php – Async Queues In Laravel

Posted by: admin July 12, 2020 Leave a comment

Questions:

I’m trying to implement Queuing, but the result is not async
And I have Applied the following

config/queue.php
'default' => env('QUEUE_DRIVER', 'database'),
    'connections' => [

    'sync' => [
        'driver' => 'sync',
    ],

    'database' => [
        'driver' => 'database',
        'table' => 'jobs',
        'queue' => 'default',
        'expire' => 60,
    ],
   ] 

and then applied the following commands
php artisan queue:table
php artisan migrate

and then run

php artisan queue:listen

and here is the functionality

SomethingController.php
   $model1 = new \App\Model1;
public function store(){
     Log::debug('before dispatch');
     $this->dispatch(new SendGiftCommand($model1));
     Log::debug('before dispatch');
     return true;
}



SendGiftCommand.php
{
    Log::debug('handle');
    SendGift::SendGiftAgedBased($this->model1);
    sleep(4);
    Log::debug('SendGiftCommand end');
}
SendGift.php
public static function SendGiftAgedBased(Model1 $model1){
  Log::debug('inside SendGiftAgedBased');
} 

even the process has worked but its not async, and it waits for the command to finish to return the response in the controller

And I git the Logs in this order

 [2015-12-09 16:28:42] local.DEBUG: before dispatch  
 [2015-12-09 16:28:42] local.DEBUG: handle  
 [2015-12-09 16:28:42] local.DEBUG: inside SendGiftAgedBased   
 [2015-12-09 16:28:46] local.DEBUG: SendGiftCommand end  
 [2015-12-09 16:28:46] local.DEBUG: after dispatch 

should it be working on Localhost ?

How to&Answers:

I had the same problem with jobs not being asynchronous and this worked for me :

  1. Edit .env and change the QUEUE_DRIVER setting from sync to database (editing config/queue.php wasn’t enough)
  2. Restart your processes

Answer:

In order for the job to be queued, the job class needs to implement Illuminate\Contracts\Queue\ShouldQueue interface – make sure it’s true for your class.

You can find more info on queuing jobs here: http://laravel.com/docs/5.1/queues#writing-job-classes

Answer:

Use this command to create the job:

   php artisan make:job SendGiftCommand --queued    

Refer this link for defining the job:

 https://laravel.com/docs/5.1/queues#writing-job-classes

Then pass declare the job and dispatch the job in this manner:

    $processGift = new sendGiftCommand($model1);
    $this->dispatch($processGift);

Also refer Supervisor Configuration on the above mentioned link further for continuously listening to the queue or automatically restarting the command queue:listen if they fail.
