Question

我在一个函数中有多个任务，我在函数中使用事务
我想将redis队列用于此事务任务
例如，我有如下功能：

$this->destination_verification($request);

在这个功能中我想要这一行

    $this->calculate_credit($id,$order);
    $this->calculate_customer_gift_credit($id,$order);

在交易开始之前运行，之后运行：

List<BarEntry>

使用redis队列计算几个小时后，将事务用于完成的每个任务，如果某些任务失败，则再次运行，直到完成所有任务

I fix it by put function in queue like below :

class CreditJob extends Job implements ShouldQueue
{
use InteractsWithQueue, SerializesModels;

protected $order;
protected $trip;
protected $promotion;
protected $customer;

public function __construct($order,Order $trip,Customer $customer, Promotion $promotion)
{
  $this->order = $order;
  $this->trip = $trip;
  $this->promotion = $promotion;
  $this->customer = $customer;
}

 public function handle()
{
    $retry=0;
    $notDone=TRUE;
    DB::beginTransaction();
    while($notDone && $retry < 5)
    {
      try
      {
          $this->calculate_promotion($this->order);
          $this->calculate_credit($this->order);
          DB::commit();
          $notDone=FALSE;
      }
      catch (\Exception $e)
      {
          DB::rollback();
          $retry++;
          sleep(30);
      }
    }
    if($retry == 5)
    {
        $this->trip->fail_calculate_credit_and_promotion($this->order);
    }
} 

 }

If all the tasks not done .in queue loop running again
Is it right?
