Rails - Oct 2009 - Undefined constant/Scope Missunderstanding

i got a module x and then a class z and inside this class i do a
Net::HTTP call and it looks for it inside module x ... and i am
clueless...

i get uninitialized constant ModuleX::Net::HTTP

i am new to ruby... and i just dont know how the scope works...
or what i am doing wrong

i took a look at the soap module
and it dosent look like it does anything
different than what i am doing...

this is being called from a file inside lib/

code>
require ''uri''
require ''net/http''

module ModuleX

class Parser
  def self.getData(d)
    htmldata = self.loadData(d)
  end
  private
    def self.loadData(profile)
      url=''''
      htmldata = Net::HTTP.get(URI.parse(url))
      htmldata.to_s
    end
end

end

in advance thanks for shading light

Right.  Since you''re in ModuleX, everything is assumed to be in the 
scope of ModuleX unless fully qualified.  So Parser is ModuleX::Parser 
(which is what you want), and Net::HTTP is ModuleX::Net::HTTP (which you 
don''t want).  To force global scope on Net::HTTP, just qualify it by 
prefixing the scope operator, so you''d write it as
::Net::HTTP.
