ActiveResource NameError: wrong constant name with complex xml tag

[cdangelo]

Hi all,
I'm using ActiveResource to communicate with a "custom" REST application.
My model use the ":from" to customize the url and it receives an xml response.
find(:one, :from => "/XXX/service/Decreto/"+id.to_s+"/caricaDocumento")
The server is a java application that serialize objects using XStream. In the xml I have some tag names with full class name (for example it.mypackage.MyClass).
When ActiveResource parse the xml to create attributes the system go in error with

NameError: wrong constant name it.mypackage.MyClass
from /home/ruby/.rvm/gems/ruby-1.9.3-p194/gems/activeresource-3.2.6/lib/active_resource/base.rb:1428:in const_defined

The problem in find_or_create_resource_for is caused by const_defined? with a parameter that contains "it.mypackage.MyClass" (with dot)

It can be resolved changing the line
resourcename = name.to_s.camelize
with
resource_name = name.to_s.gsub(/\W+/, '').camelize

or better using an external method that can be overrided

Same here.. really annoying

here is a quick hack found on airbrake support page:

class ActiveResource::Base
  alias_method :old_find_or_create_resource_for, :find_or_create_resource_for  unless self.respond_to?(:old_find_or_create_resource_for) 

  def find_or_create_resource_for(name)
    name = name.to_s.gsub(".","_").camelcase.to_sym
    old_find_or_create_resource_for(name)
  end  
end

Is it planned to be fixed soon or we should monkeypatch to deal with it?
