Seeders & Factories

Seeders

namespace Database\Seeders;

use App\Models\User;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    public function run(): void
    {
        $this->call([
            CategorySeeder::class,
            PostSeeder::class,
        ]);

        User::factory()
            ->count(100)
            ->hasPosts(5)
            ->create();
    }
}

Model Factories

namespace Database\Factories;

use App\Models\User;
use Illuminate\Database\Eloquent\Factories\Factory;

class UserFactory extends Factory
{
    protected $model = User::class;

    public function definition(): array
    {
        return [
            "name" => fake()->name(),
            "email" => fake()->unique()->safeEmail(),
            "password" => bcrypt("password"),
            "is_active" => fake()->boolean(90),
        ];
    }

    public function admin(): static
    {
        return $this->state(fn (array $attrs) => [
            "is_admin" => true,
        ]);
    }
}

Factory Relationships

// Has many
User::factory()->hasPosts(3)->create();

// Belongs to
Post::factory()->for(User::factory()->admin())->create();

// Many to many
User::factory()->hasAttached(
    Role::factory()->count(2),
    ["assigned_at" => now()]
)->create();
