如何将参数从播种者传递给工厂？

Question

我想将参数 ['site_id' => $site->id] 传递给 SiteMessage 工厂：

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;
use App\Models\SiteMessage;
use App\Models\Site;

class SitesMessagesTableSeeder extends Seeder
{
    /**
    * Run the database seeds.
    *
    * @return void
    */
    public function run()
    {
        Site::chunk(200, function ($sites) {
            foreach ($sites as $site) {
                SiteMessage::factory()->count(rand(2, 6))->create(['site_id' => $site->id]);
            }
        });
    }
}

如何在我的 SiteMessage 工厂中获取这些参数 class？

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;
use App\Models\SiteMessage;
use App\Models\Site;
use App\Models\Integration;

class SiteMessageFactory extends Factory
{
   
    protected $model = SiteMessage::class;

    public function definition()
    {
        return [
             **// Soliution: remove line below, it will be overridden automaticaly. \**
            'site_id'       => $arguments['site_id'], // Neet to use Id that I passed from seeder. 
            'integration_id'=> Integration::inRandomOrder()->first()->id,
            'type'          => rand(0,1) ? 'EMAIL' : 'SMS',
            'title'         => $this->faker->text($maxNbChars = 12),
            'description'   => $this->faker->sentence,
            'message'       => $this->faker->sentence,
            'enabled'       => 1,
            'created_at'    => now(),
            'updated_at'    => now(),
        ];
    }
}

在较旧的 Laravel 出厂版本中，我可以像这样在回调中传递它们：

$factory->define(SiteMessage::class, function (Faker $faker, array $arguments = []) {
//
});

但不知道如何使用新的 Class 工厂实现它。任何帮助将不胜感激:)

如您在有关 persisting models with factories 的 laravel 文档中所见，当您键入：

SiteMessage::factory()->count(rand(2, 6))->create(['site_id' => $site->id]);

SiteMessage 工厂的 site_id 属性将被您指定的 $site->id 覆盖。
