- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在尝试在数据更改时向用户发送广播通知。但是每次我尝试发送通知时,都会收到此错误:array_key_exists(): The first argument should be either a string or an integer
.
这是我的通知:
class MyNotification extends Notification
{
use Queueable;
public $games;
public $title;
public $summary;
public $url;
public function __construct($games)
{
$this->games = $games;
$this->title = "Your games";
$this->summary = "Games for {$games[0]->team}";
$this->url = "/some/url";
}
public function via($notifiable)
{
return ['mail','broadcast','database'];
}
/**
* Get the mail representation of the notification.
*
* @param mixed $notifiable
* @return \Illuminate\Notifications\Messages\MailMessage
*/
public function toMail($notifiable)
{
return (new MailMessage)
->subject($this->title)
->line($this->summary);
}
/**
* Get the voice representation of the notification.
*
* @param mixed $notifiable
* @return PushMessage
*/
public function toPush($notifiable)
{
// ...
}
public function toBroadcast($notifiable)
{
return new BroadcastMessage($this->toArray($notifiable));
}
/**
* Get the array representation of the notification.
*
* @param mixed $notifiable
* @return array
*/
public function toArray($notifiable)
{
return [
'icon' => 'fa fa-calendar',
'text' => $this->summary,
'title' => $this->title,
'url' => $this->url
];
}
}
via
中删除“广播”时阵列,一切正常。我不知道我做错了什么!有人可以帮忙吗?谢谢!

$this->games = $games;
, 并编辑
$this->summary
到一些字符串 - 它有效!
$games
是模型
Game
的集合.
最佳答案
如果我理解正确,原因很简单,因为您的模型使用复合键 not supported by eloquent .
所以这就是我认为在我对整个通知/广播模块的了解有限的情况下实际发生的事情。
MyNotification
事件入队Notification
您从中扩展的基类实际上实现了 Illuminate\Queue\SerializesModels
trait 等会自动尝试序列化通知类属性中的所有模型 Game
集合时对象,然后集合尝试调用 getQueueableId
在集合中的每个模型上,然后失败,因为它尝试根据您的复合键 // in Game model
protected $primaryKey = 'id';
broadcastWith
您的
MyNotification
上的方法类,虽然我不确定这是否会绕过
SerializeModels
的序列化方法特征。
// in MyNotification
public function broadcastWith()
{
return ['id' => $this->id];
}
$this->games
使用集合,您可以将其转换为数组。毕竟,最后,你的
toBroadcast
方法是实际控制广播的方法。
$this->games = $games->toArray();
getQueueableId()
你的方法
Game
模型。
// in Game Model
public function getQueueableId()
{
return $this->id;
// or if you still want to utilize your composite keys. UNTESTED
return $this->key_one.$this->key_two;
}
