Answer 1

rm -f tmp.db db.sqlite3 rm -r my-app/migrations python manage.py makemigrations python manage.py migrate

Removes the database.
Removes the migrations from your app.
Re-runs the migrations. Note: you could also do: python manage.py makemigrations my-app
Migrate changes.

Answer 2

1. Delete the sqlite database file (often db.sqlite3) in your django project folder (or wherever you placed it)
2. Delete everything except __init__.py file from migration folder in all django apps (eg: rm */migrations/0*.py)
3. Make changes in your models (models.py).
4. Run the command python manage.py makemigrations or python3 manage.py makemigrations
5. Then run the command python manage.py migrate.

That's all.

If your changes to the models are not detected by makemigrations command, please check this answer

Answer 3

To do everything in one go, run all below commands in a shell script (Linux flavors) or in a batch file (Windows). and run that script where your manage.py exists:

find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
find . -path "*/migrations/*.pyc"  -delete
find . -path "*.sqlite3"  -delete
python manage.py makemigrations
python manage.py migrate
python manage.py migrate
python manage.py shell -c "from django.contrib.auth.models import User; User.objects.create_superuser('admin', 'admin@example.com', 'adminpass')"

I prefer them running by copy-pasting directly in one go. make sure to change superuser credentials.

Note- This will DELETE all databases and their corresponding migrations

Answer 4

You can just delete your sqlite file.

Regarding your question, you should use Django migration system to do database changes for you project using makemigrations and migrate commands
