rails auto_complete plugin. how do i pass authenticity token?

Question

I tried the auto_complete text field in rails 2.3.3 and the server says it denied request because of no authenticity token. I can see that the helper doesn't automatically create a parameter for it.

How I can manually do this? And I do not want to disable forgery prevention for this autocomplete.

Honestly, disabling the forgery protection isn't a bad idea if you scope this to just JS.

def index
   respond_to |format| do
     format.html
     format.js do
       # your autocomplete code
     end
   end
end

Make your autocomplete call /things.js instead of /things.

As far as I understand it, forgery protection is not needed for JS responses, and ensuring your autocomplete uses a GET method should also solve your problem. You're displaying a list, you're not modifying state, so use a GET and use the js response.
