依賴引用時，在Django

我dooing一個項目中，當我嘗試在Django遷移遷移不存在的父節點的錯誤，錯誤來依賴引用時，在Django

Traceback (most recent call last):

我理解的問題，但無法解決它。

我刪除了所有.pyc文件和遷移文件夾。

我也刪除了數據庫，但這個問題仍然存在。我如何擺脫這個錯誤。在此先感謝。

從應用程序中刪除migrations文件夾，也刪除數據庫並再次創建數據庫。然後嘗試：

1）蟒蛇manage.py makemigrations
2）Python的manage.py遷移

注意任何人閱讀本：不，從來沒有從任何應用程序「刪除文件夾遷移」。這將使用已經應用了先前的遷移的您的應用程序對任何項目的任何實例進行擰緊... –
