使用--fake后，如何重做django 1.8上的迁移 [英] How to redo a migration on django 1.8 after using --fake

问题描述

我的迁移出了问题，我向模型添加了一个新的datetime域，然后我使用makemigrations和迁移。

Something went wrong on my migrations, I added a new datetimefield to a model then I used makemigrations and migrate.

python manage.py makemigrations
python manage.py migrate

但是之后，迁移得到了一个表已存在错误。我想我可以伪造这些迁移并重新开始，所以我做了一个

But after this the migrate got an "table already exists error". I supposed I could fake the migrations and start over, so I did

python manage.py makemigrations --fake core

Operations to perform:
  Apply all migrations: core
Running migrations:
  Rendering model states... DONE
  Applying core.0001_initial... FAKED
  Applying core.0002_auto_20150525_1331... FAKED
  Applying core.0003_auto_20150525_1348... FAKED
  Applying core.0004_processo_data_atualizacao... FAKED

但是我刚刚创建的新迁移也是伪造的（当然！）。

but the new migrate that I've just created was faked too (of course!).

在这样做之后，正确的方法可以重做迁移（在这种情况下是core.0004）？

How is the proper way to redo a migration (in this case the core.0004) after doing this?

推荐答案

状态到0003与 - 假的/ / code>（假设0003是你真正应用的最后一个迁移）：

You should first set your current state to 0003 with --fake (assuming 0003 is the last migration you really have applied):

python manage.py migrate --fake core 0003

然后继续像往常一样：

python manage.py migrate core
