How to pass array parameter from seeder into Factory? – Laravel

In laravel 9 app I need to create dummy data with factory with aften repeating url for using in groups. So in seeder I have :

{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $itemsCount = 50;
        $faker = FakerFactory::create();
        $refUrls = [];

        for ($i = 0; $i < (int) ($itemsCount / 5); $i++) {
            $refUrls[] = $faker->url(); // I generate such array
        }

        BannerClickedCount::factory()
            ->count($itemsCount)
            ->create(['refUrls'=> $refUrls]);

and pass it to factory as parameter, but it does not work as BannerClickedCount model has no refUrls field and I can not use it as passed
parameter into database/factories/BannerClickedCountFactory.php:

class BannerClickedCountFactory extends Factory
{
    /**
     * The name of the factory's corresponding model.
     *
     * @var string
     */
    protected $model = BannerClickedCount::class;
    
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition($refUrls = []) // That is empty array
    {
        Log::info(varDump($refUrls, ' -1 extends Factory $refUrls::'));
        ...

How can I pass array parameter from seeder into Factory ?

ADDTIVE CODE :
I tried to modify my code, but got error :

  current(): Argument #1 ($array) must be of type array, string given

  at database/seeders/banner_clicked_countsWithInitData.php:32
     28▕         }

     36▕         /* BannerClickedCount::factory()

  1   database/seeders/banner_clicked_countsWithInitData.php:32

ADDTIVE CODE # 2:

$refUrls in my code is an array of strings :

$refUrls[] = $faker->url();

So I think I do not need explode be used, but with I remade seeder file :

$itemsCount = 10;
$faker           = FakerFactory::create();
$refUrls = [];
for($i = 0; $i< (int)($itemsCount/2) ; $i++) {
    $refUrls[] = $faker->url();
}
Log::info(varDump($refUrls, ' -1 RUN Factory $refUrls::'));

BannerClickedCount::factory()->count($itemsCount)
    ->state(new Sequence(
        current($refUrls),
        $refUrls
    ))
    ->create([]); // Error pointing at this line !

I got error :

  array_merge(): Argument #2 must be of type array, string given

  at vendor/laravel/framework/src/Illuminate/Database/Eloquent/Factories/Factory.php:438
    434▕             if ($state instanceof Closure) {

  ➜ 438▕             return array_merge($carry, $state($carry, $parent));

    I salved the isue with defining custom method setRefUrl in factory :

    class BannerClickedCountFactory extends Factory
{
    protected $model = BannerClickedCount::class;

    public function definition($refUrls = [])
    {
        $locales = config('translatable.locales', []);
        return [
            'banner_id' => $this->faker->randomElement(Banner::all())['id'],
            'locale' => $this->faker->randomElement($locales),
            'user_id' => $this->faker->randomElement([1, 2, 3, 4, 5]),
            'ip'        => '127.0.0.1',
            'created_at' => $this->faker
                ->dateTimeBetween('-1 week', '-1 minute')
                ->format('Y-m-d G:i'),
        ];
    }
    public function setRefUrl($refUrls)
    {
        return $this->state(function (array $attributes) use($refUrls) {
            return [
                'ref_url' => $this->faker->randomElement($refUrls)
            ];
        });
    }

    and calling it in the seeder :

    $itemsCount = 200;
$faker           = FakerFactory::create();
$refUrls = [];
for($i = 0; $i< (int)($itemsCount/20) ; $i++) {
    $refUrls[] = $faker->url();
}
BannerClickedCount::factory()->count($itemsCount)->setRefUrl($refUrls)

    modify the definition method of your BannerClickedCountFactory class to accept an additional parameter that will receive the array of reference URLs. And in your seeder, you can pass the $refUrls array to the BannerClickedCountFactory.

    class BannerClickedCountFactory extends Factory
{
    // ...

    /**
     * Define the model's default state.
     *
     * @param array $refUrls
     * @return array
     */
    public function definition(array $refUrls = [])
    {
        return [
            // define the default state of your model
            'ref_url' => count($refUrls) > 0 ? array_shift($refUrls) : null,
            // other fields...
        ];
    }
}

    Seeder

    BannerClickedCount::factory()
    ->count($itemsCount)
    ->state(new Sequence(
        // generate a sequence of reference URLs from the array
        fn () => current(explode(',', $refUrls)),
        $refUrls
    ))
    ->create();
