Good night,

When creating a client I have the following validation that is generating problems for me. How can I do it to eliminate it?

nif field (vat)

release: odoo12

I do the following:

The NIF [xxxxxxxx] for the company [xxxxxxx.] does not appear to be valid. Note: the expected format is PERxxxxxxx or PED1xxxxxxxx

from odoo import api, fields, models

class ResPartner(models.Model):

    _inherit = 'res.partner'

    vies_passed = fields.Boolean(

        string="VIES validation",default=False, readonly=True)

    @api.model

    def simple_vat_check(self, country_code, vat_number):

        res = super(ResPartner, self).simple_vat_check(

            country_code, vat_number,

        )

        partner = self.env.context.get('vat_partner')

        if partner and self.vies_passed:

            # Can not be sure that this VAT is signed up in VIES

            partner.update({'vies_passed': False})

        return res

    @api.model

    def vies_vat_check(self, country_code, vat_number):

        partner = self.env.context.get('vat_partner')

        if partner:

            # If there's an exception checking VIES, the upstream method will

            # call simple_vat_check and thus the flag will be removed

            partner.update({'vies_passed': True})

        res = super(ResPartner, self).vies_vat_check(country_code, vat_number)

        if not res:

            return self.simple_vat_check(country_code, vat_number)

        return res

    @api.constrains('vat')

    def check_vat(self):

        for partner in self:

            partner = partner.with_context(vat_partner=partner)

            super(ResPartner, partner).check_vat()

    def check_vat_es(self, vat):

        return True
