# 在本地服务器建立 rubygems.org 的镜像缓存，以提高 gem 的安装速度
# 此配置设置缓存过期为1天，也就是说，新上的 gem 无法马上安装
# 做这个起什么作用？
# rubygems 的很多资源文件是存放到 Amazon S3 上面的，由于 GFW 对某些 S3 服务器又连接重置或丢包，导致 gem 安装异常缓慢或有时候根本无法连接安装。
# 而通过这种跳板的方式可以很好的解决这个问题，当然前提是 Nginx反向代理 服务器需要在国外

See question on stack overflow: http://stackoverflow.com/questions/28595636/rails-4-how-to-give-alias-names-to-includes-and-joins-in-active-record-que

- Model Student and model Teacher are both STI models with super class model User
- Model Story is a STI model with super class model Task
- includes() and joins(), both fails

Rails alias naming convention (includes() and joins())

- One model as parameter
  - is base model (includes(:users))
