Periksa apakah nilai mengubah laravel

If you want to check if the model is dirty just call isDirty():

if($product->isDirty()){
    // changes have been made
}
Or if you want to check a certain attribute:

if($product->isDirty('price')){
    // price has changed
}

Pembaruan Laravel hanya mengubah bidang

protected function performUpdate(Builder $query, array $options = [])
{
    $dirty = $this->getDirty();

    if (count($dirty) > 0)
    {
        // runs update query
    }

    return true;
}
