Rails session handling on windows problems

I’m doing a simple demo on a windows box, showing how simple it is to
do a user login page, using code from the Agile Programming with Rails
book.

Unfortunately, it’s not acting simple.

This is the view for the login.

<% @page_title = ‘Login’ %>
<%= error_messages_for ‘user’ %>

Login

<% if session[:user_id] %>
<%= start_form_tag :action => ‘login’ %>
<%= render :partial => ‘users/form’ %>
<%= submit_tag “Login” %>
<%= end_form_tag %>
<% else %>

You are logged-in.

<% end %>

<% if session[:user_id] %>

You can logout here.

<%= link_to 'Logout', :action => 'logout' %> <% end %>

Even though both of these sections depend on the :user_id symbol in the
session hash, the first one is working and the second is not.

Also, while logout will run when told, for some reason it stays
logged-in.

Here are the login and logout actions.

def login
if request.get?
session[:user_id] = nil
@user = User.new
else
@user = User.new(params[:user])
begin
logged_in_user = @user.try_to_login
rescue
flash[:notice] = “System error in login attempt!”
render
end
if logged_in_user
session[:user_id] = logged_in_user.id
flash[:notice] = “Logged in as #{logged_in_user.name}!”
redirect_to(:controller => ‘login’, :action => ‘index’)
else
flash[:notice] = “Invalid user/password combination”
end
end
end

def logout
session[:user_id] = nil
flash[:notice] = “You are logged-out”
redirect_to(:action => ‘index’)
end

I’m lost. I’m doing something similar on a linux box and it works fine.

Is this a problem with Rails on Windows?

Thanks,

#First change the view to be

<%= error_messages_for ‘user’ %>

<%= @page_title || 'Login'

<% if @logged_in? -%>
<%= start_form_tag :action => ‘login’ %>
<%= render :partial => ‘users/form’ %>
<%= submit_tag “Login” %>
<%= end_form_tag %>
<% else -%>

You are logged-in.

<% end -%>

<% if @logged_in? -%>

You can logout here.

<%= link_to 'Logout', :action => 'logout' %> <% end -%>

#Then add this to your calling action

@page_title = ‘Login’
@logged_in = (session[:user_id] == nil)

#and no as bad as windows is it is not causing this error
#in future try commenting out and dumping your if conditions

What provides @logged_in? ? That looks like a method call but you’re
referencing it like an instance variable, and it’s nowhere in my code.

I do see that my logic was bad here, but worse, in my controller, if
you visit the login page you are logged-out. This was the core issue.
