如何在通知中添加关系?并在json中获取相关数据 [英] How to add relations to notifications? And get the related data in json

问题描述

我正在尝试创建关系，并且当通过$user->unreadNotifications获取通知时，我想控制显示哪些字段并获取关系.我不知道该在哪里做.

I am trying to create relations, and when notifications are fetched via $user->unreadNotifications I want to control which fields are shown, and fetch the relations. I cannot figure out where to do this.

我做了以下事情:

1. php artisan notifications:table
2. php artisan make:migration add_relations_to_notifications_table

3. 在此新迁移中，我添加了requester_id.

1. php artisan notifications:table
2. php artisan make:migration add_relations_to_notifications_table

3. In this new migration I added requester_id.

$table->integer('requester_id')->unsigned()->nullable();
$table->foreign('requester_id')->references('id')->on('users')->onDelete('cascade');

php migrate

然后在AnInviteWasRequested中，我删除了toArray并将其替换为toDatabase:

Then in AnInviteWasRequested I removed the toArray and replaced it with toDatabase:

public function toDatabase($notifiable)
{
    return [
        'requester_id' => Auth::guard('api')->user()->id
    ];
}

但是这并没有设置requester_id字段，它只是将json放入data列中，如下所示:{"requester_id":1}.

However this does not set the requester_id field, it just put json into the data column that looks like this: {"requester_id":1}.

反正有没有办法让它更新requester_id字段而不是更新data?

Is there anyway to get this to update the requester_id field instead of updating data?

在$user->unreadNotifications完成后，是否可以在某个地方(例如模型文件(不在vendor目录中)控制在哪个字段中显示内容?)

And also is it possible somewhere, like a Model file (not in vendor dir) to control which fields are displayed when $user->unreadNotifications is done?

推荐答案

实际上是定义要显示/保存的字段，然后需要显示它，只需修改toDatabase方法即可.示例:

Actually to define which field to show/save, and then you need it to display, you only need to modify the toDatabase method. Example:

public function toDatabase($notifiable)
{
    $user = Auth::guard('api')->user();

    return [
        'requester_id' => $user->id,
        'requester_name' => $user->name,
        // and more data that you need to show
    ];
}

因此对于关系数据或任何其他数据，只需在此方法内定义它.希望能帮助到你. :)

So for relational data or any other data, just define it inside this method. Hope it helps. :)
