I’m attempting to create a RESTful Web service using 1.2.2. I would  
like to be able to update a model via an XML payload PUT to the  
controller, but the scaffold\_resource PUT handler  
(MyController#update) seems to only work with values of the form  
“modelname[columname]=value”. If I supply anything else – such as the  
same XML that the scaffolded GET returns – it gets ignored by the  
controller.

I’m guessing that I need to roll my own #update, which is fine. How  
can I get my hands on the raw data sent over by the PUT invocation? Or  
is there a better way of accomplishing this?

Thanks!

I figured it out by poking through the ActiveController::Base source.

To make this work, you have to specify “Content-type: application/xml”  
in the HTTP PUT request. This triggers logic set up by default in the  
ActionController::Base.param\_parsers hash to parse the XML and put it  
in the params hash for the REST controller to use.
