Getting Job Id in a Laravel queue with Database driver - php

Question

I have a laravel job which I create from a controller and some times i want to delete those jobs as the timings will be rescheduled
It is a notification job which sends notification one hour before a class and if the class is rescheduled i need to delete the jobs and insert new ones
my controller code is as below
$job = (new OnlineClassRemainderJob($remainder_data))->delay($value);
$id = dispatch($job);
array_push($job_ids, $id);
and the Job class is as shown below
<?php
namespace App\Jobs;
use App\Mail\OnlineClassRemainderMail;
use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Foundation\Bus\Dispatchable;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Queue\SerializesModels;
use Mail;
class OnlineClassRemainderJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $details;
/**
* Create a new job instance.
*
* #return void
*/
public function __construct($details)
{
$this->details = $details;
}
/**
* Execute the job.
*
* #return void
*/
public function handle()
{
Mail::to($this->details['email'])
->send(new OnlineClassRemainderMail($this->details));
}
}
Kindly show light how I can get the Job id so that i can save it in a database and in case of a reschedule i can remove all job ids related to that class and then dispatch new schedules
I can layout the scenario here
I am scheduling classes for example
I have a class on every day from 20th Jan to 25th Jan at 10 AM and I am scheduling a remainder mail sending job which will fire 1 hour before the class
But at certains scenario the Classes will be rescheduled and for that purpose i need to reschedule the remainders or delete and redispatch the jobs

Answer 1

you need to retrun job id from job with this function $this->job->getJobId();
class OnlineClassRemainderJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
/**
* Execute the job.
*
* #return void
*/
public function handle()
{
Mail::to($this->details['email'])
->send(new OnlineClassRemainderMail($this->details));
retrun $this->job->getJobId();
}
}
then
$job = (new OnlineClassRemainderJob($remainder_data))->delay($value);
$id = dispatch($job);
array_push($job_ids, $id);

Answer 2

To take the id of a job before executing it, e.g. to dequeue it before executing it.
$log = UpdateLog::create();
UpdateProduct::dispatch($log)->delay(now()->addMinutes(10));
$regex = 'UpdateLog.*?id\\\\";i:'.$log->id.';';
//delete or get job before start
DB::table('jobs')->where('payload','REGEXP',$regex)->delete();
my job example
//...
class UpdateProduct implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
/**
* #var UpdateLog
*/
protected $log;
/**
* Create a new job instance.
*
* #return void
*/
public function __construct(UpdateLog $log)
{
$this->log = $log;
}
//...
}
