我正在尝试覆盖SyliusShopBundle中的HomepageController:indexAction
以将一些数据传递给index.html.twig
,但会出现异常:
捕获致命错误: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 \中调用第1619行的app \ cache \ dev \ appDevDebugProjectContainer.php并定义了
的appbundle /控制器/ 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));
}
}
的appbundle /资源/配置/ services.yml:
services:
app.custom_homepage_controller:
class: AppBundle\Controller\CustomHomepageController
arguments:
- "@templating"
的appbundle /资源/配置/ routing.yml中:
sylius_shop_homepage:
path: /
defaults:
_controller: app.custom_homepage_controller:indexAction
的appbundle /资源/视图/主页/ index.html.twig:
{% extends '@SyliusShop/layout.html.twig' %}
{% block content %}
<h1>{{ data }}</h1>
<h2 class="ui horizontal section divider header">
{{ 'sylius.ui.latest_products'|trans }}
</h2>
{% render(url('sylius_shop_partial_product_index_latest', {'count': 4, 'template': '@SyliusShop/Product/_simpleList.html.twig'})) %}
{% include '@SyliusShop/Homepage/_promos.html.twig' %}
{% include '@SyliusShop/Homepage/_grid.html.twig' %}
{% endblock %}
答案 0 :(得分:1)
您需要将模板引擎作为参数传递到服务定义中,其中包括:
services:
app.custom_homepage_controller:
class: AppBundle\Controller\CustomHomepageController
arguments:
- "@templating"
