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'' %>
<h1>Login</h1>
<% if session[:user_id] %>
<%= start_form_tag :action => ''login'' %>
<%= render :partial => ''users/form'' %>
<%= submit_tag "Login" %>
<%= end_form_tag %>
<% else %>
<p>You are logged-in.</p>
<% end %>
<% if session[:user_id] %>
<p>You can logout here.</p>
<%= 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,
Mike

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.
