ruby-on-rails - ruby rails : How to run things in the background?

Question

当一个新资源被创建并且它需要在资源准备好之前做一些冗长的处理时，我如何将那个处理发送到后台在那里它< em>不会阻止我的网络应用程序的当前请求或其他流量吗？

在我的模型中:

class User < ActiveRecord::Base
 after_save :background_check

 protected
 def background_check
  # check through a list of 10000000000001 mil different
  # databases that takes approx one hour :)
  if( check_for_record_in_www( self.username ) )
    # code that is run after the 1 hour process is finished.
    user.update_attribute( :has_record )
  end
 end
end

您绝对应该查看以下 Railscast:

• http://railscasts.com/episodes/127-rake-in-background
• http://railscasts.com/episodes/128-starling-and-workling
• http://railscasts.com/episodes/129-custom-daemon
• http://railscasts.com/episodes/366-sidekiq

他们解释了如何以各种可能的方式在 Rails 中运行后台进程(有或没有队列......)
