The code looks OK to me. Are you sure it's not a caching/stale record problem? Fire up a console and execute your code manually. If you see the same error try reloading the instance, eg: person.reload This will ensure you are looking at a current version from the database rather than a (possibly) stale version in Ruby memory. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
