试图从morphMany关系中获取favited Item的值

Question

我的应用程序允许用户同时使用morphMany关系同时发布帖子和评论

最喜欢的型号：

public function favorited()
{
    return $this->morphTo();
}

public function user(){

    return $this->belongsTo(User::class, 'user_id');
}

我的特质

trait Favoriteable
{ 
  public function favorites()
 {
    return $this->morphMany(Favorite::class, 'favorited');
 }
}

我的帖子

public function favorites()
{
    return $this->morphMany(Favorite::class, 'favorited');
}

我的评论

public function favorites()
{
    return $this->morphMany(Favorite::class, 'favorited');
}

我的用户

 public function favorites(){
    return $this->hasMany(Favorite::class);
}

现在在刀片我试图让用户收藏的活动..我尝试了$活动 - ＆gt; subject-＆gt;收藏了更多没什么作用但是当我dd（$ activity-＆gt; subject-＆gt; favited）时我明白了：
