从Django 1.3升级到1.5.5应用程序单元测试失败，AttributeError:PositionForm对象没有属性'；已清除的数据

我正在从Django 1.3升级到1.5.5。以前所有的测试都成功了，但现在这个失败了，我不知道为什么。我已经包括了堆栈跟踪和出现在堆栈跟踪中的函数。有许多用于调试的日志语句，因此请注意

在保存表单集之前，需要对其进行验证

            fset = FormSet(self.data, self.files, prefix=self._get_formset_prefix(key),
                           instance=instance)
            logger.info("BEFORE PSAVE FSET SAVE")
            if fset.is_valid():
                fset.save()
            else:
                // display form errors

---

当您知道阻止保存表单集的错误时，您可以调整

profile\u post\u数据

以确保其有效。

如果在

fset.save（）之前添加
fset.is\u valid（）
，会发生什么？
