[SSL CA] 超便宜的 SSL CA 憑證
https://www.ssls.com/

購買安裝流程簡述:(Positive SSL)

  1. 先到 Linux 產生一組網站的 crt 和 key (domain 要與欲設定網站相同)
  2. 下訂單購買,完成後需要填入剛剛的 crt
  3. 填資料、Email 會有幾封驗證信、最後會收到一個 zip 檔案
  4. 需要把這幾個 combine 在一起:

cat your_domain_name.crt COMODORSADomainValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt > bundle.crt

  1. 組合完成的 bundle.crt + 一開始產生的 .key 擋最後要 copy 到 nginx 上做設定 (可以直接用 capistrano 自動設定 SSL)

[Rails Core] 核心模組 Railtie & Engine

Railtie: 提供開發者從外部增加 rails 載入各種階段的 hook (initializer, prepare, ... etc)
http://api.rubyonrails.org/v4.1.4/classes/Rails/Railtie.html

Engine: 繼承自 Railtie,能夠實作出可掛載的 raills application gem,觀察差異是 Railtie 階段無法取得使用的 app 某些資訊:例如掛載 migration path 等等。
http://edgeapi.rubyonrails.org/classes/Rails/Engine.html

包 gem 擴充 rails 物件時機點:

a. 需要 application context 則掛在 Railtie 或 Engine 內:
https://github.com/plataformatec/devise/blob/master/lib/devise/rails.rb#L16

b. 不需要 application context 的狀況則可直接掛載:
https://github.com/collectiveidea/awesome_nested_set/blob/f823ffb304ccf5ca9c4f14b60ff1f45ad2c3f440/lib/awesome_nested_set.rb#L3
