Not sure what you mean - are you intending the if statement on the size to apply to the statement above? Also note that find_all_* and friends will *always* return an Array (or should - if you're getting nil out of a find_all, file a Rails bug!), so checking @blogs seems a little paranoid. --Matt Jones -- You received this message because you are subscribed to the Google Groups "Hobo Users" group.
