Yii2 notification widget class not found

问题

I'm trying to use "machour's" notification widget

But somehow I can't even call class: NotificationWidget in my code

It says that "Class is not found"

I'm using yii2-basic-template, how can I call that Class ?

edit:

i tried to create directory: backend/components and tried

use backend/components/Notification;

But i use basic template so i don't think it's right

return $config;

This is the code when i call it:

use backend\components\Notification
<?= NotificationsWidget::widget([
    'theme' => NotificationsWidget::THEME_GROWL,
    'clientOptions' => [
        'location' => 'br',
    ],
    'counters' => [
        '.notifications-header-count',
        '.notifications-icon-count'
    ],
    'listSelector' => '#notifications',
]);

?>

And this is the code inside folder: backend/components:

namespace backend\components;

use Yii;
use common\models\Meeting;
use common\models\Message;
use machour\yii2\notifications\models\Notification as BaseNotification;

class Notification extends BaseNotification

    /**
     * No disk space left !
     */
    const KEY_NO_DISK_SPACE = 'no_disk_space';

    /**
     * @var array Holds all usable notifications
     */
    public static $keys = [
        self::KEY_NEW_MESSAGE,
        self::KEY_MEETING_REMINDER,
        self::KEY_NO_DISK_SPACE,
    ];

    /**
     * @inheritdoc
     */
    public function getTitle()
    {
        switch ($this->key) {
            case self::KEY_MEETING_REMINDER:
                return Yii::t('app', 'Meeting reminder');

            case self::KEY_NEW_MESSAGE:
                return Yii::t('app', 'You got a new message');

            case self::KEY_NO_DISK_SPACE:
                return Yii::t('app', 'No disk space left');
        }
    }

    /**
     * @inheritdoc
     */
    public function getDescription()
    {
        switch ($this->key) {
            case self::KEY_MEETING_REMINDER:
                $meeting = Meeting::findOne($this->key_id);
                return Yii::t('app', 'You are meeting with {customer}', [
                    'customer' => $meeting->customer->name
                ]);

            case self::KEY_NEW_MESSAGE:
                $message = Message::findOne($this->key_id);
                return Yii::t('app', '{customer} sent you a message', [
                    'customer' => $meeting->customer->name
                ]);

            case self::KEY_NO_DISK_SPACE:
                // We don't have a key_id here
                return 'Please buy more space immediately';
        }
    }

    /**
     * @inheritdoc
     */
    public function getRoute()
    {
        switch ($this->key) {
            case self::KEY_MEETING_REMINDER:
                return ['meeting', 'id' => $this->key_id];

            case self::KEY_NEW_MESSAGE:
                return ['message/read', 'id' => $this->key_id];

            case self::KEY_NO_DISK_SPACE:
                return 'https://aws.amazon.com/';
        };
    }

}

Those codes are for Advance template, i think i need to change something to make it works on Basic template

回答1:

Due the fact you are using basic template you should add the configuration elements not in backend/config (this is for advanced template) but in you application directory /config/web.php

eg:

      config = [
        'id' => 'your_app_id',
        'basePath' => dirname(__DIR__),
        'bootstrap' => ['log'],
        'components' => [
             ......
        ],
        // ...
        'modules' => [
            'notifications' => [
                'class' => 'machour\yii2\notifications\NotificationsModule',
                // Point this to your own Notification class
                // See the "Declaring your notifications" section below
                'notificationClass' => 'app\models\Notification',
                // Allow to have notification with same (user_id, key, key_id)
                // Default to FALSE
                'allowDuplicate' => false,
                // This callable should return your logged in user Id
                'userId' => function() {
                    return \Yii::$app->user->id;
                }
            ],
            // your other modules ..
        ],

    ];

and you should change the reference to backend (that is for anvanced template) to you basic directory and namespace in use .. be careful to specify the correct namespace declaration in your extension of this form and its value in use statements

you should move your code in backend/components: in your app\models\

and change the namespace
