Replace `.name` with whatever attribute you're using to hold the user's name.

Answer 2

+1 A:

Put something like the following in your controller (assuming the session variable is :user_id):

@username = User.find(session[:user_id]).name

And then in your view use that variable:

Welcome back <%= @username %>

thanx. i tried that. i get undefined method `name' for #<User:0x104212028>how do i know what the session variable is? thanx

@pixelcode: your message means you found a user, but that the User model does not have a method called name. You need to either provide a method called name, or use the existing column name (if it's 'login', use login).
