Re: Using Any compound validation

Hi Richie,
I had a similar problem some time ago and solved it subclassing  
FormValidator() and adding my own validator to the list of the chained  
validators. Something like the following:

class ThisOrThat(FormValidator):
     messages = {
             'thisorthat': u"This or that must have a valid input"
             }

     def validate_python(self, values, state):
         this = values('this').strip()
         that = values('that').strip()

         if not (this or that):
             raise Invalid(
                     self.message('thisorthat', state),
                     values,
                     state,
                     error_dict={'this': Invalid(
                          self.message('thisorthat', state),
                          values, state),
                          'that': Invalid(
                          self.message('thisorthat', state),
                          values, state)
                          })

I don't know if this is the best approach or not, I'm still a beginner  
with FormEncode. Anyway I hope this can help you a bit.

Cheers,
  Andrea
