更新Symfony 2.4:“仅在处理请求时才可以呈现片段." [英] Updating Symfony 2.4 : "Rendering a fragment can only be done when handling a Request."

问题描述

自从我迁移到Symfony 2.4以来，我收到以下错误消息:

Since I migrated to Symfony 2.4, I'm getting the following error message :

仅在处理请求时才能渲染片段.

Rendering a fragment can only be done when handling a Request.

之所以发生这种情况，是因为在某些页面上，我正在通过$sf2->container->get('twig')->render("MyBundle::my-template.html.twig");在某些页面内用Twig渲染一些模板，这些模板由另一个较旧的框架处理.

It's happening because, on some pages, I'm rendering some templates with Twig inside some pages which are handled by another older framework, by doing $sf2->container->get('twig')->render("MyBundle::my-template.html.twig");.

是的，没错，Symfony 2没有处理那些请求，但是我仍然想用Twig渲染那些模板！为什么我不能(不再)呢?以及如何解决?

So yes, that's right that Symfony 2 isn't handling those requests, but I still want to render those templates with Twig ! Why can't I do that (anymore) ?! And how to fix that ?

这是我正在执行的用于在较早的项目中引导" SF2的代码:

Here is the code I'm executing to "boot" SF2 in my older project :

$loader = require_once __DIR__.'/../../../app/bootstrap.php.cache';
Debug::enable();
require_once __DIR__.'/../../../app/AppKernel.php';

$kernel = new AppKernel('bootstrap', true);
$kernel->loadClassCache();
Request::enableHttpMethodParameterOverride();
$request = Request::createFromGlobals();
$kernel->boot();
$kernel->getContainer()->enterScope('request');
$kernel->getContainer()->set('request', $request, 'request');
$this->container = $kernel->getContainer();

顺便说一句，它可能与此有关:. 但是，我不想降级到Symfony 2.3，并且删除vendor目录并不能解决我的问题.

EDIT : By the way, it might be related to that : Symfony 2.4 Rendering a controller in TWIG throws "Rendering a fragment can only be done when handling a Request." Exception . Though, I don't want to downgrade to Symfony 2.3, and deleting the vendor directory didn't fix my problem.

EDIT²:我发现问题是由于新的

EDIT² : I found out that the problem is because of the new RequestStack.

在HttpKernel中，handleRaw(Request $request, $type = self::MASTER_REQUEST)通常将请求推送到RequestStack($this->requestStack->push($request);).因此，如果我将公共方法pushRequestStack($request)添加到HttpKernel，则它可以工作.我找不到任何能够从HttpKernel获取$requestStack的公共方法(因此我可以从外部推送请求)..

In HttpKernel, handleRaw(Request $request, $type = self::MASTER_REQUEST) normally push the request to the RequestStack ($this->requestStack->push($request);). So if I add a public method pushRequestStack($request) to the HttpKernel it works.. But how could I do it properly ? I don't find any public method able to get the $requestStack from HttpKernel (so I can push the request externally)..

而且我不能使用普通"方法($kernel->handle($request))，因为它会引发一些异常，例如，对于不存在的路由，或者对于已经由PHP启动的会话，都会引发异常.

And I can't use the "normal" method ($kernel->handle($request)) because it would throw some exceptions, for example for the route that doesn't exist, or also for the session that has already been started by PHP..

总而言之，有什么方法可以将我/任何请求推送"到requestStack而不完全处理请求吗?

推荐答案

您必须从Sf2命令的"request_stack"中推送新请求.

You have to push a new Request in the "request_stack" from your Sf2 command.

 $this->getContainer()->get('request_stack')->push(Request::createFromGlobals());
