ruby-on-rails-4 - 一个模型中的多个状态机，用于带有 aasm 的枚举字段

Question

我正在使用 Rail 4.2.3 和 aasm gem 4.1 版是否可以在一个模型中为枚举字段添加两个状态机？

我有枚举状态：[:active, :suspended, :deleted] 和枚举活动：[:working, :stopped]

我不会像这样的2个状态机：

aasm(:connection_state, column: :state, enum: true do
    state :active, initial: true
    state :suspended
    state :deleted

    event :activate do
      transitions from: :suspended, to: :active
      transitions from: :deleted, to: :active
    end

    event :suspend do
      transitions from: :active, to: :suspended
    end

    event :mark_as_deleted do
      transitions from: [:active, :suspended], to: :deleted
    end
  end

和其他状态机：

aasm(:activity_state, column: :activity, enum: true do
    state :working, initial: true
    state :stopped

    event :start_working do
      transitions from: :stopped, to: :working
    end

    event :stop_working do
      transitions from: :working, to: :stopped
    end
  end

但规格因错误而失败：

expect(subject).to transition_from(:active).to(:suspended).on_event(:suspend)

AASM::UnknownStateMachineError：在 ModelName 中没有定义名称为“默认”的状态机

我错过了什么？

Answer 1

我的规范中有问题，只是没有仔细阅读文档：

expect(subject).to transition_from(:active).to(:suspended).on_event(:suspend).on(:connection_state)
