How to undo migration in Django

django_undo_migration.md

Let say you have migrations like this

project/apps/accounts/migrations
├── 0001_initial.py
├── 0002_historicalprofile_historicaluser.py
├── 0003_auto_20190807_1559.py
├── 0004_auto_20190811_1013.py

and currently you are in 0004_auto_20190811_1013.py migrations. and you want to undo migration or back to previous migration which is 0003_auto_20190807_1559.py

Use this command:

$ python manage.py migration accounts 0003

Note: accounts is the django app

You will see the output like:

Operations to perform:
  Target specific migration: 0003_auto_20190807_1559, from accounts
Running migrations:
  Rendering model states... DONE
  Unapplying accounts.0004_auto_20190811_1013... OK

Your django database now in 0003_auto_20190807_1559.py migrations.

Whats next?

Remove your 0004_auto_20190811_1013.py file. and you can start make new migrations.

Small note, if you want to reverse all migrations to the app (e.g. when you want to remove app) you can run python manage.py migrate accounts zero and start from scratch.

CommandError: No installed app with label 'accounts'.
