Question

我正在使用Laravel Pusher通知，并且能够在创建行时添加通知，但在更新行时遇到困难。这是

下面的代码

CategoryObserver

public function updated(Category $category)
{
    $user = Auth::user();
    foreach($user->followers as $follower)
    {
        $follower->notify(new UpdateCategory($user, $category));
    }
}

和UpdateCategory

class UpdateCategory extends Notification
{
use Queueable;

/**
 * Create a new notification instance.
 *
 * @return void
 */
public function __construct()
{
    //
}


public function via($notifiable)
{
    return ['database'];
}
public function toDatabase($notifiable)
{

    return [
        'following_id' => Auth::user()->id,
        'following_name' => Auth::user()->name,
    ];
}
public function toArray($notifiable)
{
    return [
        'id' => $this->id,
        'read_at' => null,
        'data' => [
            'following_id' => Auth::user()->id,
            'following_name' => Auth::user()->name,
        ],
    ];
}
}

Answer 1

public function updated(Category $category)
{
    $user = Auth::user();
    foreach($user->followers as $follower)
    {
        $follower->notify(new UpdateCategory($user, $category));
    }
}

//在您的通知中

class UpdateCategory extends Notification
{
use Queueable;

public $user;
public $category;

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


public function via($notifiable)
{
    return ['database'];
}
public function toDatabase($notifiable)
{

    return [
        'following_id' => $this->user->id,
        'following_name' => $this->user->name,
    ];
}
public function toArray($notifiable)
{
    return [
        'id' => $this->id,
        'read_at' => null,
        'data' => [
            'following_id' => $this->user->id,
            'following_name' => $this->user->name,
        ],
    ];
}
}

您在无法访问的可排队通知中使用Auth()。从Notification中删除Queueable trait并尝试在Notifications类中注入User对象。

您的构造函数不会使用您传入的参数。相反，您需要在通知中再次请求它们。

$follower->notify(new UpdateCategory( $ user，$ category ));

看起来你不需要这个类别，但你应该像这样使用$ user。

///In your controller
$follower->notify(new UpdateCategory($user, $category));

//In UpdateCategory
public function __construct(User $user, Category $category) //Make sure these are "used" at the top
{
    $this->user = $user;
    $this->category = $category;
}

//Which enables you to use the user *within* the notification later
public function toDatabase($notifiable)
{

    return [
        'following_id' => $this->user->id,
        'following_name' => $this->user->name
    ];
}
public function toArray($notifiable)
{
    return [
        'id' => $this->id, //You also aren't really getting this anywhere? Is it supposed to be the category id?
        'read_at' => null,
        'data' => [
            'following_id' => $this->user->id,
            'following_name' => $this->user->name
        ],
    ];
}

我不确定这是否完全是问题所在，但这绝对是在通知中使用用户的正确方法。

行更新时无法创建通知
