Class Method Details

.included(base) ⇒ Object

This method:

  • extends the model with ClassMethods

  • includes InstanceMethods

Unless the corresponding methods are already defined, it includes

  • ReadState

  • WriteState

  • WriteStateWithoutPersistence

Adds

before_validation :aasm_ensure_initial_state

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

class Foo
  include MongoMapper::Document
  def aasm_write_state(state)
    "bar"
  end
  include AASM
end

class Foo
  include MongoMapper::Document
  include AASM
  def aasm_write_state(state)
    "bar"
  end
end
