使用mongoose进行“独立工作收入员工”模式设计的问题

const mongoose = require('mongoose');

// 定义员工模型
const EmployeeSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  position: {
    type: String,
    required: true
  },
  // 其他员工相关属性...
});

// 定义独立承包商模型
const ContractorSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  specialization: {
    type: String,
    required: true
  },
  // 其他独立承包商相关属性...
});

// 定义公司模型
const CompanySchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  employees: [EmployeeSchema], // 员工列表
  contractors: [ContractorSchema], // 独立承包商列表
  // 其他公司相关属性...
});

// 创建模型
const Employee = mongoose.model('Employee', EmployeeSchema);
const Contractor = mongoose.model('Contractor', ContractorSchema);
const Company = mongoose.model('Company', CompanySchema);
