i''m sorry for posting such a stupid (and somewhat unconnected)
question,
but i''ve been stuck on this for over a couple good hours (probably due
to a lack of knowledge in regexp) so if anyone could give a hand, i''d
most appreciate it...
i''m trying to validate my site against these characters
## thesechars ## *; '' * ^ } { [ ] >< |
and so i''ve decided i''d use validates_format_of
/^[^thesechars]$/
but it''s not working! is there a different method i should be using?
many thanks,
newbie

You may need to allow for some more validates_format_of /^[^thesechars]+$/ You may want to consider this around the other way though. Instead of forbidding chars, allow a restricted set. validates_format_of /^\w+$/ will restrict the values allowable (maybe too much so). You''ll need to check the docs to tune it to your specific need. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
