eggjs中,自动从数据库直接生成model.

使用sequelize-auto可以自动生成models

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.
