推荐答案

在你的模型中，你可以添加一个 boot() 方法来管理这些事件.

Inside your model, you can add a boot() method which will allow you to manage these events.

例如，拥有 User.php 模型:

For example, having User.php model:

class User extends Model 
{

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

        self::creating(function($model){
            // ... code here
        });

        self::created(function($model){
            // ... code here
        });

        self::updating(function($model){
            // ... code here
        });

        self::updated(function($model){
            // ... code here
        });

        self::deleting(function($model){
            // ... code here
        });

        self::deleted(function($model){
            // ... code here
        });
    }

}
