I'm wondering how we can handle database migration in django while the site in production as while developing we stop the server then make changes in database then rerun the server I think it may be stupid question but I am learning by myself and can't figure it out thanks in advance.

migrate , which is responsible for applying and unapplying migrations. makemigrations , which is responsible for creating new migrations based on the changes you have made to your models.
When to run makemigrations. You'll want to run python manage.py makemigrations w henever you make a change to a model, even if it is updating the description on a field. Adding or updating functions inside of a model does not need a migration, but you can still run makemigrations just in case.
Deleting migration files means losing your history. This historical info is recorded in the django_migrations table in your database. if you delete migration files, you will get dependency errors. So Don't try to lose your history by deleting your migration files.
You can connect to the server using ssh and run commands to migrate without stopping the server and once you are done, you restart the server.
python manage.py makemigrations
and then
python manage.py migrate
and then restart the server.
for example: in case of nginx and gunicorn
sudo service gunicorn restart
sudo service nginx restart
