在ruby状态机中触发状态之间的中间转换

我正在使用

我的代码是

event :set_running do
 transition any => :runnning
end

event :restart do
 transition :failed => :restarting
end

after_transition :failed => :restarting do |job,transition|
  job.set_running
end

after_transition :restarting => :running do |job,transition|
  job.restart_servers 
=begin 
 this takes some time. and i would like job state to be "restarting" while
 it's restarting servers. but it doesn't happen (i suppose because of transaction) 
 until after_transition :failed => :restarting callback is finished.
 so it actually doesnt happen at all because this callback triggers => :running transition
=end
end

换句话说，我想运行一次“重新启动”事件，并在它从：failed传输到：running时触发中介转换。 我可以用状态机来做吗？

现在可以禁用事务：

state_machine :initial => :parked, :use_transactions => false do
