authentication class wont let me save in the user model

Question

I am trying to save ( $user->save();) the access token to my user table for later use. but for some reason its not saving to my table.

here is my controller

<?php

namespace api\controllers;

use Yii;
use yii\rest\ActiveController;
use yii\filters\auth\CompositeAuth;
use yii\filters\auth\HttpBasicAuth;
use yii\filters\auth\QueryParamAuth;
use common\models\Authentication;

class AuthenticationController extends ActiveController
{
    public $modelClass = 'common\models\Authentication';

    public function actionGrantAuthentication()
    {

        $access_token = null;

        $message = array();

        if (Yii::$app->request->post()) {

            if (!Yii::$app->user->identity || !Yii::$app->user->identity || Yii::$app->user->isGuest) {

                $username = isset(Yii::$app->request->post()['username']) && Yii::$app->request->post()['username'] ? Yii::$app->request->post()['username'] : null;

                $password = isset(Yii::$app->request->post()['password']) && Yii::$app->request->post()['password'] ? Yii::$app->request->post()['password'] : null;

                if ($username && $password) {
                    $user = Authentication::findOne(['username' => $username, 'password_hash' => $password]);

                    if ($user) {
                        //log this user in if the identity is verified
                        Yii::$app->user->login($user);

                        $user->access_token = Yii::$app->security->generateRandomString();

                        $user->auth_key = "djfskdjh";

                        $user->save();

                        $message[] = $user;

                    } else {
                        //add error message
                        $message[] = "Wrong login credentials";
                    }

                } else {
                    $message[] = "Must provide username and password";
                }
            } else {
                $message[] = "you are already logged in";
            }
        }


        return $message;

    }

}

Tipically when a model is not saved in DB this is related to validation problem ..

You can try using for debugging

     $user->save(false);  //this disable the validation rules for user 

Then is the user i saved in db you should looking for the validation rule that fail

you can look at this guide for some suggetion for getting the validation errors

http://www.yiiframework.com/doc-2.0/guide-input-validation.html

if ($user->validate()) {
     // all inputs are valid
     $user->save()
} else {
    // validation failed: $errors is an array containing error messages
     $errors = $model->errors;
     var_dump($errors);
}
