    prefix = 'animal'
    name = String(key=True)
    onomatopoeia = String()
    shouts = Boolean()

    def say(self):
        output = self.onomatopoeia
        if self.shouts:
            output = output.upper()
        return output

Animal('cow', 'moo', shouts=True).save()
cow = Animal.get('cow')
