升级到 django 1.7 后，我在管理页面中编辑模型时得到以下回溯（IE 单击单个模型的条目以访问其详细信息）

迁移后，应用程序和管理员似乎可以正常工作，直到我开始执行此操作。显然（？）我没有对事物的管理方面进行测试，所以我只是在尝试时才发现这一点。

知道需要做什么来纠正它吗？我是否有一些 1.6 中不支持的剩余旧模板，或者我是否未能更新某些内容以与新模板一起正常工作？

完整的追溯（希望我可以发布这个“折叠”！）

您可能得到了二次回溯。尝试直接在命令行上而不是在网络浏览器中获取主要的。尝试使用以下方法重现错误：

python manage.py runserver --traceback --nothreading --noreload

只有第一个选项非常重要。其他选项仅简化调试。

你的错误在课堂ErrorList上。UserList 类仅用于 Django 1.7，而不用于任何较旧的 Django，因为它在任何以前的 Django 中都不存在。

事实证明，这是由于 django-nested-inlines 的过时版本造成的。

调试的线索来自询问“这是什么 AdminErrorList？”，这导致“admin.py 中有什么？”，这导致“哇，这是什么嵌套行的东西，它是否符合 1.7”。

最近有一个关于 django-nested-inlines 的提交，它提到了与 AdminErrorList 相关的更新，这个更改解决了我的问题。
