这个需求。我最初的解决方法是创建几个典型的rhtml布局组合。但这远远不够，而且不灵活，在形式上也不统一。于是我再次修改了设计，之后似乎可以基本
解决这个问题了。希望感兴趣的朋友一起来讨论。<br /><br />
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。<br /><br />
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。<br /><br />
上面是初步想法，下面看看具体实现，代码仅供参考<br /><br />
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<div>&lt;div&gt;的id值，我把每个栏目的页面分成<span>topContent顶、sideContent边（左或右由CSS决定）、</span><span>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)。<br /><br />（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</span><span></span><span>就</span><span>暂时</span><span>这样先了。）<br /><br /></span>template.yml<br /><div class="dp-highlighter"><div class="bar"> </div><ol start="1" class="dp-j"><li class="alt"><span><span>board_2:  </span></span></li><li class=""><span>  </span></li><li class="alt"><span>board_1:  </span></li><li class=""><span>- topContent:  </span></li><li class="alt"><span>  - topic:  </span></li><li class=""><span>      topic_id: <span class="number">7</span><span>  </span></span></li><li class="alt"><span>      view: topics/show_hot  </span></li><li class=""><span>- sideContent:  </span></li><li class="alt"><span>  - image:  </span></li><li class=""><span>      url: /images/news.jpg  </span></li><li class="alt"><span>  - categories:  </span></li><li class=""><span>      board: <span class="number">5</span><span>  </span></span></li><li class="alt"><span>      view: tree  </span></li><li class=""><span>  - topics:  </span></li><li class="alt"><span>      board: <span class="number">5</span><span>  </span></span></li><li class=""><span>      per_page: <span class="number">4</span><span>  </span></span></li><li class="alt"><span>      view: index_simple  </span></li><li class=""><span>  - topics:  </span></li><li class="alt"><span>      board: <span class="number">6</span><span>  </span></span></li><li class=""><span>- primaryContent:  </span></li><li class="alt"><span>  - topics:  </span></li><li class=""><span>      board: <span class="number">4</span><span>  </span></span></li><li class="alt"><span>      view: index  </span></li><li class=""><span>  - topic:  </span></li><li class="alt"><span>      topic_id: <span class="number">7</span><span>  </span></span></li><li class=""><span>      view: util/box  </span></li><li class="alt"><span>  </span></li><li class=""><span>board_3:  </span></li></ol></div><br />
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<br />
这是它的顶级Box<br /><div class="code_title">ruby 代码</div><div class="dp-highlighter"><div class="bar"> </div><ol start="1" class="dp-rb"><li class="alt"><span><span class="keyword">class</span><span> Box  </span></span></li><li class=""><span>  attr_accessor <span class="symbol">:html_id</span><span>, </span><span class="symbol">:view</span><span>, </span><span class="symbol">:boxes</span><span>  </span></span></li><li class="alt"><span>  <span class="keyword">def</span><span> initialize</span><span><br /></span></span></li><li class=""><span>    <span class="variable">@boxes</span><span>=[]  </span></span></li><li class="alt"><span>  <span class="keyword">end</span><span>  </span></span></li><li class=""><span><span class="keyword">end</span><span>  </span></span></li></ol></div><br />
这是topic模块的<br /><div class="code_title">ruby 代码</div><div class="dp-highlighter"><div class="bar"> </div><ol start="1" class="dp-rb"><li class="alt"><span><span class="keyword">class</span><span> TopicBox &lt; Box  </span></span></li><li class=""><span>  attr_accessor <span class="symbol">:topic_id</span><span>  </span></span></li><li class="alt"><span><span class="keyword">end</span><span>  </span></span></li></ol></div><br />
这是Image模块的<br /><div class="code_title">ruby 代码</div><div class="dp-highlighter"><div class="bar"> </div><ol start="1" class="dp-rb"><li class="alt"><span><span class="keyword">class</span><span> ImageBox &lt; Box  </span></span></li><li class=""><span>  attr_accessor <span class="symbol">:url</span><span>  </span></span></li><li class=""><span><span class="keyword">end</span><span>  </span>   <br /></span></li></ol></div><br />
.....等 等， 其他的Box子类大同小异<br /><br />

/><div align="center">文/陈刚  <a title="www.chengang.com.cn" href="www.chengang.com.cn">www.chengang.com.cn</a><br /></div>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。<br /><br />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。<br
