brew install redis

Set up launchctl to auto start redis

$ ln -sfv /usr/local/opt/redis/*.plist ~/Library/LaunchAgents

/usr/local/opt/redis/ is a symlink to /usr/local/Cellar/redis/x.y.z (e.g., 2.8.7)

為什麼用 Ransack

在網站中提供搜尋、篩選與排序功能在現在的網站中已是基本需求，畢竟大家的耐心，在 Ruby on Rails 中，由於採用了 ActiveRecord 作為 ORM 框架的緣故，要快速的組出 Search Query 並非難事。

基本上只要搭配上 Form Object 與 Query Object 模式，要優雅的完成好維護的搜尋模組還算是容易，但當你想要快速完成搜尋功能的時候，Ransack 絕對是你的好夥伴。

Ransack 的基本設定極其簡單，只要安裝完後基本上就可以使用了。
