Rails - How do I run a loop inside of a mailer?

Question

So it turns out mailers hate loop inside of them. So here's my loop.

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

Which returns this went sent through actionmailer in rails 2.3.5 :

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

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

How would you accomplish this?

Answer 1

try

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

and watch your white sapce

Answer 2

Problem is with using both for and each. Try this:

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

or this:

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

I don't use haml. Does it need end to close block?

Answer 3

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