Laravel 8 动态模型工厂

使用Laravel 8的动态模型工厂，我们可以更加灵活地生成测试数据，提高开发效率。动态模型工厂是Laravel 8引入的新功能，它允许我们根据模型的字段类型自动生成合适的测试数据。

php
use Illuminate\Database\Eloquent\Factories\Factory;
use App\Models\User;
class UserFactory extends Factory
{
    protected $model = User::class;
    public function definition()
    {
        return [
            'name' => $this->faker->name,
            'age' => $this->faker->numberBetween(18, 60),
        ];
    }
}

php
use Illuminate\Database\Seeder;
use App\Models\User;
class UserSeeder extends Seeder
{
    public function run()
    {
        User::factory()->count(10)->create();
    }
}
