Maintainable Rails View
Maintainable Rails View
Organize templates in good way
關於本書
本書是作者本人維護多個專案以後累積出來的 Rails View Pattern。意旨在解決 Rails View 在經歷多次需求變更後後不堪維護的問題。
這本書包含以下幾個主題：
* Helper 使用時機
* Helper Best Pratices
* Partial 使用時機
* Partial Best Pratices
* Helper 與 Partial 之外的整理武器
* Object-Oriented View
共十數招維護技巧。
從最粗淺的 Helper / Partial 維護一直到進階的 Object-Oriented View 封裝實踐。看完本書後絕對會在 Rails View 這方面的功力大增。
（P.S. 適合 Rails 經驗一年維護以上開發者）

在專案中必須使用 Helper 整理程式碼的原因
- 其一：在 View 裡面實作 LOGIC 是不好的。
- 其二：讓 View 更加直觀好維護。
- 其三：給 Code 取名字，容易尋找並複用成果。
- 其四： 不會被以前寫的 Code 害死。
