Fill a column automatically while you persist data to the database

If you want to fill a column automatically while you persist data to the database (e.g: slug) use Model Observer instead of hard code it every time

 1use Illuminate\Support\Str;
 2 
 3class Article extends Model
 4{
 5    ...
 6    protected static function boot()
 7    {
 8        parent:boot();
 9 
10        static::saving(function ($model) {
11            $model->slug = Str::slug($model->title);
12        });
13    }
14}
