使用插件
1/ will_paginate
http://groups.google.com/group/will_paginate
這個(gè)資料很多，不多說(shuō)
2/ squirrel
下載：http://github.com/thoughtbot/squirrel/tree/master
主要實(shí)現(xiàn) 動(dòng)態(tài)條件的查詢，擴(kuò)展ActiveScaffold find方法。支持跨Model查詢，具體見(jiàn)
說(shuō)明：http://thoughtbot.com/projects/squirrel
貼段主要實(shí)現(xiàn)代碼
#controller:
def index

#下面代碼可以按實(shí)際情況提取到Model或其他地方；方便測(cè)試我直接放在index下
