I am new with PHP and trying to create yii App and I have to use yii1.1

I am following https://www.yiiframework.com/doc/guide/1.1/en/quickstart.first-app

I generated Gii and after I got to the last step which is "Accessing CRUD Pages", I faced this error:

Unable to resolve the request "user"

I checked the User file and its name.
While the database is succesfully connected.

And here is the code of User file where its directory is : testdrive1/protected/models/User.php

<?php

/**

 * This is the model class for table "tbl_user".

 *

 * The followings are the available columns in table 'tbl_user':

 * @property integer $id

 * @property string $username

 * @property string $password

 * @property string $email

 * @property string $image

 * @property double $lat

 * @property double $lng

 */

class User extends CActiveRecord

{

    /**

     * @return string the associated database table name

     */

    public function tableName()

    {

        return 'tbl_user';

    }



    /**

     * @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('username, password, email', 'required'),

            array('lat, lng', 'numerical'),

            array('username, password, email', 'length', 'max'=>128),

            array('image', 'length', 'max'=>100),

            // The following rule is used by search().

            // @todo Please remove those attributes that should not be searched.

            array('id, username, password, email, image, lat, lng', '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(

        );

    }



    /**

     * @return array customized attribute labels (name=>label)

     */

    public function attributeLabels()

    {

        );

    }
