Python 名称错误：全局名称'；cr和x27；未定义-从Odoov7迁移到Odoov10

我在OpenERP v7上有此向导：

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{}

我已成功安装此向导的源模块，但当我尝试实际运行此方法时，出现以下错误：

我知道这种调用

查询的方法在新的API上是不可行的，但是我如何在v10上替换它呢？它和v8不完全一样

有什么想法吗？
我用
self.env.cr
这样解决了它：

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{}

cr
应将光标固定在数据库上。你只是没有把它放在任何地方使用。您是否尝试过使用
\u cr
或
self.env.cr
？我不熟悉openerp，所以在黑暗中点击这里。嗨，是的，我用selv.env.cr解决了它。我要回答我自己的问题，谢谢
