How to use queue an event in laravel 5.2? - events

Question

I am using event to delete particular information.
I have DeleteCourseConfirmation event listener and DeleteBranchCourse event.
It works fine.
Here is the code for DeleteBranchCourse event
class DeleteBranchCourse extends Event{
use SerializesModels;
private $fee;
private $feeId;
public function __construct($fee,$feeId)
{
$this->fee=$fee;
$this->feeId=$feeId;
}
/**
* Get the channels the event should be broadcast on.
*
* #return array
*/
public function broadcastOn()
{
return [];
}
public function deleteCourse()
{
$this->fee->destroy($this->feeId);
}}
Here is the code for DeleteCourseConfirmation event listener
class DeleteCourseConfirmation{
public function __construct()
{
}
public function handle(DeleteBranchCourse $event)
{
$event->deleteCourse();
}}
But when i tried php artisan queue:listen after implementing ShouldQueue interface in DeleteCourseConfirmation to queue event listeners
class DeleteCourseConfirmation implements ShouldQueue{
use InteractsWithQueue;
public function __construct()
{
}
public function handle(DeleteBranchCourse $event)
{
$event->deleteCourse();
}}
an error occurs.
No query results for model [App\Modules\Branch\Models\Fee]
I am following Laravel 5.2 documentation Queued Event Listeners

Found the solution.
First i changed the Event fire code
Event::fire(new DeleteBranchCourse($fee,$feeId));
to
Event::fire(new DeleteBranchCourse($feeId));
Because i don't need to send Fee model's object to DeleteBranchCourse's constructor.
and i change DeleteBranchCourse class to this
class DeleteBranchCourse extends Event{
use SerializesModels;
private $feeId;
public function __construct($feeId)
{
$this->feeId=$feeId;
}
/**
* Get the channels the event should be broadcast on.
*
* #return array
*/
public function broadcastOn()
{
return [];
}
public function deleteCourse()
{
Fee::destroy($this->feeId);
}}
And finally running this command from terminal
php artisan queue:listen
or changing the handle function of listeners class to this
public function handle(DeleteBranchCourse $event)
{
$this->attempts($event->deleteCourse());
}}
