Artisan command notification to all users gives BadMethodCallException

Question

How can I create an artisan command to send a database notification to all users in the system containing information of how long they have been in the system for?

My SendEmails Command looks like the following:

    <?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use App\User;
use Illuminate\Support\Facades\Mail;
use App\Mail\UserEmails;
use Illuminate\Support\Facades\Notification;

class SendEmails extends Command
{
    /**
     * The name and signature of the console command.
     *
     * @var string
     */
    protected $signature = 'send:emails';

    /**
     * The console command description.
     *
     * @var string
     */
    protected $description = 'Send Email to allusers';

    /**
     * Create a new command instance.
     *
     * @return void
     */
    public function __construct()
    {
        parent::__construct();
    }

    /**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $users = User::all();
        foreach($users as $user){
            $created_at = $user->created_at;
            Notification::send($user, new SendEmailsNotification($created_at));
        }
    }
}

Then I created the notifications table, migrated and the code is the below:

<?php

namespace App\Notifications;

use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;

class SendEmailsNotification extends Notification
{
    use Queueable;

    public $created_at;

    public function __construct($created_at)
    {
        $this->created_at = $created_at;
    }

    public function via($notifiable)
    {
        return ['database'];
    }

    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->line('The introduction to the notification.')
                    ->action('Notification Action', url('/'))
                    ->line('Thank you for using our application!');
    }

    public function toArray($notifiable)
    {
        return [
        ];
    }
}

User.php:

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
//use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    //use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password', 'address', 'image'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        //'email_verified_at' => 'datetime',
        'address' => 'array'
    ];

    protected $uploads = '/images/';

    public function getImageAttribute($image){
        return $this->uploads . $image;
    }

    public function contacts(){
        return $this->hasMany('App\Contact');
    }
}

When I run the artisan command "php artisan send:emails" I see the following error in the console:

BadMethodCallException : Call to undefined method App\User::routeNotificationFor()

How can I send the notification to all users?

Answer 1

You just need to uncomment the // use Notifiable line.

The Notifiable trait includes two other traits, one of which is the RoutesNotifications trait.

The RoutesNotifications trait is what you need to be able to send Notifications to a User.

Also, you should be able to simplify your code in your SendEmails command to be:

Notification::send(User::all(), new SendEmailsNotification()); 

And instead of explicitly passing created_at you can just access it from $notifiable in your SendEmailsNotification (as in this case $notifiable will be the User model anyway) e.g.

public function toArray($notifiable)
{
    return [
        'data' => 'Account Created' . $notifiable->created_at->diffForHumans()
    ];
}

}
