Laravel Notification如何设置自定义列值

Question

我使用该php artisan notification:table命令user_id在通知迁移中创建了一个自定义列。如何设置自定义列的值user_id？

Schema::create('notifications', function (Blueprint $table) {

    $table->uuid('id')->primary();

    $table->unsignedBigInteger('user_id');

    $table->string('type');

    $table->morphs('notifiable', 50);

    $table->text('data');

    $table->timestamp('read_at')->nullable();

    $table->timestamps();

    $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade')->onUpdate("cascade");

});

在此功能中，我发送了通知，但引发了错误。user_id列没有默认值

public function saveUser($formdata)

{

    $password = $formdata['password'];

    $securePassword = Hash::make($password);

    $user = User::create(array_merge($formdata, ['password' => $securePassword]));

    $admin = User::where('type', 'admin')->first();

    $letter = collect([

        'title' => $user->name.' New User Registered in your Portal',

    ]);

    Notification::send($admin, new DatabaseNotification($letter));

    return $user;

} 

请帮助我弄清楚如何设置该user_id值。

您应该使用toDatabase或toArray方法来保存任何其他数据。另外，您无需更改通知迁移。您应该$letter在内部构造变量DatabaseNotification，例如：public function saveUser($formdata){    $password = $formdata['password'];    $securePassword = Hash::make($password);    $user = User::create(array_merge($formdata, ['password' => $securePassword]));    $admin = User::where('type', 'admin')->first();    // $letter = collect([    //     'title' => $user->name.' New User Registered in your Portal',    // ]);    // This syntax or below.    // Notification::send($admin, new DatabaseNotification($user, $message));    // Make sure you added `use Notifiable` trait in your `User` model    $admin->notify(new DatabaseNotification($user, $message));    return $user;} 然后在您的toArray或toDatabase方法中：    protected $message;    protected $user;    /**     * Create a new notification instance.     *     * @return void     */    public function __construct($message, User $user)    {        $this->message = $message;        $this->user = $user;    }    /**     * Get the array representation of the notification.     *     * @param  mixed  $notifiable     * @return array     */    public function toArray($notifiable)    {        return [            'user_id' => $this->user->id,            'message' => $this->message        ];    }最终toArray输出序列化到表的data列中notifications。
