请教从.net转来ruby,能否给点建议~
另外第一个ruby程序就搞不出来了...
MissingSourceFile in My testController#hello ,这是什么问题....

欢迎，我也是.Net社区的。没什么好建议，忘记C#吧。

呵呵,有点舍不得啊,但是运行第一个程序为什么搞不出呢,晕死...
MissingSourceFile in My testController#index

是不是需要sqlite3.rb文件来连接这个数据库阿。：）偶也不了解，瞎说下

rails 2.0 默认的数据适配器改成了sqlite了，大部分人都没装这个。照martin的去做，应该可以解决。

晕了,怎么装了sqlite3还不行...

报什么错？刚才那个随手写的，我编辑了下：http://www.ruby-lang.org.cn/foru ... romuid=321#pid10269

[ 本帖最后由 martin 于 2008-1-9 16:31 编辑 ]

第一个hello world的程序也必须要连数据库吗?

呵呵

现在在bash启动文件里加上一句：alias rails="rails -d mysql"。
加了这句之后就不能执行rails -v了，不过rails这个实用程序只是用来创建Rails应用程序而已。
