    def clean_name(self, name, is_blank):
        if is_blank or len(name.strip()) == 0:
            raise ValueError('Field "name" is required.')

        # Keep only ascii characters.
        return unicodedata.normalize('NFKD', name).encode('ascii', 'ignore')

}
swamper = CompanySwamper(data)
assert swamper.is_clean()
company = swamper.build_or_update(Company, ['name', 'github_address'])

assert company.name == 'Devhouse Spindle'
assert company.github_address == 'https://github.com/wearespindle'
