:除非不能在应用程序控制器的before_filter中工作。路由问题? [英] :except not working in before_filter in application controller. Routing problem?
问题描述
我的应用程序控制器中有一个before_filter,可以使用户会话保持活动状态(如果超时,则将其注销)。应该在除/ sessions / new和/ sessions / destroy以外的所有操作(分别以/ login和/ logout路由)上调用此操作。
I have a before_filter in my application controller to keep a user's session alive (and log them out if a time out has been reached). This should be called on every action except /sessions/new and /sessions/destroy which are routed as /login and /logout.
我的应用程序控制器的相关部分看起来像这样;
The relevant parts of my application controller look like this;
class ApplicationController < ActionController::Base
before_filter :update_activity_time, :except => [:login, :logout]
private
def update_activity_time
if current_user
time_out = current_user.setting.remember_me ? 20160 : current_user.setting.user_timeout
from_now = time_out.minutes.from_now
end
if session[:expires_at].blank?
session[:expires_at] = from_now
else
time_left = (session[:expires_at].utc - Time.now.utc).to_i
if time_left <= 0
session_expiry
else
session[:expires_at] = from_now
end
end
end
def session_expiry
reset_session
flash[:notice] = 'Your session has expired. Please log back in.'
unless request.xhr?
session[:return_to] = request.request_uri
redirect_to login_url
else
session[:return_to] = request.referer
render :js => "window.location.replace(\"#{login_url}\")"
end
end
end
和我的route.rb包含以下内容;
and my routes.rb contains the following;
map.login "login", :controller => "sessions", :action => "new"
map.logout "logout", :controller => "sessions", :action => "destroy"
在访问/ login或/ logout时将调用before_filter。这不是停止显示,但确实会引起一些奇怪的行为(例如,从已超时的页面注销时)。
The before_filter is being called when /login or /logout are being visited. This isn't a show-stopper but it does cause a few odd behaviours (e.g. when logging out from a page that has timed out).
任何主意我是什么我做错了吗?我正在使用Rails 2.3.10。
Any ideas what I'm doing wrong? I'm using Rails 2.3.10.
推荐答案
:except
选项采用动作名称,而不是网址部分。相反,您应该执行以下操作:
The :except
option takes action names, not url parts. Here's what you should do instead:
class ApplicationController < ActionController::Base
before_filter :update_activity_time
...
end
然后,在 sessions_controller.rb
中:
class SessionsController < ApplicationController
skip_before_filter :update_activity_time, :only => [:new, :destroy]
...
end
不想将:except
放在 ApplicationController
中,因为如果这样做,则 new每个应用程序控制器的
和 destroy
操作都不会更新活动时间。
You don't want to put the :except
in ApplicationController
because, if you did, the new
and destroy
actions for every one of your app's controllers wouldn't update the activity time.
