I'm trying to refactor a superfat model which has quite a few lines of ActsAsStateMachine code related to the states and transitions, and I was hoping to refactor this to a module call CallStates.
#in lib/CallStates.rb
module CallStates
module ClassMethods
aasm_column :status
aasm_state :state1
aasm_state :state2
aasm_state :state3
end
def self.included(base)
base.send(:include, AASM)
base.extend(ClassMethods)
end
end
And then in the model
include CallStates
My question concerns how to include Module behavior into a Module such that a single Module can be included into the model. I've tried class_eval do as well to no avail. Thanks for any insightful thoughts you have on the matter.

You can't include one module in another exactly, but you can tell a module to include other modules in the class into which it's included:
It's best to only do this if Bmodule is actually data that is necessary for Amodule to function, otherwise it can lead to confusion because it's not explicitly included in MyClass.
