session[:user_id] problem


Please help! I ran into a problem that session[:user_id] seems lost.
The session[:user_id] is set during user's login. Other pages have
"before_filter :login_required". The method "login_required" is
defined in ApplicationController to check if session[:user_id] exists.
However, after user logs in successfully (I can see the printed
user_id), and when bringing other pages which call login_required, the
session[:user_id] becomes empty.

I am using rails 1.2.2 and gem version is also 1.2.2.
active_record_store is used for session storage.

Can anyone shed some light on this problem?

Thanks a lot!


Are you sure the value is empty and that it’s just not a display issue on the other pages?
And is the session still in your db?

If those are good can you post some code so we can get a better idea what’s going on?

Thanks Bryan for your help. Yes, I am sure the value is empty, not
display issue. The session is still in db (sessions table). Here is
part of code:

class IndexController < ApplicationController

  def process_student_login
    if user = User.sauthenticate(params[:user])

        session[:uid] ="session uid = #{session[:uid]}") # it prints
out uid successfully

class ApplicationController < ActionController::Base
   before_filter :set_user

def set_user"in set_user: session uid = #{session[:uid]}")
# it prints out nil
    @user = User.find(session[:uid]) if @user.nil? && session[:uid]

  def login_required"in login_required: session uid =
#{session[:uid]}") # it prints out nil

    return true if @user
    return false

class Myaccount::IndexController < ApplicationController
  before_filter :login_required # always fails and returns false
