我有以下两个模式IndustryModel.js和userModel.js

industryModel.js

const mongoose = require("mongoose");

const industryTypeSchema = new mongoose.Schema({
  industryType: {
    type: String,// example-- Supplier,Customer,Company
    required: [true,"Please provide a industry type"],unique: true
  },module.exports = IndustryType = mongoose.model(
  "IndustryType",industryTypeSchema
);

userModel.js

const mongoose = require("mongoose");

const userTypeSchema = new mongoose.Schema({
  userType: {
    type: String,//  example--Manager,Engineer,Staff,Employee
    required: [true,"Please provide a user type"]
    unique: true  
  },industryType: {
    type: mongoose.Schema.ObjectId,ref: "IndustryType",required: [true,"Provide Indsutry Type"]
  }
});

userTypeSchema.pre(/^find/,function(next) {
  this.populate({
    path: "industryType",select: "industryType"
  });
  next();
});

module.exports = UserType = mongoose.model("UserType",userTypeSchema);

我的问题是我想创建的不是唯一的用户类型，而是与其行业类型相关的每个用户类型。 例如，有3种行业类型（供应商，客户，公司），我想为每三个行业（供应商，客户，公司）创建经理，但对于每个类似供应商的经理都有2个经理。

请帮助我如何实现此目标，或者我必须更改Schema。您的回应对我来说非常有价值，因为我的猫鼬并不新鲜
