]]>(1)首先要在域名服务商端做一个泛域名解析. 我用的是godaddy.com,就新建一个a记录(host=*,point to指向我的服务器的ip),这样所有二级域名都会转到我的服务器来了
(2)接着在web.xml配一个自已写的域名过滤器,
过滤器的代码如下。这里先将二级域名和全球域名和用户id的映射,保存在一个数据表里, 然后访问进来时对地址做一个判断, 再取出对应的用户id. 再转一下就行了. 我的静态文件都在static目录，所以还加了一个static的判断。
比如: 用time对应用户id为6,则访问效果有 相同, 不过地址栏还是显示。
再比如：htttp://www.userdomain.com/board/21，这个是用户id为6的全球域名，访问效果也和上面一样。

其他一些小技巧：
（１）为了便于本机测试，可以修改windows 的hosts文件。我的如下：
127.0.0.1 localhost
127.0.0.1 you.com
127.0.0.1 www.you.com
127.0.0.1 time1.you.com
127.0.0.1 time2.you.com
127.0.0.1 6.you.com
127.0.0.1 www.bobo.com
127.0.0.1 you.com
127.0.0.1 www.you.com
127.0.0.1 time1.you.com
127.0.0.1 time2.you.com
127.0.0.1 6.you.com
127.0.0.1 www.bobo.com
（２）web页的各种地址则要注意相对路径的问题。主要考虑
首先设置，或其中地址最后要加一个/
然后页面中其他地址前面不加/，就是相对地址（以地址栏为基础）。加上/，则是绝对地址。

]]>在ubuntu7.10中的gvim出现乱码，这时需要在主目录下的“.vimrc”文件中加上定义字体的一句。我用的是“微软雅黑”字体所以此句为：
set guifont=yahei\ consolas\ hybrid\ 10
注意：字体名中有空格的，用斜杠分开，而且斜杠后面一定要有一个空格。10是字体大小，前面有一个空格。

]]>这个设计其实很简单，就是“引擎 配置“--主体页面只定义一个rthml，可以把它看做页面引擎，然后用一个配置文件指定了页面所应具有的模块和数据。 页面模块就象一个个装有数据的盒子，通过“页面引擎 配置文件”把这些盒子组合起来，象搭积木一样。页面引擎是各用户共用的，配置文件是各用户独有的，这样一装配起来，就形成了用户的个性化页面。
剩下的重点就是怎么定义配置文件。首先是要划清配置文件的责任界线----它只负责定义盒子里的数据，还有盒子的嵌套关系，而大小和位置等布局方面则全部交给css去负责。
上面是初步想法，下面看看具体实现，代码仅供参考
以下是某个用户的配置文件（我没用xml，而是用yaml）。board_1是指id=1这个栏目所用的配置定义。topcontent是一个
的id值，我把每个栏目的页面分成topcontent顶、sidecontent边（左或右由css决定）、primarycontent
主要、bottomcontent底。topic是指添加一个模块（盒子），显示一个主题内容。和topic类似是还有显示图像的image、显示主题列
表的topics、显示分类列表的categories等等等等。它们各有不同的属性值，比如topic模块，它需要定指它的主题id，以及它所用的
view(topics/_show_hot.rhtml or topics/_show.rhtml等等)。
（虽然这个配置文件抽象得还不够，但这样子已经可以解决我的需要了，那就暂时这样先了。）
template.yml
然后在controller里把配置文件读入，再转化成模型类。我把各个界面模块看做一个个盒子box
这是它的顶级box
这是topic模块的
这是image模块的
.....等 等， 其他的box子类大同小异
然后在一个controller里把这些配置信息转成box模型类
最后是它页面引擎（逻辑代码和页面代码混在一起，比较丑陋）
（虽然这个配置文件抽象得还不够，但这样子已经可以解决我的需要了，那就暂时这样先了。）

- board_1:
- - topcontent:
- - topic:
- topic_id: 7

ruby 代码
- class topicbox < box
- attr_accessor :topic_id
- end
这是image模块的
ruby 代码
- class imagebox < box
- attr_accessor :url
- end
.....等 等， 其他的box子类大同小异
然后在一个controller里把这些配置信息转成box模型类
ruby 代码
- templates = yaml::load(file.read("public/uploads/#{user_id}/config/template.yml"))
- template = templates.find{|o| o[0]=="board_#{@board.id}" }
- args = template[1]
- @boxes = []
- args.each do |arg1_hash|
- arg1_hash.each do |key1, value1|

- arg2_hash.each do |key2, value2|
- case key2
- when 'topics'
- box = topicsbox.new
- box.board_id = value2['board']
- box.per_page = value2['per_page']||2
- box.view = value2['view']||'index_simple'
- board_box.boxes << box

- box.topic_id = value2['topic_id']
- box.view = value2['view']||'util/box'
- board_box.boxes << box
- end
- end
- end
- end
- end
最后是它页面引擎（逻辑代码和页面代码混在一起，比较丑陋）
ruby 代码
- <% @boxes.each do |box1| %>
- <% box1.boxes.each do |box2|
- p1 box2.class.to_s
- case box2.class.to_s
- when 'topicsbox'
- board_id = box2.board_id
- if board_id
- board = board.find(board_id)
- topics = topic.by_board_id(board_id, :per_page => box2.per_page)
- %>
- <%= render(:partial => "topics/#{box2.view}", :locals => {:title =>board.title, :topics => topics })%>
- <%end
- when 'categoriesbox'
- board_id = box2.board_id
- if board_id
- board = board.find(board_id)
- categories = board.categories
- %>
- <%= render :partial => "categories/#{box2.view}", :locals => {:board =>board, :categories => categories } %>
- <%end%>
- <%when 'imagebox'%>
- <%= box_tag :header=>false%>
- <%=image_tag(box2.url, :border => 0) %>
- <%= end_box_tag %>
- <%when 'topicbox'
- topic = topic.find(box2.topic_id) %>
- <%=render(:partial => "#{box2.view}", :locals => {:title =>topic.title, :content => topic.content, :topic => topic })%>
- <%end
- end%>
这样，以后想在页面上增加删除什么模块，修改配置文件就行了。当然给用户用，还必须得用ajax来写个gui界面，总不能让用户手工去改配置文件吧。

在阅读fckeditor的源码之后，做如下处理。1. 新增两个javascript函数。
var currentimagetextid;
//fckeditor的文件浏览窗关闭后，会调用此函数，并把所选图片的url传入。
function set{
document.getelementbyid(currentimagetextid).value=url;
}
//imagetextid: 图片文本框的id值
//uploadpath: 服务器的图片目录
//type: 浏览类型，值可为image/flash/file/media，如果为空字串，则表示浏览所有类型的文件
function openimagebrowser(imagetextid, uploadpath, type ) {
currentimagetextid = imagetextid;
window.open('/javascripts/fckeditor/editor/filemanager/browser/default/browser.html?uploaded='uploadpath'&type='type'&connector=/fckeditor/command','browse/upload images','toolbar=no,status=no, resizable=yes,dependent=yes, scrollbars=yes,width=600,height=400')
}
//fckeditor的文件浏览窗关闭后，会调用此函数，并把所选图片的url传入。
function set{

1.修改fckeditor_controller.rb，把它那几个private方法修改如下：private
def current_directory_path
base_dir = "#{rails_root}/public"
#todo 在创建用户时，就建立好目录。这时可以去掉这部份代码，提高运行效率。
("#{params[:uploaded]||uploaded}/#{params[:type]}").split('/').each do |s|
next if s==''
base_dir = '/' s
dir.mkdir(base_dir,0775) unless file.exists?(base_dir)
end
check_path("#{base_dir}#{params[:currentfolder]}")
end
def upload_directory_path
uploaded = @request.relative_url_root.to_s"#{params[:uploaded]||uploaded}/#{params[:type]}"
"#{uploaded}#{params[:currentfolder]}"
end
def check_file(file)
# check that the file is a tempfile object
unless "#{file.class}" == "tempfile" || "#{file.class}" == "stringio"
@errornumber = 403
throw exception.new
end
file
end
def check_path(path)
exp_path = file.expand_path path
if exp_path !~ %r[^#{file.expand_path(rails_root)}/public#{params[:uploaded]||uploaded}]
@errornumber = 403
throw exception.new
end
path
end
另外，它前面的常量uploaded_root也没用了，可以删掉。
2. 在上面的代码中params[:uploaded]是关键，它就是我们动态定义的上传目录。该值来自于fckeditor的一些html页面，它是通过get参数传入的。修改browser.html文件（如下粗体部份），在它的url请求中把我们定义目录加入到get参数列中，这样它就可以传到fckeditor_controller.rb里了。
var sserverpath = geturlparam( 'serverpath' ) ;
if ( sserverpath.length > 0 )
oconnector.connectorurl = 'serverpath=' escape( sserverpath ) '&' ;
var suploaded = geturlparam( 'uploaded' ) ;
if ( suploaded.length > 0 )
oconnector.connectorurl = 'uploaded=' escape( suploaded ) '&' ;
oconnector.resourcetype = geturlparam( 'type' ) ;
oconnector.showalltypes = ( oconnector.resourcetype.length == 0 ) ;
3. 上面的geturlparam( 'uploaded' ) 的值来自于fckcustom.js。修改fckcustom.js（如下粗体部份），把uploaded加入到get参数列中。

fckrelativepath = '';
// don't change these
fckconfig.linkbrowserurl = fckconfig.basepath 'filemanager/browser/default/browser.html?connector='fckrelativepath'/fckeditor/command';

fckconfig.fontnames = '微软雅黑;宋体;黑体;隶书;楷体_gb2312;arial;comic sans ms;courier new;tahoma;times new roman;verdana' ;

fckconfig.autodetectlanguage = false ;
fckconfig.defaultlanguage = 'zh-cn' ;
fckconfig.fontnames = '微软雅黑;宋体;黑体;隶书;楷体_gb2312;arial;comic sans ms;courier new;tahoma;times new roman;verdana' ;

['textcolor','bgcolor'],
['link','unlink','anchor'],
['image','flash','table','rule','smiley'],
'/',
['style','fontformat','fontname','fontsize']
] ;
4. 上面fckconfig.uploaded的值来自于fckeditor.rb。在fckeditor.rb中加入一句（如下粗体所示）。
javascript_tag( "var ofckeditor = new fckeditor('#{id}', '#{width}', '#{height}', '#{toolbarset}');\n"
"ofckeditor.basepath = \"#{base_path}\"\n"
"ofckeditor.config['customconfigurationspath'] = '../../fckcustom.js';\n"
"ofckeditor.config['uploaded'] = '#{options[:path]}';\n"
"ofckeditor.replacetextarea();\n")
"ofckeditor.basepath = \"#{base_path}\"\n"
"ofckeditor.config['customconfigurationspath'] = '../../fckcustom.js';\n"
"ofckeditor.config['uploaded'] = '#{options[:path]}';\n"
"ofckeditor.replacetextarea();\n")
5.不过上面ofckeditor.config['uploaded']的值要传到fckcustom.js的fckconfig.uploaded里，还需要修改fckeditorcode_gecko.js和fckeditorcode_ie.js（这两个文件对javascript进行了压缩处理，修改起来较难操作）。我是参考了ofckeditor.config['customconfigurationspath'] 这个参数的载入实现，才找到这种鸟不生蛋的地方。搜索这两个文件的关键字customconfigurationspath，找到如下一行，然后加入一个else if判断(如下粗体所示）。
if (d=='customconfigurationspath') fckconfig[d]=e;else if (d=='uploaded') fckconfig[d]=e;else if (e.tolowercase()=="true") this.pageconfig[d]=true;
6.最后在fckeditor.rb里的#{options[:path]}来自于我们前台的view了。如下粗体所示，把标准的fckeditor_textarea新增加了一个参数，其中params[:user_id]是把用户的id值做为目录名。这样就实现了动态改变fckeditor的上传目录。
<%=fckeditor_textarea(:topic, :content, :ajax => true, :toolbarset => 'simple', :height => '400px', :path => "/uploads/#{params[:user_id]}") %>
修改完后需要重启web服务，最后别忘记把public/javascripts/fckeditor和vendor/plugins/fckeditor/public/javascripts同步一下，原因见http://www.blogjava.net/chengang/archive/2007/09/24/147867.html

首先，我们来看看fckeditor在rails中的运行特性，其插件主要是安装在vendor/plugins/fckeditor。主要的代码在vendor/plugins/fckeditor/public/javascripts，其中fckcustom.js是配置文件，另外更深一层的子目录fckeditor中还有一个fckconfig.js也是配置文件。fckcustom.js配置的优先顺序大于fckconfig.js，因此一般修改fckcustom.js就可以了，不必去动fckconfig.js。在启动webrick( ruby script/server)时，会自动把vendor/plugins/fckeditor/public/javascripts的内容复制到public/javascripts目录。因此如果你修改了fckeditor的配置文件之后，需要把复制到public/javascripts目录的fckeditor相关文件删除掉，然后再重启webrick。当然，你也可以直接修改public/javascripts目录的fckeditor的缓存的配置文件，这样不必重启webrick，就可以立即看到修改效果。不过建议你在完成修改后，同时也要更新vendor/plugins/fckeditor/public/javascripts下的配置文件，毕竟public/javascripts里的应该算是临时文件。
1.中文化
在fckcustom.js里加入两项（粗体显示）
fckconfig.skinpath = fckconfig.basepath 'skins/silver/';
fckconfig.autodetectlanguage = false ;
fckconfig.defaultlanguage = 'zh-cn' ;
fckconfig.autodetectlanguage = false ;
fckconfig.defaultlanguage = 'zh-cn' ;
2. 定制fckeditor的工具栏
修改fckcustom.js里的如下项目，增删改自便。
fckconfig.toolbarsets["simple"] = [ 。。。 。。。
这里要注意一点，有些网上文章把:toolbarset写成了:toolbarkit，这是错误的。如果你发现对工具栏的配置不起作用，那么要检查一下。正确的写法如下：
<%=fckeditor_textarea(:topic, :content, :ajax => true, :toolbarset => 'simple', :width => '100%', :height => '300px') %>

使用依然兼容老的方式，你也可以传入一个哈希表，把模型字段显示成对应的中文，示例如下：
<%=
h = {'username'=>'用户名', 'password'=>'密码'}
error_messages_for h, :user
%>
h = {'username'=>'用户名', 'password'=>'密码'}
error_messages_for h, :user
%>
另外，还要在environment.rb的最后插入以下代码：
errors = activerecord::errors.default_error_messages
errors[:taken] = '已经被使用'
errors[:blank] = '不能为空'
errors[:taken] = '已经被使用'
errors[:blank] = '不能为空'

但一直搜不到它支持ajax分面的方法 ，于是我参考它分页方法的源代码(位于:vendor/plugins/will_paginate/lib/will_paginate/view_helpers.rb)，稍微改写，变成了一个支持ajax的分页方法。以下代码复制到application_helper里即可。#-----------------------------------------
# will_paginate插件的ajax分页
#-----------------------------------------
@@pagination_options = { :class => 'pagination',
:prev_label => '上一页',
:next_label => '下一页',
:inner_window => 4, # links around the current page
:outer_window => 1, # links around beginning and end
:separator => ' ', # single space is friendly to spiders and non-graphic browsers
:param_name => :page,
#add by chengang
:update =>nil, #ajax所要更新的html元素的id
:url_suffix => '' #url的后缀，主要是为了补全rest所需要的url
#add end
}
mattr_reader :pagination_options
def will_paginate_remote(entries = @entries, options = {})
total_pages = entries.page_count
if total_pages > 1
options = options.symbolize_keys.reverse_merge(pagination_options)
page, param = entries.current_page, options.delete(:param_name)
inner_window, outer_window = options.delete(:inner_window).to_i, options.delete(:outer_window).to_i
#add by chengang
update = options.delete(:update)
suffix = options.delete(:url_suffix)
url = request.env['path_info']
url = suffix if suffix
#add end
min = page - inner_window
max = page inner_window
if max > total_pages then min -= max - total_pages
elsif min < 1 then max = 1 - min
end
current = min..max
beginning = 1..(1 outer_window)
tail = (total_pages - outer_window)..total_pages
visible = [beginning, current, tail].map(&:to_a).flatten.sort.uniq
links, prev = [], 0
visible.each do |n|
next if n < 1
break if n > total_pages
unless n - prev > 1
prev = n
#change by chengang
text = (n==page ? n : "[#{n}]")
links << page_link_remote_or_span((n != page ? n : nil), 'current', text, param, update, url)
else
prev = n - 1
links << '
'redo
end
end
#change by chengang
links.unshift page_link_remote_or_span(entries.previous_page, 'disabled', options.delete(:prev_label), param, update, url)
links.push page_link_remote_or_span(entries.next_page, 'disabled', options.delete(:next_label), param, update, url)
#change end
content_tag :div, links.join(options.delete(:separator)), options
end
end
protected
def page_link_remote_or_span(page, span_class, text, param, update, url)
unless page
content_tag :span, text, :class => span_class
else
link_to_remote text, :update => update, :url => "#{url}?#{param.to_sym}=#{page}", :method=>:get
end
end
在view中的使用如下所示:
<%=will_paginate_remote @topics, :update => 'topiclist', :url_suffix => url_suffix%>

环境：ubuntu linux 7.0.4 ruby 1.8.5 rails 1.2.3 fckeditor 0.4.1
直接从它的subversion库里取得该rails插件。先进入到你的项目根目录，再执行如下命令
ruby script/plugin install svn://rubyforge.org/var/svn/fckeditorp/trunk/fckeditor
其他说明：
(1)你的linux必须先安装了subversion。（ubuntu里用新立得搜subversion即得）
(2)把命令中的install 改为 destory，可以删除安装。
(3)我取到的是2007年4月份最后更新的, v 0.4.1版
(4)fckeditor安装在项目根目录下的vendor/plugins/fckeditor 里，
(5)vendor/plugins/fckeditor里的readme很值得一读，我碰到ajax问题，查了所以网上的中文资料都没有提到，在这个readme却有。
用如下语句在页面里含入它的javascript库
<%= javascript_include_tag :fckeditor %>
或<%= javascript_include_tag "fckeditor/fckeditor" %>
在需要富文本的form表单用如下语句生成一个富文件编辑框：
<%= fckeditor_textarea("topic", "content", :toolbarset => 'simple', :width => '100%', :height => '200px') %>
说明：topic对应模型对象,content对应它的字段。也就是要求当前页要有@topic这个实例变量。
如果是用了ajax，则需要在form_remote_tag加上一个before项
<%= form_remote_tag(:update => update,
:before => fckeditor_before_js('topic', 'content'),
:url => {:controller => 'topics', :action => 'create', :template => 'show'} )%>
:before => fckeditor_before_js('topic', 'content'),
:url => {:controller => 'topics', :action => 'create', :template => 'show'} )%>
并且富文件编辑框要加一个ajax=true的选项：
<%= fckeditor_textarea(:topic, :content, :ajax => true, :toolbarkit => 'simple', :width => '100%', :height => '600px') %>
在使上传图片的功能时碰到了错误。弹出出alert对话框，显示：error on file upload.error number: 403
在日志里显示如下，表面上看好象是路由配置的问题
actioncontroller::routingerror (no route found to match "/fckblank.html" with {:method=>:get}):
/var/lib/gems/1.8/gems/actionpack-1.13.3/lib/action_controller/routing.rb:1292:in `recognize_path'

/usr/lib/ruby/1.8/webrick/server.rb:162:in `start'
/usr/lib/ruby/1.8/webrick/server.rb:162:in `start_thread'
最后在http://blog.caronsoftware.com/articles/2006/12/03/fckeditor-0-4-0-released#comment-1745找到了答案，这是一个bug
解决方法 ：
修改：vendor/plugins/fckeditor/app/controller/fckeditor_controller.rb
将原来的
unless "#{file.class}" == "tempfile"
改为
unless "#{file.class}" == "tempfile" || "#{file.class}" == "stringio"
