Rails: How to escape ampersand in URL formation -

-

i have link_to helper following:

<%= link_to "example & text", url_for(:controller =>'example', :title=>"example & text") %>

it frames url http://localhost:3000/example?title=example&amp:text

in sample controller calls index method params[:title] returns value example&amp:text.

i want have value "example & text". have tried cgi::escape() , cgi::escapehtml() without luck.

the url needs escaped using cgi.escape:

link_to "example & text", :controller => "example", :title => cgi.escape("example & text")

this should generate like:

<a href="/example?title=example+%26+text">example & text</a>

then, wherever you're wanting use this, can unescape again normal:

cgi.unescape params[:title] # => "example & text"
