Question

我需要根据对象字段对对象集合进行排序。 我已经看到许多类似的问题，但是没有一个解决方案有效。这就是我到目前为止所拥有的。

        $activities = collect();
        foreach(request()->user()->currentTeam->users as $user) {
        $activities->push(Activity::where('description', 'like', "%$query%")
            ->orWhere('properties->name', 'like', "%$query%")
            ->causedBy($user)->latest()->get()->load('causer'));
        }

       $flatActivities = $activities->collapse();

       $sorted = $flatActivities->sort(function($a, $b)
       {
           dd($a->id, $b->id);
           if ($a->id == $b->id) {
              return (0);
           }
           return (($a->id > $b->id) ? -1 : 1);
       });

除了上面具有的排序功能外，我还尝试过sortBy(id)和sortByDesc()，但都没有做任何事情。

现在，由于我正在查询每个用户的活动日志，因此它是基于该特定用户的latest活动进行排序的。理想情况下，我希望能够通过查询执行此操作，但是由于要获取每个用户的数据，因此我看不到这是怎么回事。

如果将集合转换为数组，我可以执行此操作，但是由于其他一些限制，我需要将其保留为对象集合。

请清楚，这是我的数据结构。

}

我需要按对象ID降序排列。

您可以在收藏夹中调用以下内容：

$sorted = $flatActivities->sortBy('order');

这将根据您在那里拥有的任何型号的订单字段以升序对其进行排序。

如果要按降序对其进行排序，请执行以下操作：

$sorted = $flatActivities->sortBy('order', SORT_REGULAR, true);`

按对象字段对对象的Laravel集合进行排序
