I have some 0.91 sqlalchemy code that I'm trying to get up to date.
For the most part, I've found where everything moved and am impressed
at how much better the SA integration is than my hackjob.
The one problem at the moment is that I have a few scheduled functions
that are throwing
InvalidRequestError: This Compiled object is not bound to any engine.
when called. The offending queries are from assign_mapper'd objects
and look like:
select([func.count('*')],self.c.tstamp > (now-tdelta)).execute()
Which is written using self.c because the same code operates on three
identically structured tables.
This code works fine when run using tg-admin shell and some queries
succeed, so it's only some of the queries that are unbound. So my
question is: what am I missing when it comes to binding an engine?
(I'm hoping someone can provide me with a quick answer before I have
to start reading source code.)
Regards,
Karl
