Symfony 2.4 在 TWIG 中渲染控制器抛出“渲染片段只能在处理请求时完成".例外 [英] Symfony 2.4 Rendering a controller in TWIG throws "Rendering a fragment can only be done when handling a Request." Exception

问题描述

从 Symfony 2.3 升级到 2.4 后，抛出以下异常:

在第 34 行的 PageBundle::base.html.twig 中渲染模板期间抛出异常(渲染片段只能在处理请求时完成.").

代码正在尝试渲染控制器:

{% 如果不是 app.user %}<div id="login" class="fourcol last">{{ render(controller("SecurityBundle:Front/Security:login")) }}

{％ 万一 ％}

fragmentHandler 抛出异常，因为 $request 为空:

public function render($uri, $renderer = 'inline', array $options = array()){如果 (!isset($options['ignore_errors'])) {$options['ignore_errors'] = !$this->debug;}如果 (!isset($this->renderers[$renderer])) {throw new \InvalidArgumentException(sprintf('%s"渲染器不存在.', $renderer));}如果 (!$request = $this->getRequest()) {throw new \LogicException('渲染片段只能在处理请求时完成.');}var_dump($request);死();return $this->deliver($this->renderers[$renderer]->render($uri, $request, $options));}

这也发生在其他树枝渲染函数调用上.

解决方案

我有同样的错误，但如果我删除vendor"文件夹并通过php composer.phar install"重新启动它，一切正常...

After upgrading from Symfony 2.3 to 2.4, the following exception is being thrown:

An exception has been thrown during the rendering of a template ("Rendering a fragment can only be done when handling a Request.") in PageBundle::base.html.twig at line 34.

The code is trying to render a controller:

{% if not app.user %}
<div id="login" class="fourcol last">
    {{ render(controller("SecurityBundle:Front/Security:login")) }}
</div>
{% endif %}

The exception is being thrown by fragmentHandler because $request is null:

public function render($uri, $renderer = 'inline', array $options = array())
{
    if (!isset($options['ignore_errors'])) {
        $options['ignore_errors'] = !$this->debug;
    }

    if (!isset($this->renderers[$renderer])) {
        throw new \InvalidArgumentException(sprintf('The "%s" renderer does not exist.', $renderer));
    }

    if (!$request = $this->getRequest()) {
        throw new \LogicException('Rendering a fragment can only be done when handling a Request.');
    }
var_dump($request); die();
    return $this->deliver($this->renderers[$renderer]->render($uri, $request, $options));
} 

This is also happening on other twig render function calls.

List of Symfony component versions from composer:

symfony/assetic-bundle               v2.3.0
symfony/icu                          v1.2.0
symfony/monolog-bundle               v2.3.0
symfony/swiftmailer-bundle           v2.3.4
symfony/symfony                      v2.4.0 

Any help would be greatly appreciated

解决方案

i have the same error, but if i delete the "vendor" folder and reinit it via "php composer.phar install", all works fine...
