Laravel Seeder Once

This library allows you to run your Laravel seeders only once.
No matter how many times artisan command db:seed is called. Done seeders will never be executed again.

How it works

Works similarly to migrations. First creates table in database, then logs all seeds that extend abstract class Kdabrow\SeederOnce\SeederOnce. In nutshell this will prevent to execute method run() if was executed in the past. Mechanism of logging data into database is heavily inspired by Laravel migration mechanism from package illuminate/database.

How to use it

1. Install it

By composer:

In Lumen do not forget to register provider in bootstrap/app.php

$app->register(Kdabrow\SeederOnce\Providers\SeederOnceProvider::class);

2. Create seeders table in database

Use this command:

php artisan db:install

This step is optional. Trait SeederOnce detects if table exists. If not, creates it automatically.

3. Extend seeders that you want to be run only once with SeederOnce

So result should look like this:

use Kdabrow\SeederOnce\SeederOnce;

class SomeSeeder extends SeederOnce
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        //
    }
}

This prevents to seed class SomeSeeder if was already seeded before.
Tip: Always replace class Seeder with SeederOnce. Otherwise, db:seed command might print unexpected results.

Configuration

Run seeder many times

It is possible to overwrite default functionality by change parameter $seedOnce to false:

use Kdabrow\SeederOnce\SeederOnce;

class DatabaseSeeder extends SeederOnce
{
    public bool $seedOnce = false;
    
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        //
    }
}

Such seeder will run like normal laravel seeder (as many times as called).

Configuration file

It is possible to publish configuration file:

php artisan vendor:publish --tag=seederonce.config

Table name

Default table name is: seeders

Console output

By default, seeder-once changes output of db:seed console command. Seeders that were run in the past will not be printed in the command output. It's possible to change that behaviour in configuration or by env variable:

SEEDER_ONCE_PRINT_OUTPUT=true

Output for already run seeders looks like this:

Database\Seeders\SomeSeeder was already seeded ..................... DONE

IMPORTANT NOTE ABOUT PREVIOUS VERSIONS

In previous versions SeederOnce was a trait. Because Laravel console output changed in version 9.21 I was forced to change trait into abstract class. If you want to keep using trait use seeder-once version 2.2. Only problem is that output from command db:seed is quite messy.
