How do I add autoincrement?

Hello,

     I am attempting to learn Ruby on Rails. I'm using Instant Rails 2.0 on a Windows computer. I really want the id number to autoincrement, but I am not sure how to do that. The script that's generated after the scaffold is listed below. Any help is appreciated.

class CreateMenuitems < ActiveRecord::Migration   def self.up     create_table :menuitems do |t|       t.integer :id       t.string :category       t.text :categoryinfo       t.string :name       t.string :price       t.text :iteminfo

      t.timestamps     end   end     insert into menuitems values(NULL);   def self.down     drop_table :menuitems   end end

Remove this line. Rails will add the id field for you.
