How to solve Call to undefined method Illuminate\\

问题:

My function create in controller is like this :

public function create()
{ 
    // This is dummpy data to testing checkout order event
    $data = array(
                'number'            => '2', 
                'user'              => 'chelsea',
                'store'             => 'chelsea shop', 
                'total_amount'      => 11000000, 
                'total_product'     => 2,
                'status'            => '92000000', 
                'delivery_address'  => 'london',
                'email'             => '[e-mail]'
            );
    $data = Order::where('number', $data['number'])->first();
    \Event::fire(new CheckoutOrderEvent($data));
}

My CheckoutOrderListener is like this :

<?php
namespace App\Listeners;
use App\Events\CheckoutOrderEvent;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
class CheckoutOrderListener
{
    public function __construct()
    {
        //
    }

    public function handle(CheckoutOrderEvent $event)
    {
        $event->data->notify(New \App\Notifications\CheckoutOrder());
    }
}

I had add use Illuminate\Notifications\Notifiable; in model order

But, when executed, there exist error : Call to undefined method Illuminate\Database\Query\Builder::notify()

Is there anyone can help me?

Update

The full error is like this :

My CheckoutOrderEvent is like this :

<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class CheckoutOrderEvent
{
    use InteractsWithSockets, SerializesModels;
    public $data;

    public function __construct($data)
    {
        $this->data = $data;
    }
    public function broadcastOn()
    {
        return new PrivateChannel('channel-name');
    }
}

My CheckoutOrder is like this :

<?php
namespace App\Notifications;
use Illuminate\Bus\Queueable;
use Illuminate\Notifications\Notification;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Notifications\Messages\MailMessage;
class CheckoutOrder extends Notification
{
    use Queueable;
    public function __construct()
    {
        //
    }
    public function via($notifiable)
    {
        return ['mail'];
    }
    public function toMail($notifiable)
    {
        return (new MailMessage)
                    ->line('The introduction to the notification.')
                    ->action('Notification Action', 'https://laravel.com')
                    ->line('Thank you for using our application!');
    }
    public function toArray($notifiable)
    {
        return [
            //
        ];
    }
}

My model order is like this :

use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Notifications\Notifiable;

class Order extends Model
{
    use SoftDeletes;
..........

回答1:

As from the discussion I found out that you did not include the Notifiable trait in your Order model. Do this instead:

use Eloquent as Model;
use Illuminate\Database\Eloquent\SoftDeletes;
use Illuminate\Notifications\Notifiable;

class Order extends Model
{
    use SoftDeletes, Notifiable;
    ..........

By including it, your model should now have the notify method as it should, and so can be used in the Notification system.

I also got this error while put a query like

$data = DB::abcd("Select * from xyz"); ,(abcd->filename)

but we need to put

$data = DB::select("Select * from xyz");
