The Enumerable ruby class is your friend!

Forget about for loops and trying to ouput an iterator.

Instead, in your ruby code, you can do:

1.@post.comments.each_with_index |post, index|  
2.  "Comment Number #{index}"  
3.  post.name  
4.end

And that will output the iteration number with your other data.

Ruby makes coding so much more fun.
