Changing the default value of a field in django models, can't run migrations
So here's what happened, i am designing a website for my college and the user model has an integer field named "year". I added this field after i migrated once with the " AbstractUser " model. I run "makemigrations" again and it asks me to set a default value for year as it is a not null field. I mistakenly put "undefined" as the default in an Integer Field, and it gave me an error. so i changed the default as 1 in the models file and run makemigrations again. It worked, but when i run python manage.py migrate, it gave me the same error again: ValueError: Field 'year' expected a number but got 'undefined'. I don't understand what to do now... -

How to setup calm antivirus in k8s environment and interact from a django app pod?
I am using django-clamd (https://github.com/vstoykov/django-clamd) inside my django app. The scanning works fine on my local system while uploading files and virus containing files are detected.

How to run makemigrations for dockerized django app
I have been trying to setup a django app using this guide: https://testdriven.io/blog/dockerizing-django-with-postgres-gunicorn-and-nginx/ And it was a great resource to get everything up and running. However i have problem now when it comes to migrations. Say i add a model, add data into my db, and later i change the model. Now i can run makemigrations using the exec method on the container, but when i shut down my migrations are not stored in my local files i save to my git project, instead they are lost as i spin down the container. Does anyone know how to solve this, how do you makemigrations is such a setup where you run two dockerized django/postgres dev/prod environments?
