nope, options(eagerload('a'), eagerload('a.b')) works just fine, have
tested it here to verify
You're quite correct.. Sorry for the noise. I had tried it a while
back and it didn't work yet. But in between now and then, it has
magically been implemented by you!
Thanks

Hi Paul,
Could this be one of those situations where MSSQL returns multiple result
sets? If the select for @@identity / @scope_identity() generates another
result set, MSSQL want a full fetch on the previous fetch before issuing a
new one. Fix would be client-side cursors for adodbapi, pyodbc
Hi there,
I'm trying to make a small (open source) inventory tracking system
with TurboGears and SQLAlchemy, and I have a little problem with how I
should implement the database part.
I think the best idea would be to have different sequences for each
type of item tracked, so spork number 543
FYI, specifying module=pyodbc didn't seem to help wrt the
ConcurrentModificationError. Didn't have very much time, had a (very)
quick look at the code in mssql.py, and at first sight, it would seem
that sane_rowcount is a global variable that is only set in the
use_pyodbc() (resp.
Random question for the list, and an idea. I have an application I am
working on that needs to be able to dynamically bind its metadata to
an engine based upon configuration. Logically, it seems I should use
`DynamicMetaData` and just call metadata.connect(engine) after I have
loaded my
Er well the whole point of DynamicMetaData was to replace the old
ProxyEngine, which was intended to emulate SQLObject's i dont know
what its called object which is what TG was using for thread-local
context.
Also, it doesnt entirely make sense that the threadlocal engine
strategy would
Yeah, disregard this, I found an easier way that doesn't fight SA.
For the record, the use case is a polymorphic collection with the occasional
exception. Exceptions were one-offs for which I didn't want to provide
derived mappers because they were well, rare one-offs. Those exceptions were
to be
use a composite primary key - just mark each column with
'primary_key=True'.

What's the use of exposing the identity map if you don't want people to
