According to the alembic documentation, if I want to get the migrations history, I just need to do:
from alembic import command
from alembic.config import Config
alembic_cfg = Config("./alembic.ini")
command.history(alembic_cfg)
And I should be able to see the history, but it's actually returning null, even though when I run in the terminal: alembic history, displays correctly. I also tried to do os.system('alembic history'), but also returns null. Any idea how to fix this?
