Not sure if this matters, but the model doesn't have an autoincrement

They both have to be subqueries because they can have where-statements.
If select_from() is the normal way than I have to live with these
additional select-from-constructions.
Do you have/know some example of how to use from_statement()?
Because I tried it with from_statement() but it doesn't
Thanks Jonathan, Alembic has been on my to-check-out list for a while.
Does anyone here use it for test db population?
I'm honestly not seeing the big advantage of populating from json files,
but I suppose there must be some. At any rate I have them from a previous
project the same client has

I have a module I import which has some table defs and

If the module is ran directly, it executes a create_all() to build a new db.

I don't , but should. I've just used database dumps and a homebrew system,
because tools like this didn't exist when I first needed them.

which you will eventually need in your new Django-favoring environment.

The Bundle option sounds perfect, there is really no need for the other
attrs to be None, i was just trying to explain the idea. Is there a nightly
avaliable of 0.9 that I can grab that has a partially working version of

you need to pass a Python callable function (def or lambda, typically) to
event.listen, which
it will call when the event occurs. right now you're just running the
execute() before the listen()
is even called:
event.listen(table, after_create, lambda *args:
trg.execute(bind=engine))
