I'm wanting to start using Sequelize, a module that allows ORM for mysql in node.js. I was wondering if it's possible to auto-generate the models like CakePHP does. In CakePHP, it will read the table's info, and automatically create the associations and fields with their types in the model. i'd really hate to have to completely map out all my tables by hand, as some are relatively large. Is there something out there that will do this for me? Or am I on my own to hand-type all the models out?

Sequelize provides methods to read the existing table names of a database. Furthermore there is a method to read the structure of a table. Combined, it should be possible to automate the creation of models.

Migrations, npx sequelize-cli model:generate --name User --attributes firstName:string using an automatically-managed transaction to ensure that all instructions are  Automatically generate bare sequelize models from your database. - nickel-js/sequelize-auto

You can use a sync method for each of model

example:

Object.keys(db).forEach((modelName) => {
    db[modelName].sync().then(result => {
       // some logic
    }).catch(err => {
       // some logic
    })
});

the logic will create a new table if the table not exist

full script index.js

'use strict';
const fs        = require("fs");
const path      = require("path");
const Sequelize = require("sequelize");

const sequelize = new Sequelize(process.env.DB_DATEBASE, process.env.DB_USER, process.env.DB_PASS, {
    host: process.env.DB_HOST,
    port: process.env.DB_PORT,
    dialect: 'mysql',
    operatorsAliases: false
});

const db = {};

fs
  .readdirSync(__dirname)
  .filter((file) => {
    return (file.indexOf(".") !== 0) && (file !== "index.js") && (file !== "migrations") && (file !== "redshift-migrations");
  })
  .forEach((file) => {
    const model = sequelize.import(path.join(__dirname, file));
    db[model.name] = model;
  });

Object.keys(db).forEach((modelName) => {
  if ("associate" in db[modelName]) {
    db[modelName].associate(db);
  }

  db[modelName].sync().then(result => {
    // some logic
  }).catch(err => {
    // some logic
  })
});

db.sequelize = sequelize;
db.Sequelize = Sequelize;

module.exports = db;

the script takes all files(models) in given directory where you will put the index.js file

Sequelize is a SQL ORM for Nodejs. ORM means Object-Relational Mapping. This type of interface offers you to take some distance from the database administration hassle. It will create the tables, the indexes and auto generate and execute the queries directly for you. You don’t have to execute those very painful and repetitive tasks.

Now you can use sequelize-automate to generate models automatically. sequelize-auto seems to be unmaintained for a long time, and the package is out-of-date.

$ npm install sequelize-automate
$ ./node_modules/.bin/sequelize-automate --help

For example:

$ ./node_modules/.bin/sequelize-automate -t js -h localhost -d test -u root -p root -o models

  • If you need to generatee them just once, you can use github.com/sequelize/sequelize-auto I tried it on my DB (mysql), and partly worked. It imported the structure, (columns and types), but I had to add keys and associations manually. Still better than nothing. Also for some reason it worked only when I run it on localhost (on db server). BUt that might be due to some issues with some firewalls, etc.
  • But can you tell me how can I save relations too (i.e Foreign key info).
  • Hi puneet gupta Please guide Me how to get the auto generate tables in db. I got a message from my command prompt Executing Done But when I verify the database There is nothing created inside please giude @Puneet gupta I stuck more than Two days
  • This is a life-saving tool. Don't waste your time creating model files with sequelize-cli if you already have your database schema.
  • Sequelizer is just a GUI frondend for sequelize-auto.
  • GREAT GUI for Sequelizer-auto which I didn't have time to fiddle with the command line, it kept giving me errors , but with this tool , it was quite easy and practical . good answer !
