Rails 更新至 2.0.2相關

Rails 2.0 的鷹架已經改為外掛：
如果直接使用動態鷹架，則會出現： undefined method `scaffold' for .... 的錯誤訊息

ruby script\plugin install scaffolding
(來源： http://dev.rubyonrails.com/svn/rails/plugins/scaffolding/ )

還要安裝 pagination(分頁)的套件 (否則會出現 undefined method `pagination' for...)
ruby script/plugin install svn://errtheblog.com/svn/plugins/classic_pagination
(若無法安裝，則使用：
ruby script/plugin install http://tools.assembla.com/svn/breakout/breakout/vendor/plugins/classic_pagination/
或
ruby script/plugin install svn://errtheblog.com/svn/plugins/will_paginate
)
