Yii2将模型保存到数据库

Question

I'm trying to do simple CRUD application with Yii2, but when I'm trying to save data, no validation errors appears and $model->validate() returns false. Here's my code:

public function actionCreate()
{
    $model = new Game();
    if($model->load(Yii::$app->request->post()) && $model->save())
    {
        $this->redirect(['game-list']);
    }
    return $this->render('create', ['model' => $model]);
}

So, $model->load() returns true and here is my rules() in my model:

public function rules()
{
    return [
        [['title', 'subtitle', 'description'], 'required'],
        [['id_type', 'is_active', 'picture'], 'default'],
    ];
}

I have seven columns in DB (this 6 + id as a primary key). I will be glad if anyone help me.

UPD: View:

<? $form = ActiveForm::begin(array('options' => array('class' => 'form-horizontal'))); ?>
<?= $form->errorSummary($model); ?>
<?= $form->field($model, 'title')->textInput(); ?>
<?= $form->field($model, 'subtitle')->textInput(); ?>
<?= $form->field($model, 'description')->textInput(); ?>
<div class="form-actions">
    <?= Html::submitButton(Yii::t('app', $model->isNewRecord ? 'Create' : 'Update')); ?>
</div>
<? ActiveForm::end(); ?>

My mistake was obviously stupid, but here it is. I've created method beforeSave in my model and haven't filled it and totally forgot about it's existence. So, 'cause it's not returned true - validate() cannot pass properly. Sorry for wasted time.
