Yii Crud generates ErrorException out of the box

Question

My problem is similar (or identical ?) to this one. However, the solution offered there does not help me.

I used Gii tot generate a model (Guest) with a search model (GuestQuery). Then I used Gii to generate CRUD for these models. Gii generates the code successfully.

Then, a call to /guest/index results in the following error:

 PHP Warning – yii\base\ErrorException

Invalid argument supplied for foreach()

7. app\controllers\GuestController::actionIndex()

It looks like php get_called_class() returns a string 'app\models\generated\Guest' That would be correct. Next, YiiBase wants to threat this string as an array. Which results in the above error.

How do I get this working?

I am running Yii 2.0.8 on php 7.0.6.

update: the models and controllers are as generated by Gii:

Guest.php

<?php

namespace app\models\generated;

use Yii; 
class Guest extends \yii\db\ActiveRecord
{
/**
 * @inheritdoc
 */
public static function tableName()
{
    return 'guest';
}

/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['created_at', 'remaining_prints'], 'integer'],
        [['cookie_value'], 'string', 'max' => 255],
    ];
}

/**
 * @inheritdoc
 */
public function attributeLabels()
{
    return [
        'id' => Yii::t('app', 'ID'),
        'cookie_value' => Yii::t('app', 'Cookie Value'),
        'created_at' => Yii::t('app', 'Created At'),
        'remaining_prints' => Yii::t('app', 'Remaining Prints'),
    ];
}

/**
 * @inheritdoc
 * @return GuestQuery the active query used by this AR class.
 */
public static function find()
{
    return new GuestQuery(get_called_class());
}

}

GuestQuery.php:

<?php

namespace app\models\generated;

use Yii;
use yii\base\Model;
use yii\data\ActiveDataProvider;
use app\models\generated\Guest;


class GuestQuery extends Guest
{
/**
 * @inheritdoc
 */
public function rules()
{
    return [
        [['id', 'created_at', 'remaining_prints'], 'integer'],
        [['cookie_value'], 'safe'],
    ];
}

/**
 * @inheritdoc
 */
public function scenarios()
{
    // bypass scenarios() implementation in the parent class
    return Model::scenarios();
}

/**
 * Creates data provider instance with search query applied
 *
 * @param array $params
 *
 * @return ActiveDataProvider
 */
public function search($params)
{
    $query = Guest::find();

    // add conditions that should always apply here

    $dataProvider = new ActiveDataProvider([
        'query' => $query,
    ]);

    $this->load($params);

    if (!$this->validate()) {
        // uncomment the following line if you do not want to return any records when validation fails
        // $query->where('0=1');
        return $dataProvider;
    }

    // grid filtering conditions
    $query->andFilterWhere([
        'id' => $this->id,
        'created_at' => $this->created_at,
        'remaining_prints' => $this->remaining_prints,
    ]);

    $query->andFilterWhere(['like', 'cookie_value', $this->cookie_value]);

    return $dataProvider;
}

}

GuestController.php:

/**
 * Lists all Guest models.
 * @return mixed
 */
public function actionIndex()
{
    $searchModel = new GuestQuery();
    $dataProvider = $searchModel->search(Yii::$app->request->queryParams);

    return $this->render('index', [
        'searchModel' => $searchModel,
        'dataProvider' => $dataProvider,
    ]);
}
