TypeError：無法連接'str'和'function'對象-Odoo v10社區

Question

我有此功能，我正在從v8遷移到v10

def search_partner_seniat(self, cr, uid, ids, context=None):
    """ Check vat of the partner and update iva rate
    """
    if context is None:
        context = {}
    this = self.browse(cr, uid, ids)[0]
    su_obj = self.env('seniat.url')
    rp_obj = self.env('res.partner')
    vat = this.vat.upper()
    res = {'name': _('The requested contributor does not exist'),
           'vat_subjected': False, 'vat': vat, 'wh_iva_agent': False,
           'wh_iva_rate': 0.0}

    if 'VE' in vat:
        vat = vat[2:]

    if rp_obj.check_vat_ve(vat, context=context):
        res = su_obj._dom_giver(cr, uid, vat, context)
    self.write(cr, uid, ids, res)

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'search.info.partner.seniat',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': this.id,
        'views': [(False, 'form')],
        'target': 'new',
    }

如何以新的API方式返回此值？

這是回溯：

有任何想法嗎？

如果您確實要使用新的API，請完整遷移代碼。 對於您的方法，應為：

@api.multi
def search_partner_seniat(self):
    """ Check vat of the partner and update iva rate
    """
    self.ensure_one()
    vat = self.vat.upper()
    res = {
        'name': _('The requested contributor does not exist'),
        'vat_subjected': False,
        'vat': vat,
        'wh_iva_agent': False,
        'wh_iva_rate': 0.0
    }

    if 'VE' in vat:
        vat = vat[2:]

    # assumption: both methods in new api style
    if self.env['res.partner'].check_vat_ve(vat):  # check_vat_ve() should be @api.model
        res = self.env['seniat.url']._dom_giver(vat)  # _dom_giver() should be @api.model
    self.write(res)

    return {
        'type': 'ir.actions.act_window',
        'res_model': 'search.info.partner.seniat',
        'view_mode': 'form',
        'view_type': 'form',
        'res_id': self.id,
        'views': [(False, 'form')],
        'target': 'new',
    }
