Undefined constant/Scope Missunderstanding

Rails
1

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.

You’re welcome!
