Question

我有一个名为通知的模型。该模型负责从数据库中获取数据。它有一个静态方法，可以将从数据库中检索到的数据更改为字符串值。如果存储的数据是200，则将其更改为“up”，否则将其更改为“down”。我在我的刀片页面中调用了此功能，以根据其状态显示所有网址。也就是说，它会显示“向上”，“向下”和“未激活”的网址。由于某种原因，它无法显示网站，对于关闭和没有活跃的网站，它做得很好。

这是我的模型：通知模型

<?php

namespace App;
use App\Status;
use App\Notification;

use Illuminate\Database\Eloquent\Model;

class Notification extends Model
{
    protected $fillable = ['id','website_url','email','slack_channel','check_frequency','alert_frequency','speed_frequency','active'];

    public function statuses(){
        return $this->belongsToMany('App\Status')->withPivot('values')->withTimestamps();
    }

    public function status($s_type)
    {
        if (!in_array($s_type, ['speed', 'health'])){
            return false;
        }

        $o_status = Status::where('name', strval($s_type))->first();
        $o_response = $this->statuses()->where('status_id', $o_status->id)
        ->select('values', 'created_at')->orderBy('created_at','DESC')->first();

        if($o_response === null){
            return false;
        }

        return [
            'value' => $o_response->values,
            'timestamp' => $o_response->created_at
        ];
    }

    public function history($s_type)
    {
        if (!in_array($s_type, ['speed', 'health'])){
            return false;
        }

        $o_status = Status::where('name', strval($s_type))->first();
        $o_response = $this->statuses()->where('status_id', $o_status->id)
        ->select('values', 'created_at')->orderBy('created_at','DESC')->get();

        if($o_response === null || $o_response->count() === 0){
            return false;
        }


        $a_ret = [];
        $last = null;

        foreach ($o_response as $o_status) {
            if($last != $o_status->values) {
                $a_ret[] = [
                'value' => $o_status->values,
                'timestamp' => $o_status->created_at
                ];
                $last = $o_status->values;
            }
        }
        return $a_ret;
    }

    public static function health($resCode)
    {
        return intval($resCode) === 200 ? 'up' : 'down';
    }
}

这是我的刀片页面

 <tbody>
        @foreach($notes as $notification)
            <?php $notificationHealth = $notification->status('health'); ?>
            <?php $notificationSpeed = $notification->status('speed'); ?>
            @if ((is_null($active) || $notification->active == $active) && (empty($health) || ($health === 'down' && empty($notificationHealth['value'])) || $notificationHealth['value'] === $health))

                <tr> 
                    <td> {{ $notification->website_url }} </td>

                   @if($notificationHealth !== false)
                        @if(\App\Notification::health($notificationHealth['value']) == 'up')
                            <td> {{ \App\Notification::health($notificationHealth['value']) }} <span class="up"></span><br><span class="timestamp_green">{{  $notificationHealth['timestamp'] }}</span></td>.

                        @elseif(\App\Notification::health($notificationHealth['value']) == 'down')
                            <td> {{ \App\Notification::health($notificationHealth['value']) }}  <span class="down"></span><br><span class="timestamp_red">{{ $notificationHealth['timestamp'] }}</span></td>

                        @else
                            <td> {{ \App\Notification::health($notificationHealth['value']) }}  <span class="unsigned"></span><br><span class="timestamp_unsigned">{{ $notificationHealth['timestamp'] }}</span></td>

                        @endif
                    @else
                        <td> N/A <span class="unsigned"></span></td>       
                    @endif
