雄辯的事件，我可以在模型類中使用它們嗎？

Question

我對laravel softdelete閱讀，此處恢復級聯：Laravel 5: cascade soft delete

其中一個用戶說：

You should use Eloquent events for this. 

Offers::deleted(function($offer) { 
    $offer->services()->delete(); 
}); 
Offers::restored(function($offer) { 
    $offer->services()->withTrashed()->restore(); 
}); 

他沒有提到在何處放置此代碼，我感興趣的監聽雄辯刪除，恢復活動。我可以在哪裏放這個代碼？我可以在模特班聽嗎？如果不放在哪裏呢？

Answer 1

我想......

<?php 
class Attribute extends Model implements Transformable 
{ 
//.... 
protected static function boot() { 
    parent::boot(); 

    static::deleting(function($model) { 
     foreach ($model->attributeValue()->get() as $attributeValue) { 
      $attributeValue->delete(); 
     } 
    }); 

} 

或者例如：

class BaseModel extends Model 
{ 
    public static function boot() 
    { 
     static::creating(function ($model) { 
     // blah blah 
     }); 

     static::updating(function ($model) { 
     // bleh bleh 
     }); 

     static::deleting(function ($model) { 
     // bluh bluh 
     }); 

     parent::boot(); 
    } 
}
