尝试打开具有多个属性的产品时出现 Odoo 8 错误

Question

我们的 Odoo 是版本 8，运行 Ubuntu。

当我尝试打开具有多个属性（颜色、尺寸）的产品时，出现 KeyError: 57。其他简单的产品都可以。

知道是什么导致了这个问题吗？

这里是完整的回溯：

我遇到了和你的日志一样的错误，但我不知道你的代码细节。您应该检查字段类型。

在我的例子中，我使用了字段函数。

我被误认为如下：

rec = obj.browse(cr,...)
result = {}
# result[id] = val     # wrong
result[rec.id] = val   # correct

希望对您有所帮助..
