Is there a automatic counter variable?

Does ruby have anything where if I'm going through a do-while loop, or
a "3.times" loop or "for product in products" where there's a variable
that will tell me which iteration of the loop I'm on? Instead of
havign to declare my own counter = 0 and then increment it each time?

Seems like something Rails would have... I can't seem to find
anything on it.

Thanks guys.

something like this?

  (2..46).each {|i|
      puts "i is now: #{i}"
  }

irb(main):001:0> 5.times {|i| puts i }
0
1
2
3
4

irb(main):002:0> ['one', 'two', 'three'].each_with_index {|i,e| puts i, e}
one
0
two
1
three
2

Don't know if "for product in products" has anything, but you could always do "products.each_with_index".

Hey guys...

Looks good, the with_index is the option I was looking for... just
looked so messy having to declare a counter variable in a view...
thanks!
