由于更改了models里面的org这一块,进行makemigration的时候出现
we can't do that (the database needs something to populate existing rows). Please select a fix:
1) Provide a one-off default now (will be set on all existing rows)
2) Quit, and let me add a default in models.py
然后手贱删除了migrations里面的文件,出现了错误,请问bobby老师有没有解救的办法
