Scaffolds! Help.

Hi im having problems using scaffolds. Im trying to do something very simple, I dont understand the error. Hopefully someone can advise me.

1. I've created my project, set my databases as SQLight and ran the migration: ruby script/generate migration add_a_new_table

2. I have then edited the code in db/migrate/001_add_a_new_table to:

class AddANewTable < ActiveRecord::Migration

  def self.up     create_table :users do |table|       table.column :name, :string       table.column :address, :string       table.column :postcode, :string       table.column :country, :string       table.column :phone, :string       table.column :email, :string

    end   end

  def self.down     drop_table :users   end end

3. Then I have: rake migrate

4. When I run: script/generate scaffold users It seems to work and builds to scaffold. However when i try to view the page: http://localhost:3002/users

It displays this: NameError in UsersController#index

uninitialized constant User RAILS_ROOT: /Users/jim/Documents/work/scaffolds/config/..

This error occured while loading the following files:   user.rb

By default, Rails expects the model to be named the singular version of the table name.

Delete the users.rb model, the users.rb controller, and your users view directory. Then re-run your scaffold with 'user' instead of 'users'.
