Symfony2内部路由在Twig渲染功能 [英] Symfony2 internal route in Twig render function
问题描述
我的 layout.html.twig
:
{{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}
页面
控制器从Doctrine中检索所有页面,并使用一组页面呈现 mainmenu.html.twig
。
The Page
controller retrieves all pages from the Doctrine and renders mainmenu.html.twig
with a set of pages.
我的 mainmenu.html.twig
:
{% if menu_pages is defined %}
{% for page in menu_pages %}
<li class="{% if app.request.attributes.get('_internal') == '_page_show' and app.request.get('id') == page.id %}active{% endif %}"><a href="{{ path('_page_show', {id: page.id}) }}">{{ page.title|e }}</a></li>
{% endfor %}
{% endif %}
但是没有活动
类显示。据了解,问题在于内部路由。如何解决?
But no active
class is displayed. As far as I understand the problem is in internal routing. How to fix that?
推荐答案
更好的不要使用 {{render(controller('AcmeDemoBundle:Page :mainmenu'))}}
。当您使用服务时,它的工作更加快捷舒适。您可以创建一个将在您包含它们的任何页面上显示菜单的服务。在服务中,您可以轻松访问当前 _route
以添加活动
类。
Better do not use {{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}
. It work more fast and comfortable when you use services instead. You can create a service which will show menu on any page where you include them. And in service you can easy get access to current _route
for add active
class.
但是如果你真的需要使用 {{render(controller('AcmeDemoBundle:Page:mainmenu'))}}
,那么你需要传递给他们当前的请求如下:
But if you really need to use {{ render(controller('AcmeDemoBundle:Page:mainmenu')) }}
, so you need pass to them a current request like:
{{ render(controller('AcmeDemoBundle:Page:mainmenu', {'request': app.request})) }}
然后在行动传递请求到twig:
and then in action pass request to twig:
public function mainmenuAction($request) {
return $this->render('AcmeDemoBundle:Page:mainmenu.html.twig', array('request' => $request));
}
在枝条中使用此请求:
{% if menu_pages is defined %}
{% for page in menu_pages %}
<li class="{% if request.get('_route') == '_page_show' and request.get('id') == page.id %}active{% endif %}"><a href="{{ path('_page_show', {id: page.id}) }}">{{ page.title|e }}</a></li>
{% endfor %}
{% endif %}
