Rails - 如何在邮件程序中运行循环？

Question

所以事实证明邮寄者讨厌他们内部的循环。所以这是我的循环。

- for ["love", "hate", "war"].each do |f|
  = f

返回的内容通过rails 2.3.5中的actionmailer发送：

promotion_reminder.html.haml:17: syntax error, unexpected ';', expecting tCOLON2 or '[' or '.'
...ry_temp));}\n", 0, false);end;_hamlout.push_text("      </di...

On line #17 of app/views/notifier/promotion_reminder.html.haml

14:         
15:         - for ["love", "hate", "war"].each do |f|
16:           = f

你将如何实现这一目标？

Answer 1

问题在于同时使用for和each。试试这个：

- ["love", "hate", "war"].each do |f|
  = f

或者这个：

- for f in ["love", "hate", "war"] do
  = f

我不使用haml。是否需要end来关闭阻止？

Answer 2

试

- ["love", "hate", "war"].each do |f|
  = f

并观察你的空白区域

Answer 3

- ["love", "hate", "war"].each do |f|
  = f
