使用mongoose寫一個集合的規(guī)則

• 首先要設計數(shù)據(jù)結構
• 下面是newGoods.json里面的一條數(shù)據(jù)

{"ID": "ff89cf2e14e143dc9e49ad75f7bc7bb0","GOODS_SERIAL_NUMBER": "6901844910651","SHOP_ID": "402880e860166f3c0160167897d60002","SUB_ID": "2c9f6c94609a62be0160a024fff1001d","GOOD_TYPE": 0,"STATE": 0,"IS_DELETE": 1,"NAME": "味好美番茄沙司(特惠裝)340gx2/份","ORI_PRICE": 15.5,"PRESENT_PRICE": 9.9,"AMOUNT": 10000,"DETAIL": '<div>Hi Mongoose</div>',"BRIEF": null,"SALES_COUNT": 0,"IMAGE1": "http://images.baixingliangfan.cn/shopGoodsImg/20180223/20180223091019_7384.jpg","IMAGE2": null,"IMAGE3": null,"IMAGE4": null,"IMAGE5": null,"ORIGIN_PLACE": null,"GOOD_SCENT": null,"CREATE_TIME": 1512208899918,"UPDATE_TIME": 1519725197992,"IS_RECOMMEND": 0,"PICTURE_COMPERSS_PATH": "http://images.baixingliangfan.cn/compressedPic/20180223091019_7384.jpg" }

• 1.導入mongoose
• 2.使用mongoose提供的Schema
• 3.設計的goodsSchema
• 4.暴露goodsSchema,供其他使用

const mongoose = require('mongoose'); const Schema = mongoose.Schema;const goodsSchema = new Schema({ID: { unique: true, type: String },GOODS_SERIAL_NUMBER: String,SHOP_ID: String,SUB_ID: String,GOOD_TYPE: Number,STATE: Number,NAME: String,ORI_PRICE: Number,PRESENT_PRICE: Number,AMOUNT: Number,DETAIL: String,BRIEF: String,SALES_COUNT: Number,IMAGE1: String,IMAGE2: String,IMAGE3: String,IMAGE4: String,IMAGE5: String,ORIGIN_PLACE: String,GOOD_SCENT: String,CREATE_TIME: String,UPDATE_TIME: String,IS_RECOMMEND: Number,PICTURE_COMPRESS_PATH: String }, {collections: 'Goods' })// 將建立的規(guī)則發(fā)布到model上面 mongoose.model('Goods', goodsSchema);

附:

• 模塊化
• 使用glob注冊schema目錄下,所有寫好的集合規(guī)則
• 假設以下文件寫在database/init.js中

const glob = require('glob'); const { resolve } = require('path');exports.initSchemas = () =>{glob.sync(resolve(__dirname, './schema', '**/*.js')).forEach(require); }

• 在入口文件index.js中導入并使用

const { initSchemas } = require('./database/init.js');(async () =>{initSchemas(); })
