ruby on rails - XML-based RESTful API

Question

I've created a basic RESTful service with rails g scaffold and it fails to accept XML request sent by ActiveResource (works fine with JSON POST requests and XML GET requests). It fails with ActionController::ParameterMissing so obviously it has something to do with whitelisting but I can't figure out what exactly I should send. Any suggestions?

Answer 1

It seems that XML support was removed in Rails 4 so actionpack-xml_parser gem is required to deal with XML requests.
