How to fix Class 'App\Http\Controllers\Notification' not found in laravel?

Question

I have a Controller which listens to a new Schedule creation and sends the result back to the view via ajax. Inside of it I want to add a Notification to send email to the user once the Schedule cannot be completed due to a lack of resources at that specific date and time.

The problem is that I get the error below:

Class 'App\Http\Controllers\Notification' not found in /laravel/app/Http/Controllers/DadosAgendamentoController.php on line 89

The folder structure is this:

-app -Http -Controllers DadosAgendamentoController.php -Notifications AgendamentoPendente.php

DadosAgendamentoController.php head code:

namespace App\Http\Controllers; use Input; use Request; use App\Servicos; use App\Disponibilidades; use App\Estabelecimentos; use App\HorariosEstabelecimento; use App\Agendamento; use App\User; use App\Notifications\AgendamentoPendente;

line 88 and 89:

$user = User::where('id',1)->get(); Notification::send($user, new AgendamentoPendente(1));

Trough my Controller I can access all the classes above, but not the AgendamentoPendente

My goal is to send an email do the admin so he can suggest a new date and time to the client when the resources are not available at the desired date and time.

How can it be fixed? Can I access the class in this Controller? How?

Please show us 89th line of DadosAgendamentoController.php — Alexey Mezenin

I almost sure you haven't imported Notification class. Just import the namespace and it should be fixed. If Notification is a facade, just invoke by \Notification::foo() — felipsmartins

@felipsmartins, I've seen that User has a default config for using the Notifications and I've tried to use also the command use Illuminate\Notifications\Notifiable;, no success, though — Jaqueline Passos

@JaquelinePassos The Alexey Mezenin's answer is right. Even though it is not solve your question, theres a issue in another place/scope. — felipsmartins

Notifications may be sent in two ways: using the notify method of the Notifiable trait or using the Notification facade.

https://laravel.com/docs/5.3/notifications#sending-notifications

Option 1

You can use notify() method:

$user->notify(new AgendamentoPendente(1));

Also, make sure User class uses Notifiable trait:

use Illuminate\Notifications\Notifiable; class User extends Authenticatable { use Notifiable;

Option 2

Using facade with full namespace:

\Notification::send($user, new AgendamentoPendente(1));

The error is solved but It didn't worked as expected... Laravel Notifications are sent only if a new data of a model is created on the database? Is this how it works? Can I send it only if a table field value is set to false?

Add use Notification; in your controller

OR

alternatively, use \Notification::send($user, new AgendamentoPendente(1));

add this at the top of the controller:

use App\Notifications\AgendamentoPendente;

i was having the same problem and this fixed it

Also note that if you are using the facade, make sure your User queries the email field from your database

$users = User::select("email")->get(); \Notification::send($users, new AgendamentoPendente(1));

You have to use facades at the top

use Illuminate\Support\Facades\Notification;

You can refer to this tutorial

You can pull in the notification library used Lumen 8.0:

"illuminate/notifications": "5.3.*" into your composer.json then running composer update to pull in the notification libraries.

You will also need to add

$app->register(Illuminate\Notifications NotificationServiceProvider::class);

to your bootstrap/app.php

This process working for me. Thanks
