URL encode & decode

I have a link:
<%= link_to ‘delete’, :action => ‘destroy’, :id => u(string_id) %>

Helper method ‘u()’ can encode a string to URL encoding, but I don’t
know which method can decode it? I want to used in controller. I have
not seen it in Rails’s document.

Thanks,

---------------------------------------------------------- CGI::unescape
CGI::unescape(string)

  URL-decode a string.

    string = CGI::unescape("%27Stop%21%27+said+Fred")
       # => "'Stop!' said Fred"

(you will need

require ‘cgi’

in your controller)
