Laravel use randomly created factory for relation

I’m trying to seed random belongsTo relationships for a Post, but they are all just being created with the same User and Community.

Code:

        $users = AppModelsUser::factory(100)
            ->create();

        $communities = AppModelsCommunity::factory(10)
            ->create();

        AppModelsPost::factory()
            ->for($users->random()->first())
            ->for($communities->random()->first())
            ->create();

After seeding, when I look at the database, the user_id and community_id is 1 for all of the posts.

How do I make it random for each seeded post based on the users and communities created beforehand?

Tried using random() but does not seem to take effect.

    I figured it out by using recycle method in the seeder and specifying a an id for each relationship in the factory.

    PostFactory:

        public function definition(): array
    {
        return [
            'user_id' => User::factory(),
            'community_id' => Community::factory(),
            'title' => fake()->sentence(),
            'created_at' => fake()->dateTimeThisMonth(),
        ];
    }

    New seeder code:

            $users = AppModelsUser::factory(100)
            ->create();

        $communities = AppModelsCommunity::factory(10)
            ->create();

        $posts = AppModelsPost::factory(100)
            ->recycle([$users, $communities])
            ->create();

    Works great now :D

    You can use a closure within a Sequence to generate random user_id and community_id for each post. For example:

    use IlluminateDatabaseEloquentFactoriesSequence;

$users = AppModelsUser::factory(100)->create();
$communities = AppModelsCommunity::factory(10)->create();

AppModelsPost::factory()
    ->count(50)
    ->state(new Sequence(
        fn (Sequence $sequence) => [
            'user_id' => $users->random()->id,
            'community_id' => $communities->random()->id,
        ]
    ))
    ->create();

    In case your code is exactly the same as the one you have provided, it is better to place the User and Community creation directly in the post factory.

    namespace DatabaseFactories;

use AppModelsUser;
use AppModelsCommunity;
use IlluminateDatabaseEloquentFactoriesFactory;

class PostFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array<string, mixed>
     */
    public function definition(): array
    {
        return [
            'user_id' => User::factory(),
            'community_id' => Community::factory(),
            'title' => fake()->sentence(),
            'created_at' => fake()->dateTimeThisMonth(),
        ];
    }
}
