You must call super in WacSubProfile#initialize to invoke
WacSubscribers#initialize.

Subject: How to access a attributes from the parent class?
I am new to ruby and try to figure out how inheritance works.
I don't get the result I expect. I marked the line of code with
"#error".
What do I need to do to get it to work?
class WacFrames
attr_reader :wacFrameNav
attr_reader :wacFrameDisp
def initialize()
@wacFrameNav = "nav"
@wacFrameDisp = "disp"
end
end
class WacSubscribers
attr_reader :fr
attr_reader :frame
def initialize()
@fr = WacFrames.new()
@frame = @fr.wacFrameNav
end
end
class WacSubProfile < WacSubscribers
def initialize()
#some code
end
end
end
another = WacSubscribers.new()
puts another.fr #works fine
puts another.frame #works fine
test = WacSubProfile.new()
puts test.fr #error
puts test.frame #error
Thanks
