[Webware-discuss] formkit validator problems

[Alexander B. <ki...@pr...>]

I am trying to write my own validators following the examples that comes
with FormKit, but they always raise an exception - and I can't figure
out why (the example works). I also get the same exception at some of my
pages when using the validators that come with FormKit.

Here's the traceback:
Traceback (most recent call last):

    self._value =3D validator._attemptConvert(value)	# get the validated va=
lue, if possible
AttributeError: CompanyDoesNotExist instance has no attribute '_attemptConv=
ert'


Here's the code for the validator I wrote:
class CompanyDoesNotExist(BaseValidatorClasses.FormValidator,SitePage):
    """ Make sure a company doesn't exist before we add it """
    def validate(self,valueDict):
        if self.compExists(valueDict['name']):
            raise BaseValidatorClasses.InvalidField, "This company
already exists."

    def validatePartialForm(self):
        return 1
