Rails skip before action doesn't work
提问by Julien Leray
i've some problem with the skip_before action:
我对 skip_before 操作有一些问题：
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
before_action :require_login
before_action :inc_cookies
def inc_cookies
if cookies[:token] != nil
@name = cookies[:name]
@surname = cookies[:surname]
@user_roomate = cookies[:roomate]
end
end
def require_login
if cookies[:token] == nil
puts "No token"
redirect_to '/'
end
end
end
and my other controller:
和我的另一个控制器：
class UsersController < ApplicationController
skip_before_action :require_login, :except => [:landing, :connect, :create]
end
I don't know why, but when I'm on the root (the :landing action from UsersController), Rails try to pass in the require_login... I've misundertood something with this filter, or do I something wrong?
我不知道为什么，但是当我在 root 上时（来自 UsersController 的 :landing 操作），Rails 尝试传入 require_login ......我误解了这个过滤器的某些内容，还是我有什么问题？
Thanks for any help!
谢谢你的帮助！

This sounds normal to me - you've asked rails to skip your before action, except if the action is :landing, :connector :createwhereas it sounds as though you want the opposite. If you want those 3 actions not to execute the require_loginthen you should be doing
这对我来说听起来很正常 - 你已经要求 rails 跳过你的 before 动作，除非动作是:landing，:connect或者:create听起来好像你想要相反的动作。如果您不希望这 3 个操作不执行，require_login那么您应该这样做
skip_before_action :require_login, :only => [:landing, :connect, :create]
