这条 Symfony2 路线有什么问题? [英] What's wrong with this Symfony2 route?

问题描述

我已经使用注释设置了一条路线.在我看来是正确的，Symfony2 说这是错误的.路线如下:

I've set up a route using annotations. Looks right to me, Symfony2 says it's wrong. Here's the route:

@Route("/news/{id}/{slug}", name="newsarticle")

这是我认为与路线匹配的示例网址:

Here's a sample URL which I think matches the route:

http://somesite.com/news/202/my-news-title

这里是函数骨架:

public function newsArticleAction($id, $slug)
{

}

我在这里错过了什么?我收到 500 错误，日志显示:

What am I missing here? I get a 500 error and the log says:

推荐答案

这个错误不是在匹配 URL 到路由时出现，而是在从路由生成 URL 时出现.

This error comes up not when matching a URL to a route, but when generating a URL from a route.

在您的项目中搜索 path('newsarticle' 或 generateUrl('newsarticle').您应该会尝试在不传递所有需要的参数的情况下生成 URL — 某事喜欢:

Search your project for path('newsarticle' or generateUrl('newsarticle'. You should find an attempt to generate a URL without passing all the needed parameters — something like:

{{ path('newsarticle', {'slug': news.slug} }}

虽然它必须看起来像:

{{ path('newsarticle', {'id': news.id, 'slug': news.slug} }}
