Yii2: The configuration for the "user" component must contain a "class" element.

[githubjeka]

User is configured as an application component in [[\yii\web\Application]] by default.

When I configurated this component inside module then i get error -
The configuration for the "user" component must contain a "class" element.

class RestModule extends Module
{
    public function init()
    {
        parent::init();

        \Yii::configure($this, require(__DIR__ . '/config/main.php'));
    }

//config for Module
return [
    //....
    'components' => [
        'user' => [
            'identityClass' => 'rest\versions\v1\models\User',
            'enableSession' => false,
        ],
    ],
];

Config works fine for application

 'components' => [
        'user' => [
            'identityClass' => 'common\models\User',   
        ],
    ],

the web application has a default setting for a user components class, a module does not have this. You have to specify the 'class' option, which is yii\web\User by default in application.

Ok. Thanks. I thought it inherits from the web application.

It is the other way round, Application inherits from Module.

I suppose you got this error when you were trying to migrate or to do something using the console, it is true that Yii add the class automatically in your component configuration and the user is indeed defined as such, but that only applies for applications based on a web\Application.

I also suppose you are using a custom user configuration and you added it to the config files under the common\ folder. _Correct me if I am wrong!_

Given that common is used by both by the console and the web part of the application, Yii is working correctly but indeed getting an invalid configuration.

Simply moving the user configuration to the config files ones under frontend (or whatever folder contains your web accessible structure) should solve the issue.

Thank you Anini. That was exactly my problem. I putted it in to common config to use it in frontend and backend application.
