aasm_write_state(state, name=:default)

Writes state
to the state column and persists it to the database using update_attribute (which bypasses validation)
foo = Foo.find(1) foo.aasm.current_state # => :opened foo.close! foo.aasm.current_state # => :closed Foo.find(1).aasm.current_state # => :closed

Private Instance Methods
aasm_ensure_initial_state()

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
