沒有這樣的列：django_content_type.name

Question

我在example.com的網站上部署了django-oscar的示例應用程序沙箱。 我想將其移至example.com:8000並在example.com網址上運行另一個項目。 我成功完成了第二部分，當你進入example.com時，你可以看到更新的django項目啟動並運行，但問題是，第一個django項目是django-oscar的沙箱，不會正確響應。

當您輸入example.com:8000時，您會看到當前的調試日志：

現在我用Google搜索了這個錯誤，但我沒有得到任何有價值的結果。

還有，當我跑

sudo python manage.py migrate

發生以下情況，我也找不到任何正確的解決方案：

更新1：我也在使用django 1.7.8。

更新2：我將我的Django版本更改為1.8.1，makemigrations和migrate命令工作正常。 然后我再次運行服務器，現在我在日志中收到此錯誤:(我也刪除了apache設置，因為它們無關緊要！）

Answer 1

我終於可以解決我的問題。 問題是我使用django 1.8來運行manage.py migrate並且該項目是在django 1.7.1下開發的，因此遷移打破了問題。

所以我做的是我再次安裝了django 1.8.1，運行了manage.py migrate contenttypes 0001 ，然后卸載了django 1.8.1，安裝了django 1.7.8並運行了manage.py runserver ，一切恢復正常，工作正常。

Answer 2

我遇到過同樣的問題。 在我的情況下，我使用Django 1.10來創建我的本地數據庫，但我需要使用舊的Django版本（1.7）進行一些測試，所以我刪除了我的本地數據庫並使用Django 1.7運行manage.py migrate然后錯誤消失了。

或者，當項目使用Django 1.10運行時，數據庫可以保留並移回項目，而不是刪除本地數據庫。
