laravel中的Database Notifications

创建Post and  User模型

php artisan make:model  Post

php artisan make:model  User

创建posts and  users 表文件

php artisan make:migration create_users_table --create=users

php artisan make:migration create_users_table --create=posts

在表文件设置表结构

Schema::create('posts', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->timestamps();
}); Schema::create('users', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('email');
$table->string('password');
$table->string('remember_token');
$table->timestamps();
});

生成posts and  users and notifications表

php artisan notifications:table

php artisan migrate

创建测试数据

先在database/factories/ModelFactoy.php中设置需要的数据类型

$factory->define(App\User::class, function (Faker\Generator $faker) {
static $password; return [
'name' => $faker->name,
'email' => $faker->unique()->safeEmail,
'password' => $password ?: $password = bcrypt('secret'),
'remember_token' => str_random(10),
];
}); $factory->define(App\Post::class, function (Faker\Generator $faker) {
return [
'name' => $faker->name,
];
});

再执行命令

php artisan  tinker

namespace App

factory('App\User',10)->create()
 
factory('App\Post',10)->create()

创建Notifications目录,以及通知文件

创建之后即可看见InvoicePaid.php  and  UserSubscrible.php 文件

php artisan make:notification   InvoicePaid

php artisan make:notification   UserSubscrible

Formatting Database Notifications

在 notification class 中可以用   toDatabase or toArray  方法 , 将数据存入到数据库中 ,,同时 这两个方法接受$notifiable entity,并返回一个普通的数组(json 格式)。我的代码如下:

//InvoicPaid
public function toArray($notifiable)
{
return [
'post_id' => $this->id,
];
}
/// UserSubscribe
public function toArray($notifiable)
{
return [
'subscribe_at'=>Carbon::now(),// 记录时间
];
}

设置路由

Auth::LoginUsingId(2);
Route::get('/', function () {
// return view('welcome'); Auth::user()->notify(new \App\Notifications\PostPublised());
Auth::user()->notify(new \App\Notifications\UserSubscribed());
});

刷新时即可看见数据库中插入数据了,同时 read_at 字段为 null

Notification 得数据显示

在welcome.php添加如下代码,以驼峰的形式显示数据:

<h2>未读通知</h2>
<ul>
@foreach(Auth::user()->unreadNotifications as $notification)
{{-- @include('notification.'.snake_case(class_basename($notification->type)))--}} <li>{{snake_case(class_basename($notification->type))}}</li>
@endforeach
</ul>
 
<form method="post" action="/user/notification" >
{{csrf_field()}}
<button type="submit">提交</button> </form>

laravel中的Database Notifications

新建  /user/notification 路由, 把未读的通知变为已读的 ,及修改 read_at字段的值  , 第二次刷新页面就不会有数据显示 ,同时可以利用这个对应不同的 用户加载不同的模板

\Illuminate\Support\Facades\Route::post('/user/notification',function (){
\Illuminate\Support\Facades\Auth::user()->unreadNotifications->markAsRead();
});
