使用 rails 2.2.2 自带的 scaffold 生成带命名空间的脚本架时(如 Admin::Product)，scaffold 会生成带命名空间的model(app/models/admin/product.rb)，并且生成的 controller 代码看起来也很怪异，不能工作，想到后面还有那么多 scaffold 要生成，一个一个手动改实不在符合 DRY 精神，So， 写个脚本做些自动清理调整的工作看来相当有必要。
when running scaffold came with rails 2.2.2 with namespace(i.e. Admin::Product), it generates new model with namespace(app/models/admin/product.rb) and controller code looks wierd, which normally you didn’t expect it, this script done some fixing for u
环境 Env
ruby 1.8.7 / gems 1.3 / rails 2.2.2
注意 Notice
脚本只能在 rails app 的根目录下运行
this script can only run in rails app root directory.
