在Laravel发生注销事件时发布时间戳数据

Question

发生登录事件时，以下代码为Login Event Listener。

我也做了Logout Event Listener作为与登录一样的设计。

它的工作原理，但它只是在同一个表中的另一行。

那么我怎样才能将Logout数据写入表中登录数据的同一行呢？ 是否可以将数据发布到登录数据保存行的deleted_at？

谢谢:)

LogSuccessfulLogin.php

<?php 

namespace App\Listeners; 

use Illuminate\Auth\Events\Login; 
use Illuminate\Http\Request; 

use App\LoginHistory; 

class LogSuccessfulLogin 
{ 
    /** 
    * Create the event listener. 
    * 
    * @param Request $request 
    * @return void 
    */ 
    public function __construct(Request $request) 
    { 
     $this->request = $request; 
    } 

    /** 
    * Handle the event. 
    * 
    * @param Login $event 
    * @return void 
    */ 

    public function handle(Login $event) 
    { 

     LoginHistory::create([ 
      'user_name' => $event->user->name, 
      'last_login_at' => date('Y-m-d H:i:s'), 
      'last_login_ip' => $this->request->ip(), 
     ]); 

     $user = $event->user; 
     $user->last_login_at = date('Y-m-d H:i:s'); 
     $user->last_login_ip = $this->request->ip(); 
     $user->save(); 
    } 
} 

LogSuccessfulLogout.php

<?php 

namespace App\Listeners; 

use Illuminate\Auth\Events\Logout; 
use Illuminate\Http\Request; 

use App\LogoutHistory; 
use App\LoginHistory; 
use \Carbon\Carbon; 
use DateTime; 

class LogSuccessfulLogout 
{ 
    /** 
    * Create the event listener. 
    * 
    * @param Request $request 
    * @return void 
    */ 
    public function __construct(Request $request) 
    { 
     $this->request = $request; 
    } 

    /** 
    * Handle the event. 
    * 
    * @param Login $event 
    * @return void 
    */ 
    public function handle(Logout $event) 
    { 
    $log = LoginHistory::where('user_name', $event->user->name)->first(); 

     if($log) 
     { 
      //logout timestamp store. 
      $log->last_logout_at = date('Y-m-d H:i:s'); 
      $log->save(); 

      //calculate time_worked 
      $strStart = Carbon::now(); 
      $strEnd = $log->last_login_at;  
      $dteStart = new DateTime($strStart); 
      $dteEnd = new DateTime($strEnd);  
      $dteDiff = $dteStart->diff($dteEnd); 
      // print $dteDiff->format("%H:%I:%S"); 
      // dd($dteDiff); 
      $log->time_worked = $dteDiff->format("%H:%I:%S"); 
      $log->save(); 
     } 
    } 
} 

Answer 1

在这种情况下，它很简单找到用户ID LogoutHistory然后更新它：

public function handle(Logout $event) 
{ 
    $log = LogoutHistory::where('user_name', $event->user->name) 
        ->latest('last_login_at') 
        ->first(); 

    if($log) { 
     $log->last_logout_at = date('Y-m-d H:i:s'); 
     $log->save(); 
    } 
} 

PS：假设user_name是在user表

Answer 2

可以使用soft delete添加deleted_at列中的唯一。

然后你就可以查询这样

$log = LogoutHistory::where('user_name', $event->user->name)->delete(); 

这将在deleted_at列中添加时间戳。
