1. 在你建立的项目 目录下 cmd(dos下命令行下) 建立对象
(cmd下) ruby script/generate scaffold user name:string password:string sex:string
2. 修改models
class User < ActiveRecord::Base
def self.search_by_tag(search, page)
paginate :per_page => 34, :page => page,
:conditions => ['tag like ?', "%#{search}%"],
:order => 'id' (修改排序字段)
end
def self.search(page)
paginate :per_page => 34, :page => page,
:order => 'id' (修改)
end
end
3. 修改 app/controllers 的 users_controller.rb
在 def index 下:
if params[:tag] != nil
@users = User.search_by_tag(params[:tag], params[:page]||1)
else
@users = User.search(params[:page]||1)
end
4. 修改 views/users/index.html.erb
<%= will_paginate @users, :prev_label => '上一页', :next_label => '下一页' %>
好用的!

现在直接 gem install will_paginate 就可以了
别忘了在environment.rb里require一下
