要控制调度程序，我将创建一个config/initializers/task_scheduler.rb:

To control the scheduler I would create a config/initializers/task_scheduler.rb:

task_scheduler = Rufus::Scheduler.start_new  

task_scheduler.every("1m") do  
   Something.to_do! # Do something every minute! 
end

现在使用Something.to_do代码，这种类型取决于它的功能.也许它是一个数据模型，应该放在app/models目录中，但是如果它更通用，则可能需要将其放在lib/中.如果您要完成许多计划内的任务，则可能要创建一个app/scheduled_tasks目录，但是对于一个文件来说，这可能会显得有些过分.

Now for the Something.to_do code, that sort of depends on what it does. Perhaps it is a data model and it should go in the app/models directory, but if it is something more generic you might want to place it in lib/. If you wind up with a number of scheduled tasks you might want to create a app/scheduled_tasks directory, but that might be overkill for just one file.
