Rule not found: isfieldofficer found in yii2

I have Groupdetails CRUD application.

In auth_item table, I created two roles namely



In auth_assignment, I assigned admin to Employee having id 29 and fieldofficer to Employee having id 13 and 28

In auth_rule, I added rule isfieldofficer

Now in models folder I create foll rule


namespace app\models;

use Yii;

use yii\rbac\Rule;

use app\models\Groupdetails;


 * Checks if authorID matches user passed via params


class FieldofficerRule extends Rule


    public $name = 'isfieldofficer';


     * @param string|int $user the user ID.

     * @param Item $item the role or permission that this rule is associated with

     * @param array $params parameters passed to ManagerInterface::checkAccess().

     * @return bool a value indicating whether the rule permits the role or permission it is associated with.


    public function execute($user, $item, $params)


        return isset($params['groupdetails']) ? $params['groupdetails']->EmpId == $user : false;




Now in actionView()

I have foll

public function actionView($id)


        $model = $this->findModel($id);



            return $this->render('view', [

            'model' => $this->findModel($id),





           throw new ForbiddenHttpException("You can't view other created groups details");



Now when I view, I got foll error:

Invalid Configuration – yii\base\InvalidConfigException
