Laravel将数据从播种机传递到工厂

Question

我可以将数据从播种机传递到工厂吗？

我正在构建一个需要在开始时添加数据的应用程序

//seeder
public function run()
{
    $id = 0 //can i pass this var to factory?
    factory(App\VehicleCategory::class, 16)->create();
}

//factory
$factory->define(VehicleCategory::class, function (Faker $faker) {

$data = [
    'MICRO','SEDAN','CUV','SUV','MINIVAN','HATCHBACK','ROADSTER',
    'PICKUP','VAN','COUP'TRUCK','BIG TRUCK'
];

return [
    //
    'name' => $data[$id]
];
$id++;

});

我试图绕过这个也不能用

试图这样做，但总是返回相同的ID

$id = 0

$data = [
    'MICRO','SEDAN','CUV','SUV','MINIVAN','HATCHBACK','ROADSTER',
    'PICKUP','VAN','COUP'TRUCK','BIG TRUCK'
];


if(VehicleCategory::count() != 0){
    $id = VehicleCategory::latest()->first()->id;
}

return [
    //
    'name' => $data[$id]
];

我假设您要生成除工厂名称以外的随机数据，默认情况下只需保留工厂并覆盖'名称'

例如（使用默认的UserFactory Laravel附带）

然后在播种机中

public function run()
{
   $data = ['MICRO', 'SEDAN', 'CUV', 'SUV', 'MINIVAN', 'HATCHBACK', 'ROADSTER', 'PICKUP', 'VAN', 'COUP', 'TRUCK', 'BIG TRUCK'];

   foreach ($data as $name) {
      factory(User::class)->create(['name' => $name]);
   }
}

[
    {
        "id": 1,
        "name": "MICRO",
        "email": "[email protected]",
        "email_verified_at": "2019-09-29 17:49:36",
