```php
Route::get('/create', function() {
	Topic::forceCreate([
		'title' => 'This is a title',
		'slug' => str_slug('This is a title')
	]);
});
```

```php
Route::get('/create', function() {
	Topic::find(2)->update([
		'title' => 'This is another title',
		'slug' => str_slug('This is another title')
	]);
});
```


```php
class Topic extends Model
{
	public static function boot()
	{
		parent::boot();

		static::creating(function ($topic) {
			$topic->slug = str_slug($topic->titlejjj);
		});

		static::updating(function ($topic) {
			$topic->slug = str_slug($topic->titlejjj);
		});
	}
}
```

Now

```php
Route::get('/create', function() {
	Topic::forceCreate([
		'title' => 'This is a title'
	]);
});
```

```php
Route::get('/create', function() {
	Topic::find(2)->update([
		'title' => 'This is another title'
	]);
});
```
