Yii2登录 Yii :: $ app-> user-> login（$ user，0）不保存

Question

I am trying implement login at my site. But seems like Yii::$app->user->login($user, 0) doesn't save identity.

When I've just logged in it work fine:

    if (Yii::$app->user->login($user, 0) ) {
        var_dump(Yii::$app->user->identity);
    } else {
        echo 'didnt login';
    }

var_dump() show identity.

But when I am trying obtain identity in another controller var_dump() shows NULL:

// In other controller
var_dump(Yii::$app->user->identity);

Does somebody know about this problem?

Okay. Guy in russian yii forum answered the question. (http://yiiframework.ru/forum/viewtopic.php?f=19&t=19135&start=20)

namespace app\models;

use yii\db\ActiveRecord;
use yii\web\IdentityInterface;

class User extends ActiveRecord implements IdentityInterface
{}

I should implement IdentityInterface and I've forgotten. Now it works well!
