C:\src\ruby>cd testbbs

config/database.yaml はsqlite3がデフォルトになってた。このままでよし

# SQLite version 3.x
#   gem install sqlite3-ruby (not necessary on OS X Leopard)
development:
  adapter: sqlite3
  database: db/development.sqlite3
  timeout: 5000

# Warning: The database defined as 'test' will be erased and
# re-generated from your development database when you run 'rake'.
# Do not set this db to the same as development or production.
test:
  adapter: sqlite3
  database: db/test.sqlite3
  timeout: 5000

production:
  adapter: sqlite3
  database: db/production.sqlite3
  timeout: 5000

続けてscaffoldでmodel/view/controllerを全部作る。message(投稿者と本文)。

C:\src\ruby\testbbs>ruby script/generate scaffold message name:string body:text
      exists  app/models/
      exists  app/controllers/
      exists  app/helpers/
      create  app/views/messages
      exists  app/views/layouts/
      exists  test/functional/
      exists  test/unit/
      create  app/views/messages/index.html.erb
      create  app/views/messages/show.html.erb
      create  app/views/messages/new.html.erb
      create  app/views/messages/edit.html.erb
      create  app/views/layouts/messages.html.erb
      create  public/stylesheets/scaffold.css
  dependency  model
      exists    app/models/
      exists    test/unit/
      exists    test/fixtures/
      create    app/models/message.rb
      create    test/unit/message_test.rb
      create    test/fixtures/messages.yml
      create    db/migrate
      create    db/migrate/001_create_messages.rb
      create  app/controllers/messages_controller.rb
      create  test/functional/messages_controller_test.rb
      create  app/helpers/messages_helper.rb
       route  map.resources :messages

migrateする（SQLiteのDBを db/migrate/001_create_messages.rb に従って作成する）

rake db:migrate VERSION=001

ちなみに一旦DBを初期化したい時は000。

ではWEBrickで動かしてみる

ruby script/server

http://localhost:3000/messages から見れる
