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>
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();
});
