AASM4.1.1 can't work on Rails4

Question

I have a model that contain a field called "status".I have change it into String type in DB.And I also use enum in AASM.
here is my code:

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

And I apply it like this:

Card card = Card.first
card.publish

No matter I call card.publish or card.delete,I will get an error like this:

NoMethodError: undefined method `name' for nil:NilClass

It puzzle me for a few days.Any help will be appreciate.

Answer 1

Shouldn't it be

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

? If that doesn't help, please open open an issue on GitHub and I will take a closer look at it.
