# Egg-Sequelize-Auto

Automatically generate models for [egg-sequelize](https://github.com/eggjs/egg-sequelize) via the command line.

NOTE: Egg-Sequelize-Auto is based on [Sequelize-Auto](https://github.com/sequelize/sequelize-auto).

## Why Egg-Sequelize-Auto

[Sequelize-Auto](https://github.com/sequelize/sequelize-auto)
is a tool used to generate models for [Sequelize](https://github.com/sequelize/sequelize), which based on old `Sequelize` version 3.x.

Now, `Sequelize v4` has breaking changes, we need a latest version of `Sequelize-Auto` which works in [Egg](https://github.com/eggjs/egg).

So we upgraded `Sequelize-Auto` to `Sequelize` v4 and adjusted it for [egg-sequelize](https://github.com/eggjs/egg-sequelize).

## Install

npm install -g egg-sequelize-auto

## Prerequisites

You will need to install the correct dialect binding globally before using egg-sequelize-auto.

Example for MySQL/MariaDB

`npm install -g mysql2`

Example for Postgres

`npm install -g pg pg-hstore`

Example for Sqlite3

`npm install -g sqlite3`

Example for MSSQL

`npm install -g mssql`

## Usage

When installed `egg-sequelize-auto`, you could use both `egg-sequelize-auto` and `sequlize-auto`.

Usages are all the same, see [sequelize-auto's usage](https://github.com/sequelize/sequelize-auto#usage)

## Example

egg-sequelize-auto -o "./models" -d test -h localhost -u root -p root -x my_password -e mysql

Produces a file/files such as ./app/model/users.js which looks like:

/* indent size: 2 */

module.exports = app => {
const DataTypes = app.Sequelize;

const Model = app.model.define('Users', {
id: {
type: DataTypes.INTEGER(11),
allowNull: false,
primaryKey: true,
autoIncrement: true
},
username: {
type: DataTypes.STRING,
allowNull: true
},
touchedAt: {
type: DataTypes.DATE,
allowNull: true
},
aNumber: {
type: DataTypes.INTEGER(11),
allowNull: true
},
bNumber: {
type: DataTypes.INTEGER(11),
allowNull: true
},
validateTest: {
type: DataTypes.INTEGER(11),
allowNull: true
},
validateCustom: {
type: DataTypes.STRING,
allowNull: false
},
dateAllowNullTrue: {
type: DataTypes.DATE,
allowNull: true
},
defaultValueBoolean: {
type: DataTypes.BOOLEAN,
allowNull: true,
defaultValue: '1'
},
createdAt: {
type: DataTypes.DATE,
allowNull: false
},
updatedAt: {
type: DataTypes.DATE,
allowNull: false
}
}, {
tableName: 'Users',
freezeTableName: true
});

Model.associate = function (){

}

return Model;
};

## Configuration options

For the `-c, --config` option the following JSON/configuration parameters are defined by Sequelize's `options` flag within the constructor. For more info:

[http://docs.sequelizejs.com/class/lib/sequelize.js~Sequelize.html#instance-constructor-constructor](http://docs.sequelizejs.com/class/lib/sequelize.js~Sequelize.html#instance-constructor-constructor)

## Programmatic API

```js
const EggSequelizeAuto = require('egg-sequelize-auto')
const auto = new EggSequelizeAuto'database', 'user', 'pass');

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

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

// With options:
const auto = new EggSequelizeAuto('database', 'user', 'pass', {
host: 'localhost',
dialect: 'mysql'|'mariadb'|'sqlite'|'postgres'|'mssql',
directory: false, // prevents the program from writing to disk
port: 'port',
additional: {
timestamps: false
//...
},
tables: ['table1', 'table2', 'table3']
//...
})
```
