CActiveForm и его поведение не имеют метода или замыкания с именем «getErrors».

Привет я довольно новичок в yii Framework, в настоящее время пытаюсь установить логин через базу данных аутентификации. но я постоянно получаю эту ошибку

CException

CActiveForm и его поведение не имеют метода или замыкания с именем
«getErrors».

кто-нибудь может мне помочь, если это

Вот контроллер

<?php

class SiteController extends Controller

{

public function actions()
{
return array(

'captcha'=>array(
'class'=>'CCaptchaAction',
'backColor'=>0xFFFFFF,
),

'page'=>array(
'class'=>'CViewAction',
),
);
}
public function actionIndex()
{

$this->render('index');
}public function actionError()
{
if($error=Yii::app()->errorHandler->error)
{
if(Yii::app()->request->isAjaxRequest)
echo $error['message'];
else
$this->render('error', $error);
}
}public function actionContact()
{
$model=new ContactForm;
if(isset($_POST['ContactForm']))
{
$model->attributes=$_POST['ContactForm'];
if($model->validate())
{
$name='=?UTF-8?B?'.base64_encode($model->name).'?=';
$subject='=?UTF-8?B?'.base64_encode($model->subject).'?=';
$headers="From: $name <{$model->email}>\r\n".
"Reply-To: {$model->email}\r\n".
"MIME-Version: 1.0\r\n".
"Content-Type: text/plain; charset=UTF-8";

mail(Yii::app()->params['adminEmail'],$subject,$model->body,$headers);
Yii::app()->user->setFlash('contact','Thank you for contacting us. We will respond to you as soon as possible.');
$this->refresh();
}
}
$this->render('contact',array('model'=>$model));
}public function actionLogin()
{
$form=new LoginForm;
if(isset($_POST['LoginForm']))
{
$form->attributes=$_POST['LoginForm'];
if($form->validate()  && $form->login()) $this->redirect(Yii::app()->user->returnUrl);
}

$this->render('login',array('form'=>$form));
}

public function actionLogout()
{
Yii::app()->user->logout();
$this->redirect(Yii::app()->homeUrl);
}

}

вот модель

<?php

class LoginForm extends CFormModel

{
public $email;
public $password;private $_identity;

public function rules()
{
return array(
array('email, password', 'required'),
array('email', 'email'),
array('password', 'authenticate'),
);
}
public function attributeLabels()
{
return array('email'=>'Email Address');
}
public function authenticate($attribute,$params)
{
if(!$this->hasErrors())  // we only want to authenticate when no input errors
{
$identity=new UserIdentity($this->email,$this->password);
$identity->authenticate();
switch($identity->errorCode)
{
case UserIdentity::ERROR_NONE:
Yii::app()->user->login($identity);
break;
case UserIdentity::ERROR_USERNAME_INVALID:
$this->addError('email','Email address is incorrect.');
break;
default: // UserIdentity::ERROR_PASSWORD_INVALID
$this->addError('password','Password is incorrect.');
break;
}
}
}
public function login()
{
if($this->_identity===null)
{
$this->_identity=new UserIdentity($this->username,$this->password);
$this->_identity->authenticate();
}
if($this->_identity->errorCode===UserIdentity::ERROR_NONE)
{
$duration=$this->rememberMe ? 3600*24*30 : 0; // 30 days
Yii::app()->user->login($this->_identity,$duration);
return true;
}
else
return false;
}

}

вот вид

<?php
/* @var $this SiteController */
/* @var $model LoginForm */
/* @var $form CActiveForm  */

$this->pageTitle=Yii::app()->name . ' - Login';
$this->breadcrumbs=array(
'Login',
);
?>
