How to reset migrations in Django 1.7

I would just do the following on both the environments (as long as the code is the same)

  1. Delete your migrations folder
  2. DELETE FROM django_migrations WHERE app = <your app name> . You could alternatively just truncate this table.
  3. python manage.py makemigrations
  4. python manage.py migrate --fake

After this all your changes should get detected across environments.


Run

python manage.py migrate your_app zero

This will drop all tables from your_app

If you want, since you said you want to start over, you can delete your migrations folder, or maybe rename the folder, create a new migrations folder and run

python manage.py makemigrations your_app
python manage.py migrate your_app

Just like south, you can always go back and forth...

# Go to the first migration
python manage.py migrate your_app 0001

# Go to the third migration
python manage.py migrate your_app 0003

So imagine that your 4th migration is a mess... you can always migrate to the 3rd, remove the 4th migration file and do it again.

Note:

This one of the reasons your models should be in different apps. Say you have 2 models : User and Note. It's a good practice to create 2 apps: users and notes so the migrations are independent from each other.

Try not use a single application for all your models


A minor variation on harshil's answer:

$ manage.py migrate --fake <appname> zero
$ rm -rf migrations
$ manage.py makemigrations <appname>
$ manage.py migrate --fake <appname>

This will ...

  • pretend to rollback all of your migrations without touching the actual tables in the app
  • remove your existing migration scripts for the app
  • create a new initial migration for the app
  • fake a migration to the initial migration for the app
