eggjs中,自动从数据库直接生成model.

使用sequelize-auto可以自动生成models

https://www.npmjs.com/package/sequelize-auto

直接上命令就可以搞定了

# 安装必要的库
npm install -g sequelize-auto
# MySQL/MariaDB 数据库安装对应的库,其他数据库请看文档
npm install -g mysql
# 从命令行生成models
sequelize-auto -o './database/models' -h localhost -d databasename -u username -x password -p 3306 

将sequelize-auto与eggjs结合

安装必要的库

npm install -D sequelize-auto
npm install -D mysql

注意:安装参数为-D,是在开发模式使用.

写运行文件 ./database/autoModels.js

'use strict';

const SequelizeAuto = require('sequelize-auto');
const devConfig = require('../config/config.dev.js')();
const config = require('../config/config.default.js')({ name: '' });
const db = {
  database: devConfig.sequelize.database || config.sequelize.database,
  host: devConfig.sequelize.host || config.sequelize.host,
  port: devConfig.sequelize.port || config.sequelize.port,
  username: devConfig.sequelize.username || config.sequelize.username,
  password: devConfig.sequelize.password || config.sequelize.password,
  dialect: devConfig.sequelize.dialect || config.sequelize.dialect,
};

const auto = new SequelizeAuto(db.database, db.username, db.password, {
  host: db.host,
  dialect: db.dialect,
  directory: './database/models/', // prevents the program from writing to disk
  port: db.port,
  additional: {
    timestamps: false,
  },
  // tables: []  // 指定表格
  // ...
});

auto.run(function(err) {
  if (err) throw err;

  console.log(auto.tables); // table list
  console.log(auto.foreignKeys); // foreign key list
});

在package.json中添加启动执行项目

# 加入 "scripts" 段中.
"db:autoModels":"node ./database/autoModels"

执行命令,自动生成models

npm run db:autoModels

生成Models后可以根据里面的内容,稍作修改作为eggjs的model使用.
