You are right Michael, in my alembic/env.py I had a line:
sys.path.append(os.path.abspath(os.path.join(os.path.dirname(__file__), '..'
)))
I replaced it with
sys.path.append(os.path.abspath(os.path.dirname(__file__)))
Is there any better or let's more conventional way of setting this up?
And it works now, if I run the script from my root directory, that contains
my_app and alembic directories. I was confused, because other commands
would run without issues.
Thanks a lot!
