Laravel 多态关联，中间表触发事件

laravel9 多态关联 使用 sync 更新时中间表没有触发事件

#posts
-id
-title

#videos
-id
-title
-url

#tags
-id
-name

#taggables
-tag_id
-taggable_id
-taggable_type

# Post Model
class Post extend Model
{
	public function tags(): MorphToMany
    {
        return $this->morphToMany(Tag::class, 'taggable')->using(Taggable::class);
    }
}

#Video Model
class Video extend Model
{
	public function tags(): MorphToMany
    {
        return $this->morphToMany(Tag::class, 'taggable')->using(Taggable::class);
    }
}

#Tag Model
class Tag extend Model
{
	
}

#Taggable Model
class Taggable extend MorphPivot
{
	public function tag(): BelongsTo
    {
        return $this->belongsTo(Tag::class);
    }
    
    protected static function booted()
    {
        static::created(function(self $taggable) {
            $taggable->tag?->increment('usage_count');
        });

        static::deleted(function (self $taggable) {
            $taggable->tag?->decrement('usage_count');
        });
    }
}

重点：在定义多态关系时使用 ->using(Taggable::class)
