I''m trying to make sure that a name contains no funky characters. Is
there some obvious reason why the following lines would have no effect?
validates_format_of :name, :with => %r{\w*}
validates_format_of :name, :with => %r{([A-Za-z])*}
With these lines in my model, I can enter almost any name (with
blanks, punctuation, etc.) and Rails accepts it.
On the other hand, if I add
validates_format_of :name, :with => %r{.*\.jpg}
validates_length_of :name, :minimum => 2
then rails rejects short names or names that don''t end in .jpg.

You probably want to use + (one or more matches). -- Fraser Campbell <fraser-Txk5XLRqZ6CsTnJN9+BGXg@public.gmane.org> http://www.wehave.net/ Georgetown, Ontario, Canada Debian GNU/Linux --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Actually, I forgot the ^ and $. That''s what made this regex match almost anything.
