django - 迁移和模型转换的问题
django - trouble with migrations and modeltranslations
我正在尝试将我的应用程序从 Django v1.6.11 升级到 v1.7.8。我正在关注 instructions to upgrade from South 但一次又一次地遇到同样的错误。更准确地说：

在我看来，这是一个 django-modeltranslation 问题。我在他们的网站上检查了 dependencies，我使用的是正确的设置：django 1.7.11，python 2.7.5，django-modeltranslation 0.8.

更新：根据 dukeofweatherby 的建议，我从 urls.py 中删除了对 admin.autodiscover() 的调用。无论如何，在这之后我仍然得到同样的错误。
更新 2：from translation import * 在导入 TranslationAdmin 之前解决了问题
正好遇到这个问题，我可以通过删除
来解决它
admin.autodiscover()
Django 1.7 automatically discovers 新应用程序加载功能中的管理文件，我猜这会扰乱加载顺序。
请务必阅读文档并在 django.contrib.admin 之前注册 modeltranslation。这解决了我的问题。

希望对您有所帮助。

更新：根据 dukeofweatherby 的建议，我从 urls.py 中删除了对 admin.autodiscover() 的调用。无论如何，在这之后我仍然得到同样的错误。
更新 2：from translation import * 在导入 TranslationAdmin 之前解决了问题
正好遇到这个问题，我可以通过删除
来解决它admin.autodiscover()
Django 1.7 automatically discovers 新应用程序加载功能中的管理文件，我猜这会扰乱加载顺序。
请务必阅读文档并在 django.contrib.admin 之前注册 modeltranslation。这解决了我的问题。
