I want to use alembic revision --autogenerate
with my own model classes. Because of that I need to import them in myproject/alembic/env.py
as described in the docs. But this doesn't work even if I tried a lot of variations.
I am not sure in which context (don't know if this is the correct word) does alembic run the env.py
. Maybe that causes some errors.
This is the directory and file structure I use.
myproject/
common/
__init__.py
model.py
alembic/
env.py
The error is kind of that
from .common import model
SystemError: Parent module '' not loaded, cannot perform relative import
myproject
itself is just a repository/working directory. It is not installed into the system (with pip3
, apt-get
, easyinstall
or anything else).
