ruby – AASM：将状态机定义与类定义分开

class Job < ActiveRecord::Base
  include AASM

  aasm do
    state :sleeping,:initial => true
    state :running
    state :cleaning

    event :run do
      transitions :from => :sleeping,:to => :running
    end

    event :clean do
      transitions :from => :running,:to => :cleaning
    end

    event :sleep do
      transitions :from => [:running,:cleaning],:to => :sleeping
    end
  end

end

我不喜欢我的状态机定义与我的类定义混合的事实(因为当然在实际项目中我会向Job类添加更多方法).

我想在模块中分离状态机定义,以便Job类可以是以下内容：

class Job < ActiveRecord::Base
  include StateMachines::JobStateMachine
end

然后我在app / models / state_machines中创建了一个job_state_machine.rb文件,其内容类似于：

module StateMachines::JobStateMachine
  include AASM

  aasm do
    state :sleeping,:to => :sleeping
    end
  end

end

但这不起作用,因为AASM被包含在不在Job类中的模块中……我甚至尝试将模块更改为：

module StateMachines::JobStateMachine
  def self.included(base)
  include AASM

  aasm do
    state :sleeping,:to => :sleeping
    end
  end
  end
end

但它仍然没有工作……任何提示或建议都非常感激.

谢谢,

编辑：

感谢Alto,正确的解决方案是：

module StateMachine::JobStateMachine

  def self.included(base)
    base.send(:include,AASM)

    base.send(:aasm,column: 'status') do
    ....
    end
  end
end

并且显然要记得在主类中包含状态机定义,如下所示：

include StateMachine::JobStateMachine
