NameError：全局名稱「CR」沒有定義 - 從遷移到Odoov7 Odoov10

Question

我對OpenERP的V7此嚮導：

class UpdateInfoPartner(models.TransientModel): 
_name = 'update.info.partner' 

def update_info(self): 

    context = dict(self._context or {}) 
    seniat_url_obj = self.pool.get('seniat.url') 
    cr.execute('''SELECT id FROM res_partner WHERE vat ilike 'VE%';''') 
    record = cr.fetchall() 
    pids = [item[0] for item in record] 
    seniat_url_obj.connect_seniat(pids, all_rif=True) 
    return{} 

我已經成功地安裝從那裏此嚮導來自模塊，但當我嘗試實際運行這個方法，我有這樣的錯誤：

NameError: global name 'cr' is not defined 

我知道這個方法來調用queries是在新的API obslete，但我怎麼能代替這個在V10？它不完全像v8

任何想法？

Answer 1

我self.env.cr這樣的解決了這個問題：

class UpdateInfoPartner(models.TransientModel): 
    _name = 'update.info.partner' 

def update_info(self): 

    context = dict(self._context or {}) 
    seniat_url_obj = self.pool.get('seniat.url') 
    self.env.cr.execute('''SELECT id FROM res_partner WHERE vat ilike 'VE%';''') 
    record = self.env.cr.fetchall() 
    pids = [item[0] for item in record] 
    seniat_url_obj.connect_seniat(pids, all_rif=True) 
    return{}
