Node.js 猫鼬鉴别器：NodeJS/Express

我已经使用Express开发了crudapi，在其中一个createapi中，我希望在请求体中提供的布尔标志的基础上扩展我的Mongoose模型模式

创建API主体（需要以这种格式存储在数据库中）：

{
  "name" : "John Doe",
  "admin" : true,
  "adminControl1" : "Some Control",
  "adminControl2" : "Some Other Control",
}

但我的MongoDB中存储的数据如下：

{
  "name" : "John Doe",
  "admin" : "true",
}

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

var options = { discriminatorKey: 'admin' }

var userSchema = new Schema({
  name: {
        type: String,
        required: true
  }
}, options);

const Event = mongoose.model('Event',userSchema);

const addedSchema = new mongoose.Schema({
  adminControl1 : {
    type: String
  },
  adminControl2 : {
    type: String
  },
},options);

const addedSchemaEvent = Event.discriminator(true,addedSchema);
module.exports = mongoose.model('Users', userSchema,'users');

我的模型文件如下：

{
  "name" : "John Doe",
  "admin" : "true",
}

const mongoose = require('mongoose');
const Schema = mongoose.Schema;

var options = { discriminatorKey: 'admin' }

var userSchema = new Schema({
  name: {
        type: String,
        required: true
  }
}, options);

const Event = mongoose.model('Event',userSchema);

const addedSchema = new mongoose.Schema({
  adminControl1 : {
    type: String
  },
  adminControl2 : {
    type: String
  },
},options);

const addedSchemaEvent = Event.discriminator(true,addedSchema);
module.exports = mongoose.model('Users', userSchema,'users');

鉴别器的第一个参数是新的型号名称

这是我的模型的一个例子

let Area: any = mongoose.model("Area", areaSchema);
let Country: any = Area.discriminator("Country", countrySchema);
let City: any = Area.discriminator("City", citySchema);

module.exports = {
   Area: Area,
   Country: Country,
   City: City,
};

其中areaSchema是基本模式，countrySchema和citySchema是添加的模式

我导入了这样的模型

const Area_ = require("../models/Area");
const Area = Area_.Area;
const City = Area_.City;
const Country = Area_.Country;

您可以共享整个model.js结构吗？我也应该导出事件吗？仍然无法通过。有什么秘密吗？
