Laravel Auditing Not Logging old_values and new_values When Using Observer

Question

I'm working with Laravel Filament where I'm using audits package for audits the activity of laravel model. I've laravel model like:

<?php

namespace App\Models;

use App\Casts\Money;
use App\Observers\InventoryObserver;
use Illuminate\Database\Eloquent\Attributes\ObservedBy;
use Illuminate\Database\Eloquent\Builder;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Illuminate\Database\Eloquent\Relations\HasOne;
use Illuminate\Database\Eloquent\SoftDeletes;
use OwenIt\Auditing\Contracts\Auditable;

#[ObservedBy(InventoryObserver::class)]
class Inventory extends Model implements Auditable
{
    use \OwenIt\Auditing\Auditable;
    use HasFactory, SoftDeletes;

    protected $guarded = [];
}

And InventoryObserver.php

<?php

namespace App\Observers;

use App\Events\RefreshInventories;
use App\Events\RefreshProducts;
use App\Models\Inventory;
use App\Services\TaxCalculatorService;

class InventoryObserver
{
   public function created(Inventory $inventory): void
    {
        if ($inventory->gross_amount) {
            $taxCalculatorService = TaxCalculatorService::make($inventory->gross_amount, $inventory->tax_rate);

            $inventory->net_amount = $taxCalculatorService->getNetAmount();
            $inventory->tax_amount = $taxCalculatorService->getTaxAmount();

            $inventory->saveQuietly();
        }

        $inventory->machine->updateStockPercentage();
    }

    public function updated(Inventory $inventory): void
    {
        if ($inventory->isDirty(['gross_amount', 'tax_rate'])) {
            $taxCalculatorService = TaxCalculatorService::make($inventory->gross_amount, $inventory->tax_rate);

            $inventory->net_amount = $taxCalculatorService->getNetAmount();
            $inventory->tax_amount = $taxCalculatorService->getTaxAmount();

            $inventory->saveQuietly();

            //            RefreshProducts::broadcast($inventory->machine);
        }

        if ($inventory->isDirty('quantity', 'max_quantity')) {
            $inventory->machine->updateStockPercentage();

            //            RefreshInventories::broadcast($inventory->machine);
        }
    }

When I'm saving values from form it's auditing the values in audits database table with empty values inside old_values and new_values.

Can anyone help me how can I solve this problem?

Thanks...

I think because of saveQuietly(). Because it suppresses all events ( updating, updated) as I remember.

Try using

$inventory->save(); # doubt check for infinity loop inside `update`

If you must use saveQuietly() but still want auditing, then use this manually

$inventory->setAuditEvent('updated');
$inventory->audit();

I must need to use saveQuietly(). I've use your code but I got error like: Call to undefined method App\Models\Inventory::audit() . I've already added Audit trait and all on Inventory model. I've done code like: $inventory->saveQuietly();$inventory->setAuditEvent('updated');$inventory->audit();
