Yii2: Cannot perform RBAC migration (You should configure "authManager"...)

Question

As it is described here I'm trying to do the migration in order to let yii create the user authentication tables. However I get the error:

Exception 'yii\base\InvalidConfigException' with message 'You should configure "authManager" component to use database before executing this migration.'

The authManager is present in the configuration but I still get that error. Configuration:

'components' => [
    ...
    'db' => $db,
    'authManager'  => [
        'class'        => 'yii\rbac\DbManager',
        //            'defaultRoles' => ['guest'],
    ],
    ...
],

What's the problem?

Answer 1

Problem was quite simple: The configuration was not used. yii migrate is a console command and usually the configuration for such commands is placed in a seperated file.

In case of yii2-app-base template, from which I have created my application, there is a config/console.php configuration file where the authManager needs to be declared. It is not sufficient to have it in the config/web.php declared only.

In case of yii2-app-advanced the authManager should be declared in console/config/main.php and not in the backend or frontend configuration files.
