AdonisJS Seeder Generator

This package allows you easily generate seeder files for your AdonisJS app from existing Database table files!

Currently Supported

• MySQL
• SQLite
• PostgreSQL

Installation

You can install the package via composer:

npm install @shagital/adonisjs-seeder-generator

Or with yarn

yarn add @shagital/adonisjs-seeder-generator

Usage

Open start/app.js and add @shagital/adonisjs-seeder-generator/src/Commands/SeederGeneratorCommand to the commands array

• Note that you can replace the adonis with node ace if adonis is not installed globally on your system.

Basic usage

Will generate migration files for all tables in the DB set as default, and save files in database/seeds directory

adonis seed:generate

Specify tables to generate seeders for

adonis seed:generate  --include=table1,table2

Exclude specific tables

adonis seed:generate  --exclude=table1,table2

Specify DB connection to use

NOTE: Connection type must have been specified in config/databases

adonis seed:generate  --connection=mysql2

Save seeders files in specified path

NOTE: The package will attempt to create the specified directory if it doesn't exist

adonis seed:generate  --path=/var/www/html/backups

Truncate table before inserting.

This option is suitable for an application that hasn't gotten to production

NOTE: The table content will be wiped! ENSURE THE TABLE IS BACKED UP JUST IN CASE!!!

adonis seed:generate --force

Example Seeder file

'use strict';
