Import data to alembic migrations

[Ilya Demidov]

Hi!

I have some problem. I need to add new field in table and populate it by some default data. I can not hardcode it because it different in debug and production enviroment. I want to store data in some "config file". The problem is migration does not see my modules.

├───alembic │
    ├───versions │ 
        ├───first_migration.py │
        ├───second_migration.py │

    ├─── migration_data.py

If I import from alembic. migration_data  import SOME_DATA it throws import error while migrating. 

Any good pratice, how can I store migration data? Thanks for advices.

yes, one particular approach to this issue is discussed here: https://alembic.sqlalchemy.org/en/latest/front.html#installation   start with that if nothing else is working (There are many ways to do this).
