I created the field 'children' as a string (can't remember why, perhaps because someone might enter 'none'??), so that doesn't work. Is there any big advantage to changing the field 'children' into an interger? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
