Automatically delete files when a record is updated in table – Laravel

i have a table which has the fields attachment_id and file_path ,file_path field stores the path from s3 bucket corresponding to the attachment id .
is there any way to initialize a method or call an event directly from the model to delete file from s3 when the data in file_path field is updated or deleted ?

    Just create a method or helper inside or outside of that model which delete the file from S3 Bucket, then setup an observer to trigger it during updated or deleting

    e.i.

    On your model

    class WhatEver extends Model  {

    public function deleteS3File( $path ) {
        // Delete code here 
    }
}

    Then generate an Observer

    php artisan make:observer WhatEverObserver --model=WhatEver

    then you can call that method on updated and deleting event

    class WhatEverObserver  {

    // Runs when model is updated
    public function updated(WhatEver $whatEvah) {

        // Only trigger is file_path column is changed
        if ( $whatEvah->isDirty('file_path') ) {

            //Get the previous file_path record
            $oldPath = $whatEvah->getOriginal('file_path');

            //delete the previous file_path
            $whatEvah->deleteS3File( $oldPath );

        }
    }

    // Delete the file_path during model deletion
    public function deleting( WhatEver $whatEvah ) {
        $whatEvah->deleteS3File( $whatEvah->file_path );
    }
}

    You can use $dispatchesEvents.

    Create an event and then, in your model:

    class ClassName extends Model
{
    protected $dispatchesEvents = [
        'updated' => EventName::class
    ];
}
