unable to create migration file
abhimal opened this issue · 2 comments
hello, I have followed your django-on-docker series, but when I Deploy Django to AWS with Docker and Let's Encrypt I'm unable to create a migration file whenever I add new field in my django model and run docker-compose -f docker-compose.prod.yml exec web python manage.py makemigrations --noinput
unable to create migration file .

Note: I hide my aws-account-id and region. Image properties to use images from ECR, i also removed the db service (and related volume) since i'll use RDS rather than managing Postgres in a container.

Note: I remove migrate commands in the entrypoint.prod.sh script so they don't run on every container start or re-start. Instead, i can run them manually, after the containers spin up, like so:
docker-compose -f docker-compose.prod.yml exec web python manage.py makemigrations --noinput
docker-compose -f docker-compose.prod.yml exec web python manage.py migrate --noinput
Please help me. @jangia
Saw this only now. I'll take a look.
Oh, I see it's closed.
