i have define a http request like this:

@http.route('/user/register/',type='http',auth='none')

and call   method like this:

issuc = request.env['res.users'].sudo().do_register(uname,upwd)

groups_id = request.env.ref('base.group_user')
values = {
    'active': True,
    "login": uname,
    "password": pwd,
    "name": uname,
    'groups_id': groups_id,
    'company_id': 1,
    'partner_id': 1
}
rec = self.sudo().create(values)

raise ValidationError(_('The chosen company is not in the allowed companies for this user'))

So what is the correct way to create?
