Tag Cloud Portlet

سلام من بعد از ساختن Tag Cloud Portlet

ه‌ر کاری که میخوام بکنم این ارور میاد


The table "{{tag}}" for active record class "Tag" cannot be found in the database.

components/TagCloudPortlet



کد PHP: 



php?>

Yii::import(’zii.widgets.CPortlet’);

class TagCloud extends CPortlet {

    public $title=’Tags’;

    public $maxTags=20;

protected function renderContent() {

        $tags=Tag::model()->findTagWeights($this->maxTags);

foreach($tags as $tag=>$weight) {

} }

}

تیبل تگ هم اینگونه ساخته شده

    id INTEGER NOT NULL PRIMARY KEY AUTO_INCREMENT,

    name VARCHAR(128) NOT NULL,

    frequency INTEGER DEFAULT 1

خوب توی این هم مشکل خاصی به چشمم نمیاد. بقیه مدلها درست کار میکنن؟ این رو به کامپوننت db اضافه کنید ببینید درست میشه؟

'db'=>array(

    ...

    'tablePrefix' => 'tbl_',

),

بله بقیه مدل‌ها درست کار می‌کنند
حتی خود تگ هم درست کار میکنه، می‌تونم تگ‌های وارد شده در یک پست را نمایش بدم.
کاری که شما گفتین رو کردم بازم درست نشد
