While Fabien's solution does exactly what you asked, I'd venture that what you asked is not what you want or need. Leave off the call to flatten - can you make the place where you use this simpler now?

I thought the same about html select rails helper but it was supposed to render it flatten, so be it ;)

Thanks Fabien for your refactoring.
I also need your help on this code snippet
http://www.refactormycode.com/codes/328-model-validations
Thanks In advance
In Following snippet I only want id & name of carriers as comma separated.
Following is the output I am expecting.
p @arr >> [1, "ATT Wireless", 2, "Alltel", 3, "Amritech", 4, "Boost", 5, "Cellular One"]
