�?rails的版本是2.0以上.

1.在application.rb里添加分��信息方�?

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�Ҏ(gu��)��:

1   def search
2
3     @keyWord=params[:keyWord]
4     if params[:page]==nil||params[:page]==""
5       @page=1
6     else
7       @page=params[:page]
8     end
9     @users=User.find_by_contents(@keyWord,:per_page=>2,:page=>@page)
10     @pages=page_for(@users,:page=>@page,:per_page=>2)
11   end

3.view��面:

1 <%@users.each do |user|%>
2 
3 username: <%=user.highlight(@keyWord,:field=>:user_name,:num_excerpts=>1,:pre_tag=>'',:post_tag=>'')%> 
4 地址:<%=user.highlight(@keyWord,:field=>:introduce,:num_excerpts=>1,:pre_tag=>'',:post_tag=>'')%>
5 ==================================================================================
6 <%end%>
7 
8 �?/span><%=@users.total_hits%>条记�?br /> 9 p>
10 
11 <%=link_to "上一��?/span>",{:page=>@pages.previous_page,:keyWord=>@keyWord} %>
12 <%=link_to "下一��?/span>",{:page=>@pages.next_page,:keyWord=>@keyWord} %>

安装f(xi��)erret

bobqiu — Fri, 20 Feb 2009 14:31:00 GMT

按照�|�上传统的方法安装几�ơ都没有成功.最后只有下载gem文�g安装
1.下蝲ferret-0.11.6-mswin32.gem文�g
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�g,copy�?ferret-0.11.5-x86-mswin32\lib目录�Q�跟ferret.rb同一目录�Q?br />
如果直接下蝲源码安装�q�行ruby setup.rb.�?x��)出�?the c extensions could not be installed"的错�?br />

手动安装plugins

ror执行��程

bobqiu — Mon, 05 Jan 2009 08:18:00 GMT

    1.we receive a new request for a page to our rails application.
    2.Rails routes this request to a controller for processing.
    3.Our controller interacts with the models in our application to gather the necessary data
    4.Our model may retrive or insert data to our database
    5.Once our models have generated or retrived correct information,they return the data back to the collection
    6.The controller collects all of the data it's received from models and selects a view template to render
    7.The view template is rendered using the data that the collection gathered and handed to the web server
    8.An html page is returned to the user.

Rails Routing from the Outside In

bobqiu — Fri, 19 Dec 2008 06:12:00 GMT

Rails Routing from the Outside In
http://guides.rails.info/routing_outside_in.html
�q�篇文章��介�l�Rails routing针对用户斚w��的一些特�?参考这��文�?你将�?x��)学��C��下知�?
a.理解routing的作�?br /> b.破解routes.rb内的代码
c.构徏你自��q��routes,可以用classic hash样式或现在流行的RESTful样式.
d.识别route怎样与controller和action映射.

1.The Dual Purpose of Routing

Rails routing 有两�U�机�?你可以将trees转换为pager,或把paper转换回trees.具体地说,它可以连接收到的��h��与你应用�E�序的控制器的代码和帮你生成URLs,而不用做��Z��个字�W�串��编�?

1.1connecting URLs to Code;
当你的应用程序收到的��h��?
GET /patients/17
Rails里的路由引擎��是一�D�分发这个请求到应用�E�序合适的位置�q�行处理的一�D�代�?在这个案例中,�q�个应用�E�序很可能以�q�行patients控制器里的show�l�束.昄��patients ID�?7的详�l�信�?

1.2 Generateing URLs from Code
Routing 也可以反�q�来�q�行,如果你的应用�E�序中包含这��L(f��ng)��代码:

@patient=Patient.find(17)
<%= link_to "Patient Record",patient_path(@patient)%>

�q�时路由引擎转换�q�个链接��C��个URL:http://example.com/patients/17.以这�U�方式你可以降低应用�E�序的脆弱�?使你的代码更加容易阅��d��理解.

Patient 必须作�ؓ(f��)一个resource被声明�ؓ(f��)一个资�?通过named route来�{�?

2.Quick Tour of Routes.rb

在Rails中routing有两�U�组�?routing engine本��n,它做为Rails的一部分,config/routes.rb文�g,它包含实际的可用在应用程序中的routes.

2.1 Processing the File
在�Ş式上,Routes.rb文�g也就是一个大大的block,�?x��)被攑օ�ActionController::Routing::Routes.draw.
在这个文件中有五�U�主要的样式:
RESTful Routes
Named Routes
Nested Routes
Regular Routes
Default Routes

2.2 RESTful Routes
RESTful Routes 利用rails嵌入式REST�Ҏ(gu��)��来将routing的所有信息包装�ؓ(f��)一个单独的声明.eg: map.resource :books

2.3 named Routes
named routes 在你的代码中�l�你很可�ȝ��链接,也可以处理收到的��h��

map.login '/login' ,:controller=>'session',:action=>'new'

2.4 Nested routes

Nested routes可以在一个资源里声明另一个资�?

map.resources :assemblies do |assemblies|
assemblies.resources :parts
end

2.5 Regular Routes
map.connect 'parts/:number',:controller=>'inventory',:action=>'show'

2.6 Default Routes
map.connect ':controller/:action/:id'
map.connect ':controller/:action/:id.:format'

Routes

bobqiu — Tue, 16 Dec 2008 01:58:00 GMT

routes:

routes的命名允�怽�减少重复的代�?通过分配一个根据生成一个封装routes rule hash的方法的路径规则名称来实�?
你可以定义一个命名�\�?你可以调用它在你的routes.rb文�g中来代替connect�Ҏ(gu��)��.
例如:
map.home '',:controller=>'main',:action=>'start'
�q�只是�ؓ(f��)你做了很��的一点事.首先,它创��Z��个名为home_url的方�?因此上面的命名规�?前期的请求�ؓ(f��):
redirect_to :controller=>'main',:action=>'start' 现在�?
redirect_to home_url

因�ؓ(f��)*_to�Ҏ(gu��)��被重写的方式,在上面的情况,你没有将参数传递给命名路径,你也可以��它传递给一个引用的�Ҏ(gu��)��.
redirect_to :home_url

注意:��命名�\径做��Z��个符号已�l�取消了,在rails2.0��被删除.

�q�个也能应用于是tests.如果在你的controller里有redirect_to home_url,也可以用 assert_redirect_to home_url.

*_url�Ҏ(gu��)��需要一个唯一的可选参�?�q�个参数是一个hash,插入url_for之中,�q�样做就是�ؓ(f��)了当用redirect_to,link_to时命名规则可以参数化.

你如果说有这��L(f��ng)��route

map.user_page 'users/:user',:controller=>'users',:action=>'show'

你可以这样做

link_to @user.username,user_page_url(:user=>@user)

注释:�q�个仅仅象普通的routes,表单是path_part/:symbol.在上面的例子�?user�q�部分将只展�C�在路径�?�q�不严格与controller相关�?users/只是path生成的部�?
上面的例子生�?lt;a href="http://localhost/users/7">http://localhost/users/7
比如:

:user 是你定义的参数名�U?如果定义两个一模一��L(f��ng)��路径,很可能得不到你想要的�l�果.对于routes,定义默认�?

当用参数来命名routes,你必��M��递参数给assert中的命名规则.如果在你的controller中有redirect_to user_page_url(:user=>@user), 你需要有assert_redirected_to user_page_url(:user=>@user).controller中@user的id必须与test中的@user的id匚w��.

除了[route_name]_url�Ҏ(gu��)��,你可以用hash_for_[route_name]_url�Ҏ(gu��)��,�q�个�Ҏ(gu��)��包装hash,没有调用url_for

所有的reoute��其它的命名规则用map.connect提供�l�你.
