Hi,

session[:id] holds the current user''s id, although you have to set it
manually when the user logs in to your site, e.g session[:id] @user.id

Hope that helps.

To be a bit more clear, you can use whatever you want in the session,  
it doesn''t have to be :id.  It can be :user_id, :logged_in_user_id,  
whatever.  But Patrick is correct in that the value has to get set  
when the user is logged in.  If you''re using something like  
acts_as_authenticated, it handles all of that for you and you can use

current_user.id

But if you''re rolling your own like I do, then you set the session  
variable when the user successfully authenticates. Something like:

# find user by email and password
user = User.find_by_email_and_password(params[:email], params 
[:password])
if user
	session[:user_id] = user.id
	redirect_to :controller => ''user'', :action =>
''home''
else
	flash[:error] = "Invalid login!"
	redirect_to :action => ''login''
end

Peace,
Phillip
