Sequelize 可不可以映射已存在的表？

Question

这是我模型的定义

const Sequelize = require('sequelize');
const sequelize = require('../../db/db_tp.js');

const manage_notice = sequelize.define('manage_notice', {
    nid: {type:Sequelize.INTEGER,primaryKey: true,autoIncrement: true},
    nname:Sequelize.STRING(20),
    nmaincolor:Sequelize.STRING(20),
    nothercolor:Sequelize.STRING(20),
    nshareicon:Sequelize.STRING(100),
    nsharetitle:Sequelize.STRING(30),
    nsharecontent:Sequelize.STRING(50),
  })

  manage_notice.sync({force: false}).then(function () {
    // Table created
    manage_notice.findAll().then(result => {
        
    })
    
  });

module.exports = manage_notice;

因为之前就有个有一定数据的表，但是每次映射的时候，都是因为表名重复新建了一个 尾巴加了s的表。

如果是这样的话，改表结构不是很麻烦吗？一开始就要想好所有字段结构？

Answer 1

const manage_notice = sequelize.define('manage_notice', {
       ...
}, {
     tableName: 'manage_notice'//指定表名
})
