類型錯誤：不能連接「STR」和「功能」的對象 - Odoo V10社區

Question

我有這個功能，我是從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', 
    } 

我怎樣才能回到這個在新的API時尚？

這是回溯：

任何想法？

如果您確實想使用新API，請將代碼遷移完成。對於你的方法應該是：

@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', 
    }
