolean,
          default: false,
        },
      },
    ],
  }

exports.updateOrder = (req, res) => {
  Order.updateOne(
    { _id: req.body.orderId, "orderStatus.type": req.body.type },
    {
      $set: {
        "orderStatus.$": [
          { type: req.body.type, date: new Date(), isCompleted: true },
        ],
      },
    }
  ).exec((error, order) => {

嘿，你可以使用 updateMany() 操作

db.collection.updateMany(
   <query>,
   { $set: { status: "D" }, $inc: { quantity: 2 } },
   ...
)
