Question

I have a simple pair of classes that looks like this:

class X
  include Singleton
  def base_name; self.class.name; end
end

class Y < X
  # ...
end

I would like invocations of #basename on Y (and on any other subclass of X) to return “X”, and not the name of the subclass.

What’s the best way to do that?

Answer 1

Try this:

class A
  BASE_NAME = self.name
  def base_name
    BASE_NAME
  end
end

class B < A
end

A.new.base_name # => "A"
B.new.base_name # => "A"
