推荐答案

您可以告诉Django进行特定迁移

You can tell Django to move to a specific migration

./manage.py migrate myapp 0005_migration_to_run

但是Django会每次迁移运行（或返回）您进行的迁移

But Django will run every migration up to (or back to) the migration you've chosen.

您可以尝试伪造 ，先迁移

You could try faking to the migration before

./manage.py migrate --fake myapp 0004_previous_migration
./manage.py migrate myapp 0005_migration_to_run

然后，您可能想要伪造您开始的迁移。

You might then want to fake to the migration you started at.
