django-migration-rollback 1.0.0

A simple Django app to be able to migrate back to a previous migration or to migrate back to a migration in a specific branch in a git repository or locally.

Django Migration Rollback

A Django package used to just make the python manage.py migrate a little easier for Django apps that commit their migrations and want a way to rollback to a previous migration without needing to check what the which one it is via python manage.py showmigrations or in the project's git repository.

Features

Able to set which branch in a git repository to rollback to using the custom command migraterollback or if you wish to just rollback to a previous migration only via migrateprevious. Note in order to use the rollback with a git repository's branch feature with git the project must have a .git file present.

Django migraterollback command

❯ python manage.py migraterollback polls feature/really-cool-branch
Attempting to go back to rollback polls to latest migration on branch feature/really-cool-branch
Operations to perform:
    Target specific migration: 0006_question5, from polls
Running migrations:
    Rendering model states...
DONE
    Unapplying polls.0007_question6...
OK

This command is used to migrate a Django app back to the migration found in a repository's branch (this will also migrate to that migration if behind).

• An app must be specified as the first argument after the command to indicate which app you wish to rollback.
• By default if no argument is specified after the app, the branch main will be used.
