node orm sequelize model-table 互相生成

经过比较个人感觉sequelize 比其他orm好用些，用了半天时间终于搞定了，直接上代码

1、利用sequelize    model生成table

applicationMysql.js文件－－－－－－－－－－－－

var Sequelize = require('sequelize');
var sequelize = new Sequelize('db', 'root', 'root', {
  host: 'localhost',
  dialect: 'mysql',
  pool: {
    max: 5,
    min: 0,
    idle: 10000
  },
  Sequelize :Sequelize
});

function ApplicationMysql(){
    return sequelize;
}
module.exports = new ApplicationMysql();

user.js文件－－－－－－－－－－－－－－－－－

var app = require('../server/applicationMysql.js');
User = app.define('user',{
  firstName: {
    type: app.Sequelize.STRING,
   // field: 'first_name' // Will result in an attribute that is firstName when user facing but first_name in the database
  },
  lastName: {
    type: app.Sequelize.STRING
  }
},{
freezeTableName: true // Model tableName will be the same as the model name
});

app.sync().then(function() {
User.create({
    first_name: 'qi',
    lastName: 'shuo'
   });
});

module.exports = User;

加载var userModel = require('./user.js');数据库中就会生成user表

详见http://docs.sequelizejs.com/en/v3/

2、利用sequelize－auto　  table生成model

在数据库新建表

然后运行sequelize-auto -o "./mysqltest" -d db -h localhost -u root -p 3306 -x root -e mysql

在mysqltest目录下就会生成user.js

/* jshint indent: 2 */
module.exports = function(sequelize, DataTypes) {
  return sequelize.define('user', {
    id: {
      type: DataTypes.INTEGER(11),
      allowNull: false,
      primaryKey: true,
      autoIncrement: true
    },
    first_name: {
      type: DataTypes.STRING,
      allowNull: true
    },
    lastName: {
      type: DataTypes.STRING,
      allowNull: true
    },
    type: {
      type: DataTypes.STRING,
      allowNull: true
    },
    createdAt: {
      type: DataTypes.DATE,
      allowNull: false
    },
    updatedAt: {
      type: DataTypes.DATE,
      allowNull: false
    }
  }, {
    tableName: 'user'
  });
};

好了，有了这个写代码爽多了
