Rails routes with wildcard and requirements

问题

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

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

I'v tried this:

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

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

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.

So my question is: Is possible to parametrized wildcard route via requirments? And how to set up it in my case.

回答1:

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