Detecting if a job has been dispatched using dispatchNow - php

Question

I have a job that under certain circumstances calls another job
<?php namespace App\Jobs;
use App\Models\Account;
class EnqueueScheduledDownloads implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
protected $account;
public function __construct(Account $account)
{
$this->account = $account;
}
public function handle()
{
foreach($this->account->pending_downloads as $file)
{
DownloadFile::dispatch($file);
}
}
}
While the download job is usually executed in a queue; there are times, for example during testing, where it would make my life much easier if the whole chain was processed synchronously in a blocking fashion. I would like to be able to do something like this:
public function handle()
{
foreach($this->account->pending_downloads as $file)
{
if($this->getDispatchMode() == 'sync') {
DownloadFile::dispatchNow($file);
} else {
DownloadFile::dispatch($file);
}
}
}
Is this possible?

Answer 1

After a bit of poking around I was able to answer my own question. Yes it is possible; if a job is dispatched via dispatchNow() the job property of the Queueable object will be null, whereas if it is dispatched on a connection using dispatch() it will be set to an implementation of Illuminate\Contracts\Queue\Job. So the handle method can be changed as such:
public function handle()
{
foreach($this->account->pending_downloads as $file)
{
if(is_null($this->job)) {
DownloadFile::dispatchNow($file);
} else {
DownloadFile::dispatch($file);
}
}
}
And it will work as expected. I was able to find this solution by creating a new job:
<?php namespace App\Jobs;
class TestJob implements ShouldQueue
{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
public function __construct()
{
}
public function handle()
{
dump(get_object_vars($this));
}
}
and dispatching it on various queue and connections as well as with dispatchNow() and observing the output. Furthermore it is possible to retreive the connection and queue the job was dispatched on from the $this->job:
public function handle()
{
echo $this->job->getConnectionName();
echo $this->job->getQueue();
}
