I just had a major realization...stared at the code for a few minutes (for
the 100th time) and realized this probably happens because I pass in a
string when I create the object, and then if I access it before it saves to
the DB it never gets parsed. That explains everything. I can't believe it
Hello,
I've had this "ghost" issue for about half a year now, every now and then.
Essentially, I have a model with a DATERANGE column (to match my PostgreSQL
daterange column). "Most" of the time this works out well. However,
sometimes, seemingly depending on the exact code path (or something
I have some big ideas for the baked concept which may or may not
impact this area as well. But they are only ideas for now, I have
many explicit SQLAlchemy tasks that I have to get done before I can
try to explore that stuff.

Hoi Mike,
You're right, we should probably measure it first. You state that the
simple joins and filters are probably cheap which I don't doubt. We also do
correlated subqueries and stuff. Actually, we also use the baking mechanism
to cache some of our own processing which goes into the

for SELECTING from PG's special functions, see if you can find a
solution in the many recipes at
https://bitbucket.org/zzzeek/sqlalchemy/issues/3566/figure-out-how-to-support-all-of-pgs
for now.
I haven't looked closely at your specific problem yet but it seems to
correspond with those.

Hi all!
Is there support in Alembic for anything like the "redo" feature present in
Ruby on Rails' Active Record Migrations tool? I often find myself running
an "upgrade", followed by a "downgrade" and then finally another upgrade,
in order to be sure the migration's rollback function is
Hi everyone,
I have a database of some `items` which have a range (tsarange =>
DateTimeRange) column that usually ranges in intervals of a bunch of
seconds and I basically want to create an availability statistics of those
items (based on their `lower(Item.range)`) for some period (month/day)
