Question

I have a dynamically generated nested namespace like this:

class A
  class B
    class C
      ...
    end
  end
end

I can access class C manually by A::B::C, so it exists, so my generator works. However Object.const_get "A::B::C" raises a “wrong constant name” error. Can I somehow access it dynamically without cumbersome loops?

Answer 1

without loops? not sure.

here is my solution to this, but it does loop through your names:

class A
  class B
    class C
    end
  end
end

c = "A::B::C".split("::").inject(Object) { |n,c| n.const_get c }
p c

A::B::C

here you can see it in action
