I did try it again and now it throws this error... "Couldn''t find User without an ID" Thank you for your help. -- Posted via http://www.ruby-forum.com/.

Hopefully this will give more info about whats going on.....
This is my login_controller.rb
--------------------------------------------
def login
session[:user_id] = nil
if request.post?
user = User.authenticate(params[:name], params[:password])
if user
session[:user_id] = user.id
redirect_to(session[:original_uri] || { :action => "index" })
else
flash[:notice] = "Invalid user/password combination"
end
end
end
def logout
reset_session
flash[:notice] = "Logged out"
redirect_to(:action => "login" )
end
def index
@all_users = User.find_by_name(params[:name])
end
-----------------------------------------------------
fallowing is my index.rhtml
----------------------------
<%= error_messages_for ''user'' %>
You have logged in !!
<% for user in @all_users %>
<%= user.name %>
<% end %>
---------------------------------------------------------
now in the controller if I do
def index
@all_users = User.find_by_name(:all)
end
it prints all the user names but how could I make it to print the logged
in user name only?
