具有讽刺意味的是，我正在获取更改的对象，以便我可以检查它们的强制性字段已设置。不幸的是，当缺少必需的外键式关系时，我甚至无法获得已更改对象的列表。

The ironic thing is that I'm getting the changed objects so that I can check their mandatory fields are set.  Unfortunately, when mandatory foreign-key-style relationships are missing, I can't even get the list of changed objects.

任何人？
