Informations about the package seeder-once
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:
php | laravel / lumen | seeder-once |
---|---|---|
8.2, 8.3, 8.4 | 12.0 | |
8.2, 8.3 | 10.0, 11.0 | |
8.1, 8.2 | 10.0 | |
8.0, 8.1 | 9.21 | |
7.3, 7.4, 8.0 | 8.0, 9.0 | |
7.2, 7.3, 7.4, 8.0 | 6.0, 7.0 |
In Lumen do not forget to register provider in bootstrap/app.php
2. Create seeders table in database
Use this command:
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:
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:
Such seeder will run like normal laravel seeder (as many times as called).
Configuration file
It is possible to publish configuration file:
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:
Output for already run seeders looks like this:
