How to detect update event in model in Laravel 8

Good day to all The situation is as follows In the controller, in the update method, I try to update the object There is an image in the fields of this object Wrote a trait to process this field and load an image In the model itself, I called the update method, which just determines the event of updating the object The problem lies in the following image in the specified directory is loaded and the entry itself in the database does not change Here is my code

  1. Controller
  2. Model
  3. Trait

There is extra code in the model

public function update(Request $request, MainHeader $mainHeader): RedirectResponse
    {
        $mainHeader->update([
            'language_id' => $request->language_id,
            'brandLogoImage' => $request->file('brandLogoImage'),
            'homeTitle' => $request->homeTitle,
            'ourProjectsTitle' => $request->ourProjectsTitle,
            'contactTitle' => $request->contactTitle,
            'feedbackTitle' => $request->feedbackTitle,
        ]);
        return redirect()->route('admin.header.index')->with('success', 'Данные успешно обновлены');
    }

public function setBrandLogoImageAttribute($value): string
    {
        return $this->uploadImage('brandLogoImage', $value);
    }

    public function update(array $attributes = [], array $options = [])
    {
        $this->uploadImage('brandLogoImage', $attributes['brandLogoImage']);
        $this->setBrandLogoImageAttribute($attributes['brandLogoImage']);
        return parent::update($attributes, $options); // TODO: Change the autogenerated stub
    }

protected function uploadImage(string $attr, $value): string
    {
        $uploadDir = public_path('uploads/');
        $imageDir = public_path('uploads/image/');
        if (!file_exists($uploadDir)){
            mkdir($uploadDir);
        }
        if (!file_exists($imageDir)){
            mkdir($imageDir);
        }
        if (!file_exists(public_path("uploads/image/$this->table/"))){
            mkdir(public_path("uploads/image/$this->table/"));
        }
        $imageName = Str::random(12) . '.png';
        Image::make($value)->save(public_path("uploads/image/$this->table/$imageName") , 100);
        return $this->attributes[$attr] = (string) "uploads/image/$this->table/$imageName";
    }

if you call the update methode in your model then you are overriding the default update() of the model class , its not listening to the event it simply runs your code before parent:: , so you need to make sure that the changes you are making does not get overwitten by the parent call .

regarding your question on how to detect update , if you want to perform anything before update than i advise you to use eloquent events or use observers , Observers listen to various events regarding your model like updating or updated .. but i think if its only for updating event than you should use event using closure

for example :

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    /**
     * The "booted" method of the model.
     *
     * @return void
     */
    protected static function booted()
    {
        static::updating(function ($user) {
            // do what you want
        });
    }
}

If your pupose
