Jquery ajax POST request to Rails (xml) action

Hi we are trying to post data using xml to another rails app.

On the destination app I have this code

class DaemonsController < ApplicationController
skip_before_filter :verify_authenticity_token 
respond_to :xml, :html


def new
 respond_with(@daemon = Daemon.new)
end

def create
 @daemon = Daemon.new(params[:daemon])
 if @daemon.save
   #redirect_to @daemon, :notice => "Successfully created daemon."
   respond_with(@daemon, :location => daemons_url)
 else
   render :action => 'new'
 end
end
end

So XML is allowed for posting data. In my other app I'm using jquery for the data posting

$.ajax({
  type: "POST",
  url: "http://localhost:3000/daemons.xml",
  data: "<daemon><mac>abc</mac><status>1</status></daemon>",

  contentType: 'application/xml; charset=utf-8', // format of request payload
  dataType: 'html', // format of the response
  success: function(msg) {
    alert( "Data Saved: " + msg );
  }
  });

But this returns an error :

Started OPTIONS "/daemons.xml" for 127.0.0.1 at 2011-05-30 12:04:05 +0200

ActionController::RoutingError (No route matches "/daemons.xml"):

When I post the same data using a curl command, everything is working fine

curl -i -X 'POST' -H 'Content-Type: application/xml' http://localhost:3000/daemons -d '<daemon><mac>ABC</mac><status>1</status></daemon>'

<mac-address nil="true"></mac-address>
<status type="integer">1</status>
<updated-at type="datetime">2011-05-30T10:02:39Z</updated-at>

This commes up in the webbrick logs

Does someone know what could be wrong?

Thanks

cURL command is using http://localhost:3000/daemons, while your jQuery is using http://localhost:3000/daemons.xml?

I had this issue with jquery 1.4.x and an older version of rails.js when making a cross site ajax request. I upgraded to jquery 1.6 and the newest rails.js and that seemed to fix it. FWIW, this had to do with setting the CSRF token in the ajax request header. Disabling CSRF protection on the calling side would work as well.
