Question

我正在开发MEAN堆栈应用程序，我在两个模式“ Supplier”和“ Brand”之间进行了关联，我了解如何在模型文件（mongo）中进行操作，但是现在我不知道该在服务器中做什么侧面和客户文件（视图）。当我添加新的供应商以更新供应商集合以及品牌集合时，我需要它。我对MEAN Stack很新鲜，请帮助我，我真的迷路了...

supplier.js

const mongoose = require('mongoose'),
Schema = mongoose.Schema,
Brand= require('../models/Brand');

var brandSchema = require('mongoose').model('Brand').schema;

const supplierSchema = mongoose.Schema({
suppliername: { type: String, required: true },
supplierPhone: { type: String },
supplierEmail: { type: String },
supplierAddress: { type: String },
brandSup: { type: brandSchema  , ref:'Brand'}
});

module.exports = mongoose.model('Supplier', supplierSchema);

brand.js

const mongoose = require('mongoose');

const brandSchema = mongoose.Schema({
   brandName: { type: String, required: true },
});

exports.brandSchema = brandSchema;
module.exports = mongoose.model('Brand', brandSchema);

suppliers.js

const express = require("express");
const Supplier = require('../models/supplier');

const router = express.Router();

router.post("", (req, res, next) => {
   const supplier = new Supplier({
     suppliername: req.body.suppliername,
     supplierPhone: req.body.supplierPhone,
     supplierEmail: req.body.supplierEmail,
     supplierAddress: req.body.supplierAddress,
     brandSub: req.body.brandSup,
  });
  supplier.save().then(createdSupplier => {
     res.status(201).json({
     message: 'supplier added successfully!',
     supplierId: createdSupplier._id
      });
    });
});

 router.get("", (req, res, next) => {
     Supplier.find().then(documents => {
       res.status(200).json({
       message: 'suppliers fetched successfully!',
       suppliers: documents
   });
  });
 });

router.delete("/:id", (req, res, next) => {
   Supplier.deleteOne({ _id: req.params.id }).then(result => {
      console.log(result);
      res.status(200).json({ message: "supplier Deleted!" });
     });
  });

   module.exports = router;

我不知道如何在关联两个架构后继续执行我的MEAN堆栈？
