Take a look at the code of FieldsMatch from formencode (for example).
As the validator works on the whole form you need to build an error
dict and place the error in the field's key you want the error to
appear at.
something like:
def validate_python(self, field_dict, state=None):
errors = {}
if there_is_an_error:
errors['foo'] = "Invalid input at foo"
raise Invalid("The form contains an error", field_dict,
state, error_dict=errors)
