应用程序控制器中的before_filter仅用于获取请求

Question

我需要在我的ApplicationController中设置一个before_filter,如果用户尚未同意新的服务条款,则会重定向用户.但是,我想将过滤器限制为仅根据请求类型运行.

我想写这样的东西:

class ApplicationController

before_filter :filter, :only => {:method => :get}

这样的事情可能吗？

Answer 1

before_filter :do_if_get

private

  def do_if_get
    return unless request.get?

    # your GET only stuff here.
  end

或者更简单

before_filter :get_filter, if: Proc.new {|c| request.get? }

private

  def get_filter
    # your GET only stuff here.
  end
