I've been on a project where we had added a method something like the following class Array def only_element raise 'array has too many elements' if length > 1 first end end and so we used to get the only element out of arrays that way. Having an array in which you are sure there is only a single element is something that many would call a smell. However, I think this is off topic for Rails core now. -- Tejas Dinkar http://www.nilenso.com Nilenso Software (formerly C42 Engineering) -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
