注:rails的版本是2.0以上.

1.在application.rb里添加分页信息方法:

1 def page_for(result,options={})
2 
3       default_options = {:per_page => 10}   
4        options = default_options.merge options   
5        pages = WillPaginate::Collection.new(options[:page],options[:per_page],result.total_hits)   
6         return pages
7     
8     end

2.users_controller.rb里添加search方法:
3.view页面:

按照网上传统的方法安装几次都没有成功.最后只有下载gem文件安装
1.下载ferret-0.11.6-mswin32.gem文件
2.用gem 安装:gem install ferret-0.11.6-mswin32 --local
3.gem install acts_as_ferret
4.从网上下载ferrect_ext.so文件,copy到 ferret-0.11.5-x86-mswin32\lib目录（跟ferret.rb同一目录）

如果直接下载源码安装运行ruby setup.rb.会出现"the c extensions could not be installed"的错误


手动安装plugins

将下载的源文件放到vendor/plugins里面,进入该目录,运行ruby install.rb

出现的问题:

 解决办法就是把上面安装完成ferret后的文件里找到ferrect_ext.so将这个文件放到lib里面.这个是200多K,而从网上下载的才30K.导致上面的问题.

1.验证码:recaptcha
gem install --source http://www.loonsoft.com/recaptcha/pkg/ recaptcha

2.搜索:acts_as_searchable是一个Rails插件，它依赖于Hyper Estraier这个独立的搜索引擎所提供的索引和搜索服务 
            ferret gem install ferret -v=0.11.5 --platform mswin32  
3.pdf:
gem install pdf-writer  

4.测试:
RSpec+Mocha

5.桌面应用
gem install anvil

使用插件

1/ will_paginate

    http://groups.google.com/group/will_paginate

 

这个资料很多，不多说

 

2/ squirrel

    下载：http://github.com/thoughtbot/squirrel/tree/master

 

主要实现 动态条件的查询，扩展ActiveScaffold find方法。支持跨Model查询，具体见

    说明：http://thoughtbot.com/projects/squirrel

 

贴段主要实现代码

#controller:

def index

#######################################################

#下面代码可以按实际情况提取到Model或其他地方；方便测试我直接放在index下

#######################################################
    @permissions = Permission.find(:all) do
      paginate :page => params[:page]||1,:per_page=>5
      any do
        name == params[:permission][:name] unless params[:permission].nil?
        code == params[:permission][:code] unless params[:permission].nil?
        permit_date == params[:permission][:permit_date] unless params[:permission].nil?
        contact.company == params[:contact][:company] unless params[:contact].nil?
      end
    end
 #######################################################
    respond_to do |format|
      format.html # index.rhtml
      format.xml  { render :xml => @permissions.to_xml }
    end
  end

 

 

#index--view

 

<% field_set_tag do %>
  <% form_for :permission, :url=>permissions_url,:method=>:get,:html=>{:method=>:get} do |f| %>
    公司名称 :<%= text_field_with_auto_complete :contact, :company,{},{:method=>:get}%>  <br>
    证书类型 :<%= text_field_with_auto_complete :permission, :name,{},{:method=>:get}%>  <br>
    证书编号 :<%= text_field_with_auto_complete :permission, :code,{},{:method=>:get}%>  <br>
    授与日期 :<%= text_field_with_auto_complete :permission, :permit_date,{},{:method=>:get}%>  <br>
    <%= submit_tag '查询'  %>
   <% end %>
<%  end %>

 

...

 

<div class="digg_pagination">
  <div clas="page_info">
    <%= page_entries_info @permissions %>
  </div>
  <%= will_paginate @permissions, :container => false %>
</div>
