Express 更新时追加值的续集

我试图使用

.update

方法将值附加到我的一个对象字段，但我的当前代码将字段（

组织.成员

）中的值替换为该字段在post方法期间捕获的新值。我在文档中查找附加值的方法（逗号分隔），但我没有看到任何与将值附加到对象属性相关的内容

这是我的路线：

var express = require('express');
var appRoutes   = express.Router();
var passport = require('passport');
var localStrategy = require('passport-local').Strategy;
var models = require('../models/db-index');

appRoutes.route('/settings')

    .get(function(req, res){
        models.Organization.find({
            where: {
                organizationId: req.user.organizationId
            }, attributes: ['organizationName','admin','members']
        }).then(function(organization){
            res.render('pages/app/settings.hbs',{
                user: req.user,
                organization: organization
            });
        })

    })

    .post(function(req, res, user){
        models.Organization.update({
            members: req.body.addMember
        },{ where: {
            organizationId: req.user.organizationId
        }}).then(function(){
            console.log("User added to Organization");
            res.redirect('/app/settings');
        });
    });

以下是组织模式：

module.exports = function(sequelize, DataTypes) {

var Organization = sequelize.define('organization', {
    organizationId: {
        type: DataTypes.INTEGER,
        field: 'organization_id',
        autoIncrement: true,
        primaryKey: true
    },
    organizationName: {
        type: DataTypes.STRING,
        field: 'organization_name'
    },
    admin: DataTypes.STRING,
    members: DataTypes.STRING
},{
    freezeTableName: true,
    classMethods: {
        associate: function(db) {
            Organization.hasMany(db.User, {foreignKey: 'user_id'});
        },
    },
});

    return Organization;
}

表格如下：

<div class="row">
    <div class="col-md-8 col-md-offset-2">
        <div class="annotation-form">
            <h2>Add User</h2>
            <form action="/app/settings" method="post">
                <input name="addMember" type="text" value="">
                <button type="submit">Add User</button>
            </form>
            <h2><u>Additional Users</u></h2>
            {{#each organization}}
                <li>{{this.members}}</li>
            {{else}}
                <p>No additional users</p>
            {{/each}}
        </div>
    </div>
</div>

我有一个类似的问题，在我的例子中，我使用的是mySQL和底层的

CONCAT

函数。 我不使用

+

连接字符串的原因是，如果字符串包含新行，则可能会出现SQL语法错误

 models.Organization.update({
            members:  Sequelize.fn('CONCAT', Sequelize.col("members"),req.body.addMember)
        },{ where: {
            organizationId: req.user.organizationId
        }}).then(function(){
            console.log("User added to Organization");
            res.redirect('/app/settings');
        });

 models.Organization.update({
            members:  Sequelize.fn('CONCAT', Sequelize.col("members"),req.body.addMember)
        },{ where: {
            organizationId: req.user.organizationId
        }}).then(function(){
            console.log("User added to Organization");
            res.redirect('/app/settings');
        });
