How to install twig on yii2?

Question

Yii

I did everything as described www.yiiframework.com/doc-2.0/guide-tutorial-templa...
I put yii2-app-basic
in web.php

'view' => [
            'class' => 'yii\web\View',
            'renderers' => [
                'twig' => [
                    'class' => 'yii\twig\ViewRenderer',
                    'cachePath' => '@runtime/Twig/cache',
                    //'options' => [], /*  Array of twig options */
                    'globals' => ['html' => 'yii\helpers\Html'],
                    'uses' => ['yii\bootstrap'],
                ],
            ],
        ],

created layout template - layout_main.twig (views/layouts/layout_main.twig)
created view - index.twig (views/site/index.twig)
in controller

public function actionIndex(){
        return $this->render('index.twig');
}

gives the error The view file does not exist: .....\views\layouts\main.php
What could be the problem?

Answer 1

Maybe you need to rename the main template to main.php?

Answer 2

It is necessary to disable the default layout of the application

$config = [
  'layout' => false,
]

or only for the controller

class BaseController extends Controller
{
    public $layout = false;
}

Answer 3

right, it will not work, because you did not specify through which layout to process your view.
It is necessary to specify a new layout in the controller, for example:

class SiteController extends Controller
{
    public $layout = 'layout_main.twig';
