In Rails we have request.path_parameters - the Hash of parameters generating a url actually, like :controller, :action, :host, :subdomain, :id or any other due to your routing settings. ex.: http://yoursite.com/articles/1 (:host => ''yoursite.com'', :controller => ''articles'', :action => ''show'', :id => ''1'') request.query_parameters - the Hash of additional parameters, it can be whatever. ex. :http://yoursite.com/articles&q="love" (:q => ''love'') combined accessor ''params'' - the Hash of all parameters. Since it Hash, there is no duplicate keys. Each key is uniq, but the values individual. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you want to get them grouped, just wrap them to array, and your params accessor will be like: {:foo => [''bar'',''bad'',''xyz'']}> > Yeah, I''ve never understood that choice. >Philosophy. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
