Scaffolds! Help

Rails
1

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

  1. Then I have: rake migrate

  2. 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/…

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’.
