                    $feed->addChannelTitle(Yii::$app->name);
            },
            'link' => Url::toRoute('/', true),
            'description' => 'Posts ',
            'language' => function ($widget, \Zelenin\Feed $feed) {
                return Yii::$app->language;
            },
            'image'=> function ($widget, \Zelenin\Feed $feed) {
                $feed->addChannelImage('http://example.com/channel.jpg', 'http://example.com', 88, 31, 'Image description');

                },
            'description' => function ($model, $widget, \Zelenin\Feed $feed) {
                    return StringHelper::truncateWords($model->content, 50);
                },
            'link' => function ($model, $widget, \Zelenin\Feed $feed) {
                    return Url::toRoute(['post/view', 'id' => $model->id], true);
                },
            'author' => function ($model, $widget, \Zelenin\Feed $feed) {
                    return $model->user->email . ' (' . $model->user->username . ')';
                },
            'guid' => function ($model, $widget, \Zelenin\Feed $feed) {
                    $date = \DateTime::createFromFormat('Y-m-d H:i:s', $model->updated_at);
                    return Url::toRoute(['post/view', 'id' => $model->id], true) . ' ' . $date->format(DATE_RSS);
                },
            'pubDate' => function ($model, $widget, \Zelenin\Feed $feed) {
                    $date = \DateTime::createFromFormat('Y-m-d H:i:s', $model->updated_at);
                    return $date->format(DATE_RSS);
                }
