Rails 3: client_side_validations throws a warning about starting a unique check

Question

I am using the client_side_validations gem to do form validation in rails 3.

everything works fine except when firefox / ie throws a javascript warning when a unique ajax check is executed and returns a 404 error message.

The author says that record 404 was not found and therefore unique;

Can I handle this.

Answer 1

The error you see is that the remote check cannot find the resource on the server. It is expected that if a resource is not found, the resource is unique.

            self.body   = '' # changed from true
          else
            self.status = 200
            self.body   = 'false'
