Mahmoud SayedSeed Data
You use seeding to provide initial values for lookup lists,
for demo purposes, proof of concepts and of course for development.
To modules\custom\my_module\src we add a directory called SeedData. We add a file
called SeedDataGenerator.php to modules\custom\offer\src\SeedData.
The class will for now just create a dummy user.
<?php
namespace Drupal\my_module\SeedData;
use Drupal\user\Entity\User;
use Drush\Drush;
/**
* SeedDataGenerator.
*
* @package Drupal\my_module
*/
class SeedDataGenerator {
/**
* Function to create a seed data.
*
* @param string $entity
* The type of entity that needs to be created.
*
* @return null|int
* The number of entities created.
*/
public function generate(string $entity){
$count = 0;
switch ($entity) {
case 'user':
$count = $this->seedUser();
break;
}
return $count;
}
/**
* @return int
* The number of users created.
* @throws \Drupal\Core\Entity\EntityStorageException
*/
private function seedUser() {
$count = 0;
$user = User::create();
$user->setUsername('testUser');
$user->setPassword('P@ssw0rd');
$user->activate();
$user->enforceIsNew();
Drush::output()->writeln('<comment>Creating user test</comment>' );
if ($user->save()) {
$count++;
}
return $count;
}
}
Proceed with adding a drush command that will trigger the class:
Add custom/my_module/src/Commands/SeedGeneratorCommand.php and configure
further. The final file looks like this:
<?php
namespace Drupal\my_module\Commands;
use Drupal\my_module\SeedData\SeedDataGenerator;
use Drush\Commands\DrushCommands;
use Drush\Drush;
/**
* Class SeedGeneratorCommand.
*
* @package Drupal\my_module\Commands
*/
class SeedGeneratorCommand extends DrushCommands {
/**
* Runs the mymoduleCreateSeeds command.
*
* @command mymodule-create-seeds
* @aliases mymodulecs
* @usage drush mymodule-create-seeds
* Display 'Seed data created'
*/
public function mymoduleCreateSeeds():void {
$seed = new SeedDataGenerator();
$count = $seed->generate('user');
Drush::output()->writeln('<info>'. $count . ' user(s) created</info>' );
}
}
One more thing. Add a file custom/my_module/my_module.services.yml and add:
services:
offer.commands:
class: Drupal\offer\Commands\SeedGeneratorCommand
tags:
- { name: drush.command }
That’s it! Clear cache and see if our system has registered our command
$drush offer-create-seeds
