[TurboGears] Re: validator help

Hello,

you're try/except is handling both exceptions, SQL and your rise statement:

it should be something like:

class UniqueCourse(validators.FancyValidator):
    messages = {'unique': "A course by that name already exists"}

    def _to_python(self, name, state):
        try:
            Course.byName(name)
        except:
            raise validators.Invalid(self.message('unique',
state),name, state)
        return name


Regards

I'm trying to write a really simple validator, but it's not working for
me. The raise Invalid never happens. What am I missing?

# relevant Import
from turbogears import controllers, widgets, validators, identity

#validator class
class UniqueCourse(validators.FancyValidator ):
    messages = {'unique': "A course by that name already exists"}

    def _to_python(self, name, state):
        try:
            Course.byName(name)
            raise validators.Invalid(self.message ('unique',
state),name, state)
        except:
            return name

This seems like it should be really really simple but I'm just smashing
my head on it. Any help would be appreciated.
