问题描述

在我的route.rb中尝试重写的规则可能是不言自明的:

This attempted rewrite rule in my routes.rb is probably self-explanatory:

match "/:user/:photo-thumb.png" =>
      redirect("/%{user}/photos/%{photo}/image?style=thumb"),
      :photo => /[a-zA-Z]+/

我想重定向诸如mysite.com/alice之类的内容/foo-thumb.png到mysite.com/alice/photos/foo/image?style=thumb

I want to redirect something like mysite.com/alice/foo-thumb.png to mysite.com/alice/photos/foo/image?style=thumb

上述尝试不过是错误的。有任何解决方案吗?

The above attempt is wrong though. Any ideas for fixing it?

推荐答案

以下方法对我有用:

match "/:user/:photo_thumb.png" =>
      redirect{|p|
        "/#{p[:user]}/photos/#{p[:photo_thumb].split('-')[0]}/image?style=thumb"
      },
      :constraints => { :photo_thumb => /[a-zA-Z]*\-thumb/ }

我很想找到一种更简单的方法。 (正如塔德曼指出的那样,我最好通过nginx重写来做到这一点。请参阅以下相关问题:)

I'd love to find a simpler way to do it though. (As tadman points out, I may be better off doing this with nginx rewrites. See this related question: Routes.rb vs rack-rewrite vs nginx/apache rewrite rules )
