模型事件不工作

Question

我有以下型號：

class ProjectTwitterStatus extends Eloquent { 

    protected $table = 'project_twitter_statuses'; 

    protected $softDelete = true; 

    protected $guarded = array('id'); 

    public static function boot() 
    { 
     parent::boot(); 

     ProjectTwitterStatus::deleting(function($projectTwitterStatus) 
     { 
      $projectTwitterStatus->deleted_by = Auth::user()->id; 
     }); 
    } 

    public function twitterStatus() { 
     return $this->belongsTo('TwitterStatus'); 
    } 

    public function twitterRetweet() { 
     return $this->belongsTo('TwitterRetweet','twitter_status_id','twitter_status_id'); 
    } 

    public function project() { 
     return $this->belongsTo('Project'); 
    } 
} 

某處在我的應用程序中的項目是使用下面的語句之一刪除：

ProjectTwitterStatus::find($id)->delete(); 
ProjectTwitterStatus::whereIn('twitter_status_id', $twitterStatusIds)->delete(); 

我可以在數據庫中的項目看已被（軟）刪除。但是，deleted_by列未填充。

有誰知道我在做什麼錯？

嘗試使用Late Static Binding，像以下事項

class ProjectTwitterStatus extends Eloquent { 

    public static function boot() 
    { 
     parent::boot(); 

     static::deleting(function($projectTwitterStatus) 
     { 
      $projectTwitterStatus->deleted_by = Auth::user()->id; 
     }); 
    } 

}
