yii Call to undefined method in authenticate access rules section

Question

We have integrated the yii authenticate acceess rules. In the login page, after submit the form, it displays the following error message shows

Fatal error: Call to undefined method LoginForm::model() in D:\wamp\www\onlinetest\protected\components\UserIdentity.php on line 13

Here is the controller code

public function actionLogin()
    {
        $model=new LoginForm;

        // if it is ajax validation request
        if(isset($_POST['ajax']) && $_POST['ajax']==='login-form')
        {
            echo CActiveForm::validate($model);
            Yii::app()->end();
        }

        // collect user input data
        if(isset($_POST['LoginForm']))
        {
            $model->attributes=$_POST['LoginForm'];
            // validate user input and redirect to the previous page if valid
            if($model->validate() && $model->login())
                $this->redirect(Yii::app()->user->returnUrl);
        }
        // display the login form
        $this->render('login',array('model'=>$model));
    }

Here is the login form model

class LoginForm extends CFormModel
{
    public $username;
    public $password;
    public $rememberMe;

    private $_identity;


       public function tableName()
        {
                return 'tbl_login';
        }



 public function authenticate($attribute,$params)
        {
                if(!$this->hasErrors())  // we only want to authenticate when no input errors
                {
                        $identity=new UserIdentity($this->username,$this->password);
                        $identity->authenticate();
                        switch($identity->errorCode)
                        {
                                case UserIdentity::ERROR_NONE:
                                        Yii::app()->user->login($identity);
                                        break;
                                case UserIdentity::ERROR_USERNAME_INVALID:
                                        $this->addError('username','Username 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;
    }
}

Here is the useridentity.php in components

class UserIdentity extends CUserIdentity
{
   private $_id;
   public function authenticate()
   {
       $record=LoginForm::model()->findByAttributes(array('VarUser_type'=>$this->username));  // here I use Email as user name which comes from database
       if($record===null)
               {
                       $this->_id='user Null';
                                   $this->errorCode=self::ERROR_USERNAME_INVALID;
               }
       else if($record->E_PASSWORD!==$this->password)            // here I compare db password with passwod field
               {        $this->_id=$this->username;
                       $this->errorCode=self::ERROR_PASSWORD_INVALID;
               }


       else
       {  
          $this->_id=$record['VarUser_type'];
           $this->setState('title', $record['VarUser_type']);
           $this->errorCode=self::ERROR_NONE;

       }
       return !$this->errorCode;
   }

   public function getId()       //  override Id
   {

       return $this->_id;
   }
}

you can njot use

 $record=LoginForm::model()->findByAttributes(array('VarUser_type'=>$this->username));

because LoginForm extends CFormModel

for database retrival it should extends CActiveRecord

see this

your model should be like this

class Users extends CActiveRecord
{
/**
 * Returns the static model of the specified AR class.
 * @return Users the static model class
 */

private $_identity;


public static function model($className=__CLASS__)
{
    return parent::model($className);
}

/**
 * @return string the associated database table name
 */
public function tableName()
{
    return 'users';
}

/**
 * @return array validation rules for model attributes.
 */
public function rules()
{
    // NOTE: you should only define rules for those attributes that
    // will receive user inputs.
    return array(

        array(' password, user_name,' , 'required', 'on'=>'login' ),

        array('user_id, last_name, first_name, address1, address2, city, pincode, state_id, country_id, phone, fax, email, created_date, updated_date, last_login, company_name, tour_id, password, user_name, last_login_from, gender, is_session_on, status, memo, cell, role_type_id, group_contract_template_id, group_policy_id, billing_contact, billing_phone, billing_address, billing_email, after_hours_phone', 'safe', 'on'=>'search'),
    );
}

/**
 * @return array relational rules.
 */
public function relations()
{
    // NOTE: you may need to adjust the relation name and the related
    // class name for the relations automatically generated below.
    return array(

    );
}


public function login( $id, $password = "" )
{

    $this->_identity = new UserIdentity($username = $id ,$password);
    $this->_identity->authenticate();
    //Yii::app()->user->login($this->_identity,3600*24*30);

    if(Yii::app()->user->login($this->_identity,0*0*0))
    {
        //echo $this->_identity->errorMessage;
                    return true;
    }
    else
    {
        Yii::app()->user->setState('error', $this->_identity->errorMessage);
        return false;
    }

}


/**
 * @return array customized attribute labels (name=>label)
 */
public function attributeLabels()
{
    return array(
        'user_id' => 'User',
        'last_name' => 'Last Name',
        'first_name' => 'First Name',
        'address1' => 'Address1',

        'email' => 'Email',

    );
}

/**
 * Retrieves a list of models based on the current search/filter conditions.
 * @return CActiveDataProvider the data provider that can return the models based on the search/filter conditions.
 */
public function search()
{
    // Warning: Please modify the following code to remove attributes that
    // should not be searched.

    $criteria=new CDbCriteria;

    $criteria->compare('user_id',$this->user_id,true);
    $criteria->compare('last_name',$this->last_name,true);
    $criteria->compare('first_name',$this->first_name,true);

    $criteria->compare('email',$this->billing_address,true);



    return new CActiveDataProvider($this, array(
        'criteria'=>$criteria,
    ));
}

}

thnx jamin. I am new in Yii. I don't know full function of MVC. I have changed the model from "CFormModel" to "CActiveRecord".I got the followng error Fatal error: Cannot instantiate abstract class CActiveRecord in D:\wamp\www\demo\framework\db\ar\CActiveRecord.php — NitheesBavesh, Aug 02 '14 at 08:28

you don't have included the code for model method

public static function model($className=__CLASS__)
    {
        return parent::model($className);
    }

in your model class

Your UserIdentity class method authenticate is incorrect.. Refer to the code below to see how.

   public function authenticate()
   {
       $record=YourUserModel::model()->find(array(
            'condition'=>'VarUser_type =:username',
            'params'=>array(':username'=>$this->username)
       )); 
       if($record===null)
               {
                       $this->_id='user Null';
                                   $this->errorCode=self::ERROR_USERNAME_INVALID;
               }
       else if($record->E_PASSWORD!==$this->password)            // here I compare db password with passwod field
               {        $this->_id=$this->username;
                       $this->errorCode=self::ERROR_PASSWORD_INVALID;
               }


       else
       {  
          $this->_id=$record['VarUser_type'];
           $this->setState('title', $record['VarUser_type']);
           $this->errorCode=self::ERROR_NONE;

       }
       return !$this->errorCode;
   }
