带有通配符和要求的Rails路由 [英] Rails routes with wildcard and requirements

问题描述

我需要设置匹配以下链接的路由：

I need to set up routes wich will match links like this:

1: fixed/9731-monday-tuesday-wednesday-thursday-friday/922-another
2: fixed/potatoe

无限的参数，但是所有参数的格式均为[number]-[some-string]。
第二种情况仅具有一个仅包含角色的参数。

First case has unlimited parameters, however all of them are in format [number]-[some-string]. Second case has only one parameter with caracters only.

我尝试过：

   map.connect("/fixed/*param_list",
               :controller => 'first',
               :action => 'index',
               :requirements => {:param_list => /(\d+-[\w-]+)/})

   map.connect("/fixed/:category",
               :controller => 'second',
               :action => 'index')

但是，具有需求的第一条路线不再像通配符一样起作用。它只匹配ulr，如 / fixed / 922-another ，但不匹配二维或更多维的 / fixed / 922-another / 123-more 。

However first route with requirements doesn't work as with wildcard any more. It only match ulr like /fixed/922-another but not two and more dimensional /fixed/922-another/123-and-more.

所以我的问题是：是否可以通过需求参数化通配符路由？以及如何在我的情况下进行设置。

推荐答案

看来您的正则表达式是错误的。应该不应该是 / \d +-[\w-] +（\ / \d +-[\w-] +）* / 处理多个参数？

It seems like your regexp is wrong. Shouldn't it be /\d+-[\w-]+(\/\d+-[\w-]+)*/ in order to handle multiple parameters?
