AASM4.1.1 не может работать на Rails4

Question

У меня есть модель, содержащая поле под названием «status». Я изменил его на тип String в DB.And я также использую перечисление в AASM.
вот мой код:

class Card < ActiveRecord::Base 
    include AASM 

    enum status: { 
    default: 0, 
    published: 1, 
    deleted: 2 
    } 

    aasm column: :status, enum: true, skip_validation_on_save: true, no_direct_assignment: true do 
    state :default, initial: true 
    state :published 
    state :deleted 

    event :publish do 
     transitions from: :default, to: :published 
    end 

    event :delete do 
     transitions from: :published, to: :deleted 
    end 
    end 
end 

И я применяю его так:

Card card = Card.first 
card.publish 

Без разницы я называю card.publish или card.delete, я получаю сообщение об ошибке, как это:

Это головоломка меня на несколько дней. Любая помощь будет оценена.

Answer 1

это не должно быть

enum status: [ 
    :default, 
    :published, 
    :deleted 
] 

? Если это не поможет, пожалуйста, откройте open an issue on GitHub, и я более подробно рассмотрю его.
