Question

我有以下模型工厂：

 $factory->define(App\User::class, function (Faker $faker) {
   return [
      'first_name' => $faker->firstName,
      'last_name'  => $faker->lastName,
      'email' => $faker->unique()->safeEmail,
      'password' => 'secret', 
      'remember_token' => Str::random(10),
  ];
});

$factory->define(App\Order::class, function (Faker $faker) {
     return [
       'tax_id'  => 3,
       'total' => 0.00,
       'order_type' => 'Invoice'
    ];
});

$factory->define(App\OrderItem::class, function (Faker $faker) {
    return [
       'product_id' => 19,
       'product_name'  => 'Free product',
       'quantity' => 1,
       'item_price' => 0.00,
    ];
});

$factory->afterCreating(App\User::class, function ($user, $faker) {
     $user->orders()->save(factory(App\Order::class)->make());
});

$factory->afterMaking(App\Order::class, function ($order, $faker) {
     $order->orderItems()->save(factory(App\OrderItem::class)->make());
});

当我致电factory(App\User::class, 2)->create();时收到错误消息：

 Doctrine\DBAL\Driver\PDOException::("SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'order_id' cannot be null")

为什么这些回调方法不起作用，任何建议都值得赞赏？

我认为使用工厂而不是混合工厂和雄辩的做法会更清洁，因此可以正确使用description: "&" bounding_poly { vertices { x: 435 y: 959 } vertices { x: 459 y: 960 } vertices { x: 458 y: 990 } vertices { x: 434 y: 989 } } / afterCreating钩子：

afterMaking
