Yii2 Rbac (DbManager)- 返回 null

Question

Yii::$app->user->can('do_all') return null when i enter by my user (in db only 1 user). What i did wrong.

1)- I created 4 tables.

auth_asignment:  item_name => do_all, user_id => 1
auth_item:       name => do_all, type => 1
auth_item_child: empty
auth_rule:       empty

2)- I added in config/web.php

'components' => [
    'authManager' => [
        'class' => 'yii\rbac\DbManager',
        'defaultRoles' => ['guest'],
    ]
]

3)- In controller i added

public function actionIndex()
{
    if(Yii::$app->user->can('do_all')){
        return $this->render('index');
    }
    else{
        throw new ForbiddenHttpException('The requested page is not exist.');
    }
}

Answer 1

I think you shuld add value in auth_item_child and organize the value this way

try adding a role ind this way

auth_item:        name => do_all_role, type => 1

auth_item_child   parent: do_all_role,  child : do_all

auth_asignment:  item_name => do_all_role, user_id => 1

and use (attention at the class name normally the User class name start with an Uppercase char)

 Yii::$app->User->can('do_all');
