Mongoose如何在数组内的对象中插入对象

const mongoose = require('mongoose');

const mySchema = new mongoose.Schema({
  myArray: [{
    name: String,
    age: Number
  }]
});

const MyModel = mongoose.model('MyModel', mySchema);

const newObject = {
  name: 'John',
  age: 25
};

MyModel.findOneAndUpdate(
  { _id: 'yourObjectId' }, // 根据条件找到对应的对象
  { $push: { myArray: newObject } }, // 使用$push操作符将新对象插入数组
  { new: true },
  (err, updatedObject) => {
    if (err) {
      console.error(err);
    } else {
      console.log(updatedObject);
    }
  }
);
