want to separate frontend and backend user in yii2

as there is only user table in yii2 advanced. so user can login to both frontend and backend with same credential . we want saperate it out.

so I created frontuser table ,with same structure as of user table. then created its model using gii model generator

made it as common model/user.

here is frontend/model/frontuser

<?php

namespace frontend\models;

use Yii;
use yii\base\NotSupportedException;
use yii\behaviors\TimestampBehavior;
use yii\db\ActiveRecord;
use yii\web\IdentityInterface;

 * @property string $email
 * @property integer $status
 * @property integer $created_at
 * @property integer $updated_at

but still ,I sign up ,entry goes in user table .. I want to use user table for backend user and frontuser table for frontend user how to do it?

1. Create table in database same field as user table name it frontuser

2. Copy common\models\user.php and place it on frontend\models\frontuser.php make following changes

   • use yii\helpers\Security; • class Frontuser extends ActiveRecord implements IdentityInterface •(return '{{%frontuser}}';)

3. Copy common\models\LoginForm.php in frontend\models\LoginForm.php just change

   namespace frontend\models;

4. frontend\sitecontroller.php • use frontend\models\LoginForm;

5. frontend\models\signup.php just change

   • Replace common to frontend. • new Frontuser
