- 2. OUTLINE • introduction • tutorial • Incompatibilities • gem upgradation
- 3. INTRODUCTION
- 4. HIGHLIGHT IN RAILS 4.0 • Ruby 2.0 preferred; 1.9.3 required • Strong Parameters • Turbolinks • Russian Doll Caching
- 5. STRONG PARAMETERS • 為了了解決mass- assignment的安全性問 題 • attr_accessible / attr_protected 並不適 ⽤用 • 把MVC分清楚
- 6. TURNOLINKS • Turbolinks for Rails (like pjax) • pjax: 只載入需要載入 的東⻄西 • turbolinks: 只重新載入 <body></body> • data-no-turbolink
- 7. RUSSIAN DOLL CACHING • view打cache的難題 • ⽤用updated_at當key => 使⽤用touch
- 8. HIGHLIGHT IN RAILS 4.1 • Spring application preloader • config/secets.yml • Action Pack variants • Action Mailer previews • Active Record enums
- 9. SPRING / SECRETS.YML • Spring • 縮短開發時間 • 在背景執⾏行行⼀一個rails app，執⾏行行rake的時候，rails 就不⽤用再重啟了了 • config/secret.yml • 把所有的secret統⼀一管理理
- 13. HIGHLIGHT IN RAILS 4.2 • Adequate Record：速度更更快(2x)的find_by • Web Console：⼤大家都看到了了 • Active Job • Asynchronous mails • Foreign key support
- 14. ACTIVE JOB • queuing system的統⼀一 接⼝口
- 15. ACTION MAILER • deliver! 已經無法使⽤用 • deliver_now / deliver_later
- 18. TUTORIAL
- 19. TUTORIAL • rvm install ruby-2.2.1 • localhost: 2.2.1 • server: 2.1.9 • rails app:update • use rails:update on 4.2 and earlier • bundle update
- 22. INCOMPATIBILITIES IN RAILS 4.0 • Strong parameters • default using dalli in ActiveSupport::Cache::MemCacheStore. • Model.all now returns an ActiveRecord::Relation
- 24. INCOMPATIBILITIES IN RAILS 4.1 • String#remove(pattern) as String#gsub(pattern,’') • Added Time.zone.yesterday and Time.zone.tomorrow.
- 25. INCOMPATIBILITIES IN RAILS 4.2 • render “foo/bar" => render template: ”foo/bar” • respond_with and the corresponding class-level respond_to have been moved to the responders gem. • Default Host for rails server • The *_filter family of methods have been removed from the documentation. Their usage is discouraged in favor of the *_action family of methods:
- 26. GEM UPGRADATION
- 27. UNINTIALIZED CONTENT ARE:SQLITERAL • 發⽣生時機：當cache_store使⽤用dalli，且dalli上已經 有rails 4以前的cache時 • 原因：rails4/dalli相依的arel改版後沒有Sqliteral了了 • 解決⽅方式： • 等到錯誤的cache過期 • 開⼀一個新的memcache
- 28. GOOGLE DOC 無法寫入資料 • 發⽣生時機：要連進google doc建立session時 • 原因：rails4相依的google-api-client改版後沒有 Google::APIClient::JWTAsserter了了 • 解決⽅方式： • 程式改寫
- 30. 改變了了RENDER JSON的預設格式 Rails 3 Rails 4
- 31. END
