session[:user_id] problem

Hello,

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])       if user.active?

        session[:uid] = user.id         logger.info("session uid = #{session[:uid]}") # it prints out uid successfully       ..............   end end

class ApplicationController < ActionController::Base    before_filter :set_user

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

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

    return true if @user     access_denied     return false   end

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

  ............ end
