Hi
I have a file in /lib/test_class.rb whic looks like this
module TestClass
class TestClass
def mehtod1
end
def more methods ....
end
end
in one of my controllers I have
require ''test_class''
This seems to work, however when I do the next line to create an object
it fails
test = TestClass.new
Any ideas where I am going wrong?

Uh, you have to specify the module name... test = TestClass::TestClass.new Ruby may be smart, but it''s not prescient.

Remember that when you say: TestClass.new you are actually calling the "new" method on the module, not the class. To actually get the class you have to dig into it with the "::" operator. TestClass::TestClass.new However, if you simply want to inlcude the class in your app you dont need to wrap it in a module at all. And then you dont need the :: at all. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
