Validate that input doesn't contain default text?

I know I have written this before, but now I cannot find it. I want to make sure that my input doesn't contain 'Other...'. I know there's some lookbehind regex that can get that, but I have had nothing but errors when I try to use it in a validates_format_of block. Any suggestions?

Thanks,

And I'm using Ruby 1.8.7, which does not include lookbehind regex, come to find.

Write your own validation method that tests that the string doesn't
match /Other\.\.\./.

Best,
