IndexError：元组索引超出范围 - Odoo V8到V10 Odoo社区模块迁移

Question

考虑这个方法：

@api.multi 
def _dom_giver(self, vat): 
    """ Check and validates that the vat is a passport, 
    id or rif, to send information to SENIAT and returns the 
    partner info that provides. 
    """ 
    #if context is None: 
     #context = {} 

    url_obj = self.browse(self.search([]))[0] 
    url1 = url_obj.name + '%s' 
    url2 = url_obj.url_seniat + '%s' 
    vat = self._validate_rif(vat) 
    if vat: 
     return self._get_rif(vat, url1, url2) 
    else: 
     return False 

这是我从V8到V10迁移的方法，当我点击这个按钮：

@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): 
     res = self.env['seniat.url']._dom_giver(vat) 
    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', 
    } 

它调用以前的方法_dom_giver但是当我点击它，它抛出我：

IndexError: tuple index out of range 

的错误出现在这一行url_obj = self.browse(self.search([]))[0]，我已经检查了V10的社区，但似乎是确定的，我不知道这可能是，在v8这种方法是这样的：

def _dom_giver(self, cr, uid, vat, context=None): 
    """ Check and validates that the vat is a passport, 
    id or rif, to send information to SENIAT and returns the 
    partner info that provides. 
    """ 
    if context is None: 
     context = {} 

    url_obj = self.browse(cr, uid, self.search(cr, uid, []))[0] 
    url1 = url_obj.name + '%s' 
    url2 = url_obj.url_seniat + '%s' 
    vat = self._validate_rif(cr, uid, vat, context=None) 
    if vat: 
     return self._get_rif(cr, uid, vat, url1, url2, context=context) 
    else: 
     return False 

任何想法？

Answer 1

替换：

url_obj = self.browse(self.search([]))[0] 

由：

url_obj = self.search([], limit=1)
