Mongoose - 方法定义

• 定义Schema

let mongoose = require('mongoose'),Schema = mongoose.Schema;let UserSchema = new Schema({fullName: {// 姓名 PHARMACIST_FULLNAMEtype: String},sex: {// 性别 PHARMACIST_SEXtype: String,enum: ['男', '女']}
}, {timestamps: {createdAt: 'created', updatedAt: 'updated'}});

• 在methods上定义方法（Schema.methods.fn）

UserSchema.methods = {authenticate(plainPassword) {return this.password === this.hashPassword(plainPassword);},hashPassword: function (password) {if (this.salt && password) {return crypto.pbkdf2Sync(password, new Buffer(this.salt, 'base64'), 10000, 64, 'sha1').toString('base64');} else {return password;}}
};

• 使用方式，只能在 new Model() 得到的实例中才能访问
