Posted XML attributes dropped by Rails?

Question

echo '<request><item attribute="foo">bar</item></request>' | curl -X POST -H 'Content-type: application/xml' -d @- http://10.0.1.51:3000/baz/evaluate

My Rails application forgets all about the attribute when it receives the posted XML.

Processing BazController#evaluate (for 10.0.1.3 at 2009-10-03 18:29:32) [POST]
  Parameters: {"request"=>{"item"=>"bar"}}

Any idea what I'm doing wrong?

Answer 1

Hrm... I think this Rails ticket with its associated patch is relevant to this problem.

Given that Hash.from_xml isn't very savvy you could try grabbing the raw XML before Rails messes with it. From the controller, you should be able to do request.raw_post. I think that will get you what you want, though there are other similar method that may be better suited. Once you get the raw XML then you can parse it yourself as necessary.
