- schema创建一张表的数据结构 ~~~ const mongoose = require('mongoose'); const Schema = mongoose.Schema; //mixed可以存储任何类型的数据 const {ObjectId,Mixed} = Schema.Types.Mixed; const movieSchema = new Schema({ doubanId:{ unique:true, type:String }, category:[{ type:ObjectId, ref:'Movie' }], rate:Number, title:String, summary:String, video:String, poster:String, cover:String, rawTitle:String, movieTypes:[String], pubdate:Mixed, year:Number, tags:Array, meta:{ createdAt:{ type:Date, default:Date.now() }, updatedAt:{ type:Date, default:Date.now() } } }) mongoose.model('Movie',movieSchema) ~~~ - model 利用model函数发布这张表
