Laravel 通知以空 user_id 保存在数据库中

Question

当我尝试为用户保存通知时，user_id 列在数据库中始终为 NULL。

我将 Notifiable 特征分配给 User 模型，当我使用 Notification 外观时也会发生这种情况。它只是不在 user_id 列中保存任何内容。

我通过关系获取用户，例如 $this->buyer->user，其中 Buyer 模型属于 User。我可以看到用户已正确检索并具有 ID。

App\Models\User {#1532

        0 => "name"
        1 => "last_name"

    #guarded: array:1 [

    }

我尝试这样发送通知：

$this->buyer->user->notify(new \App\Notifications\MessageReceived(
    $this->message,
    'user 2')
);

MessageReceived.php 文件如下所示

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\BroadcastMessage;
use Illuminate\Notifications\Messages\MailMessage;
use Illuminate\Notifications\Notification;

class MessageReceived extends Notification
{
    use Queueable;

    public $message;
    public $sender;

    /**
     * Create a new notification instance.
     *
     * @return void
     */
    public function __construct($message, $sender)
    {
        $this->message = $message;
        $this->sender = $sender;
    }

    /**
     * Get the notification's delivery channels.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function via($notifiable)
    {
        return [ 'broadcast', 'database' ];
    }

    /**
     * Get the broadcastable representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return BroadcastMessage
     */
    public function toBroadcast($notifiable)
    {
        return new BroadcastMessage([
            'message' => $this->message,
            'sender' => $this->sender,
            'link' =>  '/chat/'
        ]);
    }

    /**
     * Get the type of the notification being broadcast.
     *
     * @return string
     */
    public function broadcastType()
    {
        return 'broadcast.message';
    }

    /**
     * Get the mail representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return \Illuminate\Notifications\Messages\MailMessage
     */
    public function toMail($notifiable)
    {
        return (new MailMessage)->subject('New message received')->view();
    }

    /**
     * Get the array representation of the notification.
     *
     * @param  mixed  $notifiable
     * @return array
     */
    public function toArray($notifiable)
    {
        return [
            'message' => 'You have a new message from ' . $this->sender,
            'link' => $this->business->id . '/chat/' . $this->channel,
            'type' => 'broadcast.message'
        ];
    }
}

当我记录数据库查询时，我得到了这个操作：

  array (
    'query' => 'insert into `notifications` (`id`, `type`, `data`, `read_at`, `notifiable_id`, `notifiable_type`, `updated_at`, `created_at`) values (?, ?, ?, ?, ?, ?, ?, ?)',
    'bindings' => 
    array (
      0 => '960ec22c-f121-4ef7-acca-c0e6105fd760',
      1 => 'App\Notifications\MessageReceived',
      2 => '{"message":"You have a new message from user 2","link":"/chat/","type":"broadcast.message"}',
      3 => NULL,
      4 => 20,
      5 => 'App\Models\User',
      6 => '2021-05-20 19:37:20',
      7 => '2021-05-20 19:37:20',
    ),
    'time' => 148.9,
  ),

我在这个查询中没有看到 user_id 列。这是一个错误还是我做错了什么？我已经遇到这个问题好几个星期了，找不到罪魁祸首。我使用的是 8.12

Answer 1

用户 ID 或通知 ID 存储在 notifiable_id 列。您可以使用 $user->notifications 或 $user->unreadNotifications().

之间的关系获取与用户相关的通知
