如何创建具有“替代类型”的typescript接口的MongoBD模式？

interface User {
  name: string;
  email: string;
}

interface Admin {
  name: string;
  role: string;
}

type UserOrAdmin = User | Admin;

import mongoose from 'mongoose';

const userOrAdminSchema = new mongoose.Schema({
  // 使用discriminatorKey来区分不同的类型
  __t: { type: String, required: true },
}, { discriminatorKey: '__t' });

// 创建一个基类模型
const baseModel = mongoose.model<UserOrAdmin>('UserOrAdmin', userOrAdminSchema);

// 创建具体的模型
const userModel = baseModel.discriminator<User>('User', new mongoose.Schema({
  name: String,
  email: String,
}));

const adminModel = baseModel.discriminator<Admin>('Admin', new mongoose.Schema({
  name: String,
  role: String,
}));

userModel.find({}, (err, users) => {
  if (err) return handleError(err);
  console.log(users);
});
