Database notifications in Laravel

Create a post and user model

PHP artisan make:model  postphp artisanmake: Model  User

Creating Posts and Users table files

PHP artisan make:migration create_users_table--create=usersphp artisanMake: Migration create_users_table-- Create=posts

Set table structure in table file

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 (); });

Generate posts and users and notifications tables

PHP Artisan Notifications:tablephp artisan Migrate

Create test data

Set the required data type in database/factories/modelfactoy.php first

$factory-Define(App\user::class,function(Faker\generator$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,    ];});

Execute the command again.

php artisan  tinkernamespace appfactory (' App\user ', Ten)->create ()

Factory (' App\post ', Ten)->create ()

Create the notifications directory, as well as the notification file

Invoicepaid.php and usersubscrible.php files can be seen after creation

PHP artisan make:notification   invoicepaidphp artisanmake: Notification   usersubscrible

Formatting Database Notifications

In notification class, you can use the toDatabase ortoArray  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 functionToArray ($notifiable)    {        return [            ' post_id ' =$this->id,        ]; }///Usersubscribe Public functionToArray ($notifiable)    {        return [            ' Subscribe_at ' =>carbon::now (),//Recording Time        ]; }

设置路由

Auth::loginusingid (2); Routefunction  () {   //  return view (' Welcome ');     Auth:: User ()->notify (new  \app\notifications\postpublised ());    Auth:: User ()->notify (new \app\notifications\usersubscribed ());});

When you refresh, you see the data inserted in the database, and the Read_at field is null

Notification data show

Add the following code to the welcome.php to display the data in the form of a hump:

        @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" > Submit </button>

</form>

Create a new/user/notification route, change the unread notification to read, and modify the value of the Read_at field, the second refresh page will not have data display, and can use this corresponding different users to load different templates

\illuminate\support\facades\route::p ost ('/user/notification ',function  () {    \illuminate\support\ Facades\auth:: User ()->unreadnotifications->markasread ();});
