我试图从SyliusShopBundle覆盖 HomepageController:indexAction
以将一些数据传递给 index.html.twig
但是出现异常:
Catchable致命错误:传递给AppBundle \ Controller \ CustomHomepageController :: __ construct()的参数1必须是Symfony \ Bundle \ FrameworkBundle \ Templating \ EngineInterface的实例,没有给出,在C:\ wamp3 \ www \ acme \ app \中调用缓存\ dev \ appDevDebugProjectContainer.php在1619行并定义
AppBundle/Controller/CustomHomepageController.php:
<?php
namespace AppBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Templating\EngineInterface;
use Symfony\Component\HttpFoundation\Request;
use Sylius\Bundle\ShopBundle\Controller\HomepageController as baseHomepageController;
class CustomHomepageController extends baseHomepageController
{
/**
* @var EngineInterface
*/
private $templatingEngine;
/**
* @return EngineInterface
*/
public function getTemplatingEngine()
{
return $this->templatingEngine;
}
/**
* @param EngineInterface $templatingEngine
*/
public function __construct(EngineInterface $templatingEngine)
{
$this->templatingEngine = $templatingEngine;
}
/**
* @param Request $request
*
* @return Response
*/
public function indexAction(Request $request)
{
//var_dump($request);
$s = "test";
return $this->templatingEngine->renderResponse('SyliusShopBundle:Homepage:index.html.twig',array("data"=>$s));
}
}
AppBundle/Resources/config/services.yml:
services:
app.custom_homepage_controller:
class: AppBundle\Controller\CustomHomepageController
arguments:
- "@templating"
AppBundle/Resources/config/routing.yml:
sylius_shop_homepage:
path: /
defaults:
_controller: app.custom_homepage_controller:indexAction
AppBundle/Resources/views/Homepage/index.html.twig:

<h1>{{ data }}</h1>

{% render(url('sylius_shop_partial_product_index_latest', {'count': 4, 'template': '@SyliusShop/Product/_simpleList.html.twig'})) %}

您需要将模板引擎作为参数传递到服务定义中,这些都是这样的:
