Ensures that if the aasm_state column is nil and the record is new that the initial state gets populated before validation on create
foo = Foo.new foo.aasm_state # => nil foo.valid? foo.aasm_state # => "open" (where :open is the initial state) foo = Foo.find(:first) foo.aasm_state # => 1 foo.aasm_state = nil foo.valid? foo.aasm_state # => nil
