将before_filter方法添加到rails 3中列表的末尾

Question

我在application_controller中有before_filter:方法,我希望这个方法在继承类中的before_filter方法之后运行.

我该怎么做？

例

class ApplicationController < ActionController::Base
  protect_from_forgery

  before_filter :run_second
end

class SessionsController < ApplicationController
  before_filter :run_first
end

Answer 1

我认为最友好的Rails方式是prepend_before_filter在SessionsController中使用:

class SessionsController < ApplicationController
  prepend_before_filter :run_first
end
