使用Factory进行一对一关系的Laravel种子

// database/factories/UserFactory.php
use App\Models\User;
use Faker\Generator as Faker;

$factory->define(User::class, function (Faker $faker) {
    return [
        'name' => $faker->name,
        'email' => $faker->unique()->safeEmail,
        'password' => bcrypt('password'),
    ];
});

// database/factories/ProfileFactory.php
use App\Models\Profile;
use Faker\Generator as Faker;

$factory->define(Profile::class, function (Faker $faker) {
    return [
        'bio' => $faker->paragraph,
        'location' => $faker->city,
    ];
});

// database/factories/UserFactory.php
use App\Models\Profile;

$factory->afterCreating(User::class, function ($user, $faker) {
    $profile = Profile::create([
        'user_id' => $user->id,
        'bio' => $faker->paragraph,
        'location' => $faker->city,
    ]);
});

// 在某个控制器或种子文件中
use App\Models\User;
use Illuminate\Database\Seeder;

class DatabaseSeeder extends Seeder
{
    public function run()
    {
        factory(User::class, 50)->create();
    }
}
