這是我模型的定義

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?yàn)橹熬陀袀€(gè)有一定數(shù)據(jù)的表，但是每次映射的時(shí)候，都是因?yàn)楸砻貜?fù)新建了一個(gè) 尾巴加了s的表。

如果是這樣的話，改表結(jié)構(gòu)不是很麻煩嗎？一開始就要想好所有字段結(jié)構(gòu)？
