Sorry I actually meant to say "alembic revision". It is the command to
create a new migration script in the source tree based on the template.
I always get that command name wrong.
The "no handlers found" message is just pointless spew from the Python
logging subsystem, not an actual error. However the "alembic upgrade"
and "downgrade" commands won't work with Beaker, due to the hackery
needed to glue Alembic into all the existing database code which is
inherited from TurboGears.
The normal way to upgrade/downgrade the database schema on a Beaker
installation is using beaker-init (to upgrade) or
beaker-init --downgrade=<version> (to downgrade).
If you're running from a git checkout with a database configured in
dev.cfg, you can just do something like:
PYTHONPATH=../Common:. python bkr/server/tools/init.py --debug
Thanks for the description
something flukey here for me.
I have auto generated 3dd091c46d50 as head using alembic revision, but
db version stays at f18df089261. Using methods described above,
including beaker-init (--downgrade)have no affect on the db version.
I can interact with the db with the alembic stamp command but only to
maniuplate the version_number. Other db changes do not seem to be
