Nginx http proxy cache to mirror of Rubygems.org
# 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

FactoryGirl: How to define a value based on an already defined one.
# Say you have two columns: start_at, end_at
# When start_at is defined, you want end_at's value based on the start_at
# Here is the solution, passing a block to get the object of the context.
start_at Random.new.rand(14..45).days.from_now
end_at { |l| l.start_at + 2.hours }
# Full example
FactoryGirl.define do
