laravel：一对多关系insertdata

Question

我创建了一个网络监控工具，可以检查网站的状态，并在网站出现问题时发送通知。如果网站关闭或响应代码与200不同，则计算经过时间，即现在和最后一次检查（或最后一次通知发送）之间的差异。检查频率工作正常。问题在于警报频率。警报频率的elpase时间计算为now和最后一次发送通知之间的时间差，最后一次频率发送的时间戳记在一个名为alerFreqeuncy table的表中。并且有一个通知表，其中包含要检查的网站URL，检查频率和警报频率。通知表和alertFrequency表之间存在一对多的关系。我有两张桌子的模型。

class AlertFrequency extends Model{
    protected $table = 'alertFrequencies';
    public function notification(){
        return $this->belongsTo('App\Notification');}}

和第二个通知模型

public function alertFrequencies(){     
        return $this->hasMany('App\AlertFrequency');}
    public  function alert(){
        $alert_timestamp = AlertFrequency::with('notification')->orderBy('created_at','desc')->select('created_at')->first();
        //$alert_timestamp=$alert_timestamp->created_at->toDateTimeString();
        if($alert_timestamp==null){
            return false;       }       
            return $alert_timestamp;}

现在在我的Guzzle控制器中我想使用通知和alerFrequenct表来计算时间戳，发送通知等，以便动态地将每个网站的记录保存在alertFrequency表中的新时间戳中。这是我的Guzzle cotroller和代码。但它无法奏效。我会给你的帮助吗？
