You could set it like this: @first_name = user.first_name but it is not automatically set, and it is also not typically used like that. A more typical use would be: @user = User.find(params[:id]) and then you can use @user in the controller, but also in the views, due to the set-up of Rails. self.first_name is a method that is dynamically provided by ActiveRecord , based on the available columns for the table "users" in the database.
