multiple user identity in config Yii2

Question

I developing a site with two different registrations, and I have 2 different table, Im using RbacDB, and in the web config in the components section I have user configuration, a

Answer 1

Try to set a class property in the user-two component:

'user-two' => [
    'class' => 'yii\web\User'
    'identityClass' => 'app\models\SecondUser',
    'enableAutoLogin' => true,
],

or create new class inherited from the yii\web\User class and set like this:

'user-two' => [
    'class' => 'app\models\NewClassInheritedFromUserClass'
    ....
]

Maybe this will help you.

Answer 2

You have to create a web user class for the second identity

namespace app\components;

class UserTwo extends \yii\web\User{
}

than specify the class name in your config

'user-two' => [
        'class'=> 'app\components\UserTwo'
        'identityClass' => 'app\models\SecondUser',
        'enableAutoLogin' => true,
    ],

Answer 3

I have gone through the yii2 framework internals. As I have understood, You can make N Identities following below technique;

---

• Above solutions are just the suggestions which are partial answers and some what helpful. kindly Follow my below changes in depth and you can create N identities as desired.

• N identities are very useful when you do not want to implement Complex RBAC (Role Based Access Control) and just want to Filter Access at controller's request.

• Let us Assume I have to create yet another Identity called 'Franchise' other than existing User which is nicely coupled inside Yii2 Framework.

DB Migrations

1. Create a new migration file using command

   yii migrate/create create_franchise
   

2. Copy paste the content of already available migration file at location PROJECT_NAME\console\migrations something like 'm170311_105858_create_user.php' and rename table name from 'user' to 'franchise'.

3. Now, run migration command

   yii/migrate
   

   • You must get something like this on command prompt

       Apply the above migrations? (yes|no) [no]:yes
     
       applying m170311_105950_create_franchise
       create table {{%franchise}} ... done (time: 1.304s)
       applied m170311_105950_create_franchise (time: 1.350s)
     

4. check DB whether DB is created. (I assume you have made DB settings in PROJECT_NAME\common\config\main-local.php)

5. Please note that whatever may be the Identity class, it shall now use above 'Franchise' Table.

Creating Franchise Model

1. Just goto 'Gii' Module and create a model for newly create franchise table.

2. Model location must be PROJECT_NAME\common\models\Franchise.php

3. Make Sure that the Model class implements IdentityInterface and also implements mandatory methods of IdentityInterface

Identity Class

1. If you go to location PROJECT_NAME\vendor\yiisoft\yii2\web\User.php. This is the class that is referred everywhere in your project as Yii::$app->user. Copy paste the content of this class and create a new File called PROJECT_NAME\vendor\yiisoft\yii2\web\Franchise.php and paste the content in it. Make below changes in the file.

   • Find 'user' and replace it with 'franchise'.
   • Find 'User' and replace it with 'Franchise'.
   • Find $loginUrl = ['site/login']; and replace it with $loginUrl = ['franchise/login']; as you are going to have different controller to handle Franchise related actions.
   • Find $identityCookie = ['name' => '_identity', 'httpOnly' => true]; and replace the 'name' as '_fidentity' (you can see difference, identity cookie must be unique)
   • Find $authTimeoutParam = '__expire'; and replace it with $authTimeoutParam = '_f_expire';

PROJECT_NAME\vendor\yiisoft\yii2\web\Application.php

1. In Application.php add below method,

   public function getFranchise()
   {
       return $this->get('franchise');
   }
   

2. Also find method coreComponents() and add one more entry as below,

   'Franchise' => ['class' => 'yii\web\Franchise'],
   

---

PROJECT_NAME\frontend\config\main.php

1. Inside components add below entry just after 'user' entry,

    'franchise' => [
           'identityClass' => 'common\models\Franchise',
           'enableAutoLogin' => true,
           'class' => 'yii\web\Franchise',
           'identityCookie' => ['name' => '_fidentity-frontend', 'httpOnly' => true],
       ],
