类型错误：_get_loc_req（）至少需要3个参数（1给出） - Odoo的V8 Odoo V10社区

Question

我有这样的方法：

@api.multi 
def _get_loc_req(self, cr, uid, context=None): 
    """Get if a field is required or not by a Localization 
    @param uid: Integer value of the user 
    """ 
    context = context or {} 
    res = True 
    ru_brw = self.pool.get('res.users').browse(
     cr, uid, uid, context=context) 
    rc_obj = self.pool.get('res.company') 
    rc_brw = rc_obj.browse(cr, uid, ru_brw.company_id.id, context=context) 

    if rc_brw.country_id and rc_brw.country_id.code == 'VE' and \ 
      rc_brw.printer_fiscal: 
     res = False 
    return res 

每次我点击它要求该功能的按钮，它抛出我这个：

正如我所说，我将一些模块从v8迁移到v10社区，我是否也应该改变参数？除了添加正确的装饰器？

装饰者@api.multi是我添加的，因为这种方法在记录上操作，但也许这是不正确的？

Answer 1

按钮的方法应该是这样的：

@api.multi 
def my_method(self): 
    # my logic 
    return True 

没有必要用新的API来处理数据库游标，记录ID，用户ID和“手动”上下文了。

对于旧的API，您的方法应该也失败了，或者上下文中填入了id。它应该看起来像：

def _get_loc_req(self, cr, uid, ids, context=None): 

您刚才错过了ids。
