How can I switch from one subpattern to another in different modules?

Question

Yii

Good afternoon,
I want to have several subtemplates in the created admin module. Created so far 4 - Default column1 and column2 and duplicated them column1-admin and column2-admin

class AdminModule extends CWebModule
{
  public function init()
  {
        $this->layout =  '/layouts/main';
  }
}

class DefaultController extends Controller
{
  public function actionIndex()
  {
        $this->layout = '//layouts/column1';
    $this->render('index');
  }

    public function actionView()
    {
        $this->layout = '//layouts/column2';
        $this->render('index');
    }
}

column1.php

<?php $this->beginContent('//layouts/main'); ?>
<div id="content">
    column1
  <?php echo $content; ?>
</div><!-- content -->
<?php $this->endContent(); ?>

column2.php

<?php $this->beginContent('//layouts/main'); ?>
<div class="span-19">
  <div id="content">
        column2
    <?php echo $content; ?>
  </div><!-- content -->
</div>
<div class="span-5 last">

  <div id="sidebar">

  <?php
    $this->beginWidget('zii.widgets.CPortlet', array(
      'title'=>'Operations',
    ));
    $this->widget('zii.widgets.CMenu', array(
      'items'=>$this->menu,
      'htmlOptions'=>array('class'=>'operations'),
    ));
    $this->endWidget();
  ?>
  </div><!-- sidebar -->
</div>
<?php $this->endContent(); ?>

In my default controller, none of the action outputs the word: column1 or column2.
I tried to write in the init of the module like here vispyanskiy.name/ru/kak-zadat-shablon-dlya-modulya... :

$this->layoutPath = Yii::getPathOfAlias('admin.views.layouts');
$this->layout = 'main';

Then I tried to set the path from the DefaultController actions :

$this->layout = 'admin.views.layouts.main.column1';

I fly into the text with my content, but without styles, i.e. The topic is not included.
On the advice of this Chinese https://www.youtube.com/watch?v=Nc0ED8_VsT4 :
Commented out in protected/components/Controller.php :
// public $layout = '//layouts/column1';
But it didn't help.
I can easily connect to this view:
admin.views.layouts.main
But it's not so interesting, I want to take subtemplates as well.
Help me please.
