Silly question
Hi there,
I know this is be a very minor issue, but considering
@users = User.find :all, :order => ''name''
_AND_
@user_pages, @users = paginate :user, :order_by => ''name''
by simplicity, shouldn''t the symbols :order and :order_by
be the same or both to both cases ?
I stumbled on them a couple of times yet :)
Thanks,

Now that I can sort my ''list''...is there a logical way of not repeating
