python - 类型错误 : _get_loc_req() takes at least 3 arguments (1 given) - Odoo v8 to Odoo v10 community

Question

我有这个方法:

@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

每次我单击调用此函数的按钮时，它都会向我抛出以下错误:

正如我所说，我正在将一些模块从 v8 迁移到 v10 社区，我是否也应该更改参数？除了添加正确的装饰器之外？

装饰器@api.multi是我添加的，因为这个方法对记录进行操作，但也许它是不正确的？

Answer 1

按钮方法应如下所示:

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

使用新 API 不再需要“手动”处理数据库游标、记录 ID、用户 ID 和上下文。

使用旧的 API，你的方法也应该失败，或者上下文被 id 填充。它应该看起来像:

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

您刚刚错过了 ids。
