使用Symfony2在Twig Extension中包含资产 [英] Include assets in Twig Extension with Symfony2

问题描述

我想在Twig扩展名中包含资产和一些脚本文件.例如.我想声明树枝函数{{ init_project() }}，但是当我在树枝函数'<script type="text/javascript" src="{{ asset('bundles/mybundle/js/script.js') }}"></script>'中编写代码时，它不起作用，它在浏览器的调试面板中返回404错误.那我该怎么做呢?

I want to include asset with some script file in Twig extension. E.g. I want to declare twig function {{ init_project() }}, but when I writing in my twig function '<script type="text/javascript" src="{{ asset('bundles/mybundle/js/script.js') }}"></script>', it dont work, it return 404 error in debug panel of browser. So how I can do this?

推荐答案

查看'asset'树枝函数:

Look at the 'asset' twig function :

您可以在\Symfony\Bundle\TwigBundle\Extensions\AssetsExtension

public function getAssetUrl($path, $packageName = null, $absolute = false, $version = null)
    {
        $url = $this->container->get('templating.helper.assets')->getUrl($path, $packageName, $version);

        if (!$absolute) {
            return $url;
        }

        return $this->ensureUrlIsAbsolute($url);
    }

而不是在扩展名中调用'{{asset}}'，只需调用公共功能getAssetUrl()

Instead of calling '{{asset}}' in your extension, just call the public function getAssetUrl()
