当我执行Python manage.py makemigrations并迁移时，未检测到任何更改

I tried to make migration using python manage.py migrations tithe but nothing is detected. I have even changed my database to postgres, but nothing has changed. Even python manage.py migrate is not working. What could be the problem?

我试图使用python manage.py迁移tithe进行迁移但没有检测到任何东西。我甚至将我的数据库更改为postgres,但没有任何改变。即使是python manage.py migrate也无法正常工作。可能是什么问题呢?

@localhost church]$ python manage.py migrate tithe
Operations to perform:
  Apply all migrations: (none)

this is my model.py code

1 个解决方案

#1

the program works by removing abstract = Truein the class meta.after removing it when i run python manage.py makemigrations tithe and python manage.py migrate tithe it works wells

该程序的工作原理是删除抽象= True在类meta.after运行python manage.py makemigrations tithe和python manage.py迁移什么时删除它运行井
