如何限制Laravel中的通知数量

Question

我尝试过->limit(4)方法，但这似乎不起作用

@foreach(auth()->user()->unreadNotifications()->limit(4) as $notification)
    <li>
        <a href="profile.html">
           <div>
              {{ $notification->data['message'] }}<span class="pull-right text-muted small">{{ time_elapsed_string($notification->created_at) }}</span>
           </div>
        </a>
    </li>
@endforeach

Answer 1

您不在此处执行查询：

@foreach(auth()->user()->unreadNotifications()->take(4)->get() as $notification)

此外，您不应在Blade文件中运行查询 。

Answer 2

很难说unreadNotifications真的会返回什么，但如果是它的集合你可以使用：

@foreach(auth()->user()->unreadNotifications()->take(4) as $notification)

如果它的关系你可以使用：

@foreach(auth()->user()->unreadNotifications()->take(4)->get() as $notification)

Answer 3

试试这个吧

foreach(\Auth::user()->unreadNotifications->take(1) as $data){echo $data->id;}
