This is a awesome example using a real-time upload with batch and Laravel Echo. Thank you for your article. 🎉

Just wrapping my head around batch and appreciate a lot that you are sharing your process here. Will most likely take some inspirations from your code. Thanks you!

Can someone help me out. I would like to log information in the callback functions of the Batch.

eg in the finally here

$batch = Bus::batch($jobs)
            ->finally(function () use ($transfer) {
                TransferCompleted::dispatch($transfer);
                // logger('finally I am HERE')
            })->dispatch();

But for me, that does not work. It can be because I totally fail to understand what is possible in there. Or I have a strage setup without knowig that.

Logging doesn't work at all in neither finally nor then or catch. And other things behave differently. Eg. $transfer->update() doesn't work - but $transfer->value = 'some value'; $transfer->save() does work.

I don't get it and I would like to understand what I am failing to understand. Happy for any hint :)

@ibes first what I got in my mind: try to pass $transfer variable by reference using &$transfer.

Maybe I do not understand your problem, but if you do $transfer->update() and it doest not updates the values set before finally - it could be cause of Model Serialization, and Laravel doest not serialise any "dirty" values of Model. So passing it by reference will already serialise a modified version of it.

Also please remember: finally will be called even if Batch will fail. So maybe you do not want to update your model in finally block.

This is super valuable. Thanks for sharing this, Philo :smiley:

Very new to the Laravel framework and tried to recreate this a few times (Laravel 9) but I get "Call to undefined method App\Models\User::transfers()" when the initiateTransfer() function in the Livewire component is called. Am I doing something obviously wrong?

[gavinsbtm]

Ok... I think I found a solution.

I'm trying this code with the fortress & jetstream user accounts & teams. I had to add the following code to the User model...

use Illuminate\Database\Eloquent\Relations\HasMany;

public function transfers(): HasMany
    {
    return $this->hasMany(Transfer::class);
    }

Hello Philo, I was having a hard time figuring out this error: Cannot assign string to property App\Http\Livewire\EditQuestion::$newFiles of type array.

Your Tip on typed public properties gave me the the solution. I had this: public array $newFiles = [];, changed it to public $newFiles = []; and the error went away.

Not sure why this happens.
