Does Ruby provide the namespace path, e.g. something like [:A,:B] for class A::B::C?

问题

Is the following possible?

puts A::B::C.new.namespace_path # => [:A,:B], or even [A,B]

回答1:

I think maybe #ancestors is what you're looking for.

So A::B::C.ancestors

or you may just want to self.class.to_s.split("::")
