在redis队列上处理事务(Handle transactions on redis queue)

 我在一个函数中有多个任务，我使用函数中的事务 
 我想为这个事务性任务使用redis队列 
 例如，我有一个像下面这样的函数： 
 
 private function  check_destination_delivered($request,$id,$order)
{
    if ($request->get('status') == 'destination_delivered')
    {
      $this->destination_verification($request);
      DB::beginTransaction();
      try
      {
        $this->calculate_credit($id,$order);
        $this->calculate_customer_gift_credit($id,$order);
        DB::commit();
      }
      catch (\Exception $e)
      {
        DB::rollback();
        return $this->respondUnprocessable(1180,'error', $e);
      }
    }
}
 
 在这个功能我想要这一行  
$this->destination_verification($request);
 
 在事务开始之前运行，并在此之后：  
    $this->calculate_credit($id,$order);
    $this->calculate_customer_gift_credit($id,$order);
 
 使用redis队列计算几个小时后，并使用事务处理来完成每个任务，如果某些任务失败，则再次运行直到所有要完成的任务 

I have multiple tasks in a function and i use transaction in function 
 I want to use redis queue for this transactional tasks 
 For example i have a function like below : 
 
 private function  check_destination_delivered($request,$id,$order)
{
    if ($request->get('status') == 'destination_delivered')
    {
      $this->destination_verification($request);
      DB::beginTransaction();
      try
      {
        $this->calculate_credit($id,$order);
        $this->calculate_customer_gift_credit($id,$order);
        DB::commit();
      }
      catch (\Exception $e)
      {
        DB::rollback();
        return $this->respondUnprocessable(1180,'error', $e);
      }
    }
}
 
In this function i want to this line  
$this->destination_verification($request);
 
Run before transaction begin and after that this lines : 
    $this->calculate_credit($id,$order);
    $this->calculate_customer_gift_credit($id,$order);
 
Use redis queue to calculate a few hours later and use transaction to every task in there to be done and if some tasks be fail .queue run again until all tasks to be done

 你可以这样做  
    //seek_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
    android:id="@android:id/background"
    android:drawable="@drawable/seek_bar_background"/>
<item android:id="@android:id/progress"
    android:drawable="@drawable/seek_bar_progress" />
</layer-list>

//seek_bar_background.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<gradient
    android:angle="270"
    android:startColor="#8a8c8f"
    android:endColor="#58595b" />

    <clip android:drawable="@drawable/seek_bar_progress_fill" />
</item>

</layer-list>

//seek_bar_progress_fill.xml
<?xml version="1.0" encoding="UTF-8"?>

<gradient
    android:startColor="#b3d27e"       
    android:endColor="#93c044"

you can do it like this 
    //seek_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
    android:id="@android:id/background"
    android:drawable="@drawable/seek_bar_background"/>
<item android:id="@android:id/progress"
    android:drawable="@drawable/seek_bar_progress" />
</layer-list>

//seek_bar_background.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<gradient
    android:angle="270"
    android:startColor="#8a8c8f"
    android:endColor="#58595b" />

<corners android:radius="5dip" />

</shape>

//seek_bar_progress.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item
    android:id="@android:id/background"
    android:drawable="@drawable/seek_bar_background"/>
<item android:id="@android:id/progress">
    <clip android:drawable="@drawable/seek_bar_progress_fill" />
</item>

</layer-list>

//seek_bar_progress_fill.xml
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >

<gradient
    android:startColor="#b3d27e"       
    android:endColor="#93c044"
    android:angle="270"
 />
 <corners android:radius="5dip" />  

</shape>
