想知道到Fedora ruby工程系统的真相么，想知道Fedora ruby工程系统中藏有的内在奥义么，只有我来给大家全面讲解介绍Fedora ruby工程系统***个工程建立rails工程rails --Fedora ruby工程=path 工程锁在的path修改environment里的database.yml然后做例子重启服务器Fedora ruby工程 script\server关闭control c访问地址http://localhost:3000/chinese/list
- ruby script\generate model paper修改db\migrate\新的rb文件，里边加：t.column :name,:string
- rake db:migrate
- ruby script\generate controller paper
- ruby script\generate scaffold paper paper
fc6更方便的安装包下一个yumexsudo yum install yumex在yumex可以直接选一个安装用yum的话就要输命令字体问题操作系统语言选择了english，中文就变成了乱码。
需要安装字体* 字体安装将Microsoft Windows(windows\fonts\)的相应TrueType拷贝到Fedora ruby工程相应目录。我是放在/usr/share/fonts/windows目录下。然后以root执行下面的命令
- cd /usr/share/fonts/windows
- ttmkfdir .
- cp fonts.scale fonts.dir
- chkfontpath --add /usr/share/fonts/windows
以下是我安装的字体文件
- (Arial) - arial.ttf arialbd.ttf arialbi.ttf ariali.ttf
- (Tahoma) - tahoma.ttf tahomabd.ttf
- (Verdana) - verdana.ttf verdanab.ttf verdanai.ttf verdanaz.ttf
- (GB) - simsun.ttc
- (BIG5) - mingliu.ttc
装了gb和big5后，网页和openoffice里的中文就没问题了。开发oracle应用需安装OCI从http://Fedora ruby工程forge.org/frs/?group_id=256&release_id=12694上下载然后cmd中运行 Fedora ruby工程 ruby-oci8-1.0.0-rc3-mswin32.rb即安装成功，就可以rake db:migrate了.
