aasm_ensure_initial_state() click to toggle source

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
