Rails - Feb 2007 - format a string in params

Hi,
i''ve got a problem with slashes "/" :
i do a redirect :

redirect_to :action => action, :id => params[:my_param]

but when parameter string params[:my_param] is with slash, for example
"16/9", i''ve got the following error

no route found to match "/controller/action/16/9" with
{:method=>:get}

does anybody know a function to format that kind of parameter to get a
valid url?

Hi, what does 16/9 represent?  In any case, you''ll need to sanitize,
params[:my_param], before you redirect.

Good luck,

Thank you for your answer.

I''ve found a solution : encode parameter.
put in the controller header  :
require ''cgi''
before send encode parameter :
CGI::escape(params[:my_param])
at reception decode it :
CGI::unescape(params[:my_param])

Then, i keep valid url :)

You don''t need to use the CGI escape, Rails gives you the same thing,
it is called h (alias for html_escape) that does the same thing.

URL encoding is NOT the same thing as HTML escaping. I don''t see h() in
the api docs, but I''m pretty sure it would leave "/" alone
since it
doesn''t need to be escaped in HTML.

No, html_escape as the same means translate html.
To translate url we have to use url_encode :
http://www.ruby-doc.org/stdlib/libdoc/erb/rdoc/classes/ERB/Util.html

but i didn''t find the way to decode it....

Ah, the u() method, a counterpart to h().

Rails decodes URLs automatically. However, if for some reason you
needed to do this yourself:

def url_decode(str)
     str.to_s.gsub(/%([A-F\d]{2})/in) { [$1.hex].pack(''C'') }
end

- Mark.
