Dear Alll,

    I've inherited model "hr.applicant". I'd like to validate mobile phone in filed "hr.applicant.partner_mobile".

But the constrains does not execute. 

class MyRecruitment(models.Model):

    _inherit = ['hr.applicant']

    @api.one

    @api.constrains('partner_mobile')

    def _check_partner_mobile(self):

        pattern = re.compile("^[0]{1}[0-9]{9}$")

        if not bool(pattern.match(self.partner_mobile)):

            raise ValidationError(_('Invalid mobile phone number!.'))
