这又是怎么了？完全不知道咋回事，我代码都没改，也报错。

为什么我部署的 ruby-china 运行的这么慢？

kenneth — Sun, 04 Nov 2012 15:29:00 +0800

我测试部署了一下 ruby-china 的论坛程序，但是我发现运行起来比较慢。一个请求要等好久，远比官方的论坛要久，请问大概是哪里的问题？部署这个程序，一般部署有没有什么地方需要调试优化一下？

Rails 怎么这么诡异？灵异现象？

kenneth — Fri, 03 Aug 2012 19:07:27 +0800

程序报错 undefined method `key?' for nil:NilClass 怎么也跑不起来。但是我什么修改也没修改，就用浏览器访问了几次，好了这啥现象？

用 acts-as-taggable-on 给文章加 tag 一般如何处理？

kenneth — Mon, 16 Jul 2012 19:34:29 +0800

在表单中加一个文本框，然后填写 tag? 代码逻辑如何处理？有木有简明一点的教程？

怎么连接不上 mysql?

kenneth — Mon, 16 Jul 2012 18:54:43 +0800

ActiveRecord::ConnectionTimeoutError

could not obtain a database connection within 5 seconds (waited 5.00015685 seconds). The max pool size is currently 5; consider increasing it.

重启 mysql，程序也跑不起来，为什么？有没有遇到过？

Rails 程序按 development 方式部署和 production 方式部署有什么不同？

kenneth — Tue, 26 Jun 2012 12:32:45 +0800

我用 develpment 方式部署能运行，但是 production 方式则不行。这两种方式部署要注意点什么，尤其是 production 方式。

Rails 模板中如何处理标题？

kenneth — Sun, 24 Jun 2012 22:28:42 +0800

模板页和详细页中如何处理标题 title? 定义在 layout/application.html.erb 中？应该如何处理？

为什么 404？http://ruby-china.org/cpanel

kenneth — Sat, 23 Jun 2012 00:24:39 +0800

看源码里面有网站的管理后台，为什么访问起来 404？

按教程安装 Homeland 出错，不知道为啥？

kenneth — Thu, 21 Jun 2012 23:33:09 +0800

按照：http://ruby-china.org/topics/2661 Rails 版本 3.2.5

NoMethodError in Homeland::TopicsController#index

用了 Devise 以后，出现 Routing Error 如何知道错在哪里？

kenneth — Thu, 21 Jun 2012 09:11:08 +0800

在 3000 端口正常，但是 apache passenger 下跑就出错，不知道什么原因？

为什么社区用 MongoDB 不用 Mysql 做持久化？

kenneth — Tue, 05 Jun 2012 17:13:09 +0800

出于什么考虑呢？没觉得 MongoDB 比 mysql 好用啊，或者效率高多少？开发效率高？为什么不用成熟的 Mysql ?
