→ Including module inside module in Ruby → → →
Basically, the question was (yes, sometimes I have doubts): if you include module A inside module B, and you include module B in class, do you have access to methods defined in module A? Or maybe you have to include module A in the class? The simple answer is that you can include module inside module and both modules will be usable from the class at that point. See below:
module Animal module Mammal def breathe puts 'zzzz....' end end end module Animal module Dog include Animal::Mammal def bark puts 'woof! woof!' end end end class Dingo include Animal::Dog end Dingo.new.bark Dingo.new.breathe
And the output is here:
woof! woof! zzzz....
