As a result, it doesn't matter when you define your methods - the following 2 are equivalent

before_validation :aasm_ensure_initial_state

Adds

* includes InstanceMethods
* extends the model with ClassMethods

This method:

def self.included(base)
  base.send(:include, AASM::Persistence::Base)
  base.send(:include, AASM::Persistence::ORM)
  base.send(:include, AASM::Persistence::MongoidPersistence::InstanceMethods)
  base.extend AASM::Persistence::MongoidPersistence::ClassMethods
  base.after_initialize :aasm_ensure_initial_state
end
