Question

我正在阅读laravel softdelete并在此恢复级联：Laravel 5: cascade soft delete

用户说：

You should use Eloquent events for this.

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

他没有提到放置此代码的位置，我有兴趣收听雄辩删除和恢复的事件。我在哪里可以放这个代码？我可以在模型课中听吗？如果不在哪里放置它？

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();
        }
    });

}

或者示例：

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();
   }
}

雄辩的事件，我可以在模型类中使用它们吗？
