在webrick下工作但不在乘客下工作 [英] working under webrick but not under passenger
问题描述
嗨！
我刚刚通过使用Rails进行Agile Web开发的
指令向我的rails应用程序添加了登录功能。但现在我在
乘客/ apache下得到了
奇怪的错误（看起来像某种路由问题）。它在webrick下工作正常。
错误是：
500内部服务器错误
服务器遇到内部错误或配置错误，并且
无法完成您的请求。
来自日志：

有没有人有任何建议我可以做些什么来解决这个问题？

和apache日志：
[错误] [客户端192.168.1.101]由于可能的配置错误，请求超出了10个内部
重定向的限制。如果需要，使用
''LimitInternalRecursion''来增加限制。使用
''LogLevel debug''来获得回溯。
" LogLevel debug"没有提供任何更多信息。
更新：
肯定是路由问题。
我可以通过添加以下内容来部分解决问题：
map.connect''login'',: controller => ''login''，：action => login_page
map.connect''login / list_users'',: controller => " login"，：action => " list_users"
map.connect''login / add_user'',: controller => " login"，：action => add_user
map.connect''login / logout'',: controller => " login"，：action => logout
到routes.rb并且第一行正常工作。
因此重定向到< app> / login或直接输入从登录控制器给出login_page动作。
剩下的问题是我仍然不能直接使用任何动作，如/ login / list_users甚至登录/ login_page。
Hi!
I have just added login feature to my rails application by following the
instructions from "Agile Web Development with Rails" but now I am getting
strange error (looks to me like some kind of routing problem) under the
passenger/apache. It is working fine under webrick.
The error is:
500 Internal Server Error
The server encountered an internal error or misconfiguration and was
unable to complete your request.
From the log:
[4;36;1mSQL (0.3ms)[0m [0;1mSET SQL_AUTO_IS_NULL=0[0m

Does anybody have any suggestion what I could do to fix this?

map.connect '':controller/:action/:id.:format''
end
-------------------------------------------
and apache log:
[error] [client 192.168.1.101] Request exceeded the limit of 10 internal
redirects due to probable configuration error. Use
''LimitInternalRecursion'' to increase the limit if necessary. Use
''LogLevel debug'' to get a backtrace.
"LogLevel debug" didn''t produce any more information.
Update:
It is definitely routing problem.
I could partially solve the problem by adding this:
map.connect ''login'', :controller => ''login'', :action => "login_page"
map.connect ''login/list_users'', :controller => "login", :action => "list_users"
map.connect ''login/add_user'', :controller => "login", :action => "add_user"
map.connect ''login/logout'', :controller => "login", :action => "logout"
to the routes.rb and just first line is working.
So redirecting to the <app>/login or typing it directly gives login_page action from the login controller.
The remaining problem is that I still can''t use any action directly like /login/list_users or even login/login_page.
推荐答案
您是否在登录后检查了会话变量以确保它们准确保存？如果它们不是，它可能会在原始uri和登录之间来回重定向。
Have you checked your session variables after login to make sure they are saving accurately? If they aren''t, it could be redirecting you back and forth between the original uri and login.
感谢您的回复！ :)
你能否更具体地说明我应该检查会话变量的位置。
为什么这个问题不会出现在像
map.connect''login'',: controller => ''login''，：action => login_page
我已经检查过：
map.add_user''add_user'',: controller => " login"，：action => " add_user"
with
<％= link_to''添加用户''，add_user_path％>
这与get一起使用但不是post。
Thanks for the reply! :)
Could you please be more specific about where I should check session variables.
And why doesn''t this problem appear with explicit map.connect routes like
map.connect ''login'', :controller => ''login'', :action => "login_page"
I''ve checked for instance with:
map.add_user ''add_user'', :controller => "login", :action => "add_user"
with
<%= link_to ''Add user'', add_user_path %>
This is working with get but not with post.
我会在login_page中查看。
I would check within login_page.
