Hi there,
I've been using zope.sqlalchemy's integration with SQLALchemy and it's
been working pretty well so far.
Today however I ran into a snag when using session.query(..).delete().
While a query immediately after the delete showed no more objects, in
the next transaction the objects
Hi
How can I have a foreign key reference between the models of two
different TurboGears projects?
I am using sqlalchemy.

the MySQL has gone away error usually corresponds to a connection
thats been held open without activity for 8 hours. if thats not the
case here, either the MySQL client config has the timeout turned way
down or something is broken at the network level.

I've got a somewhat oddball situation, and I'm hoping for some pointers
to the right sqlalchemy features to handle this. Or, failing that,
hints as to the places I'm going to need to write code to compensate
for the weirdness I have to deal with.
The situation is that I get periodic copies of a
Maybe I did something wrong so loosely following the example

which I realize is a bit old now. I was able to get my basic mappers
setup and working.
class NodeLoader(MapperExtension):
def create_instance(self, mapper, selectcontext, row, class_):
Unfortunately, it still gives me an error.

After pondering this for awhile, I think the easiest solution would be
to do this:
1. Have it connect to a hardware vip that manages failovers etc to my
2 servers.
2. Have 1 dedicated pool, when the connect occurs on the vip, the vip
will evenly distribute.
3. Set the pool to have idle recycle

also, I wonder how the way you were doing it before, with composite,
was actually working out ? It wasn't intended to hold half of a
primary key like that which is probably why I warned against it, but
if its working for you, there's no reason not to use it.
I.e. with declarative just put

Can you elaborate a bit on how to do each of the thing you said -
metadata sharing between 2 separate Turbogears projects and placing
the actual column in the ForeignKey constructor, instead of string
'table.column.id'.
I read your earlier discussion
I got a solution. Thanks to Michael. Here is what he suggested.

You use the Column object:
from myproject.model import sometable
someothertable = Table('someothertable', metadata, Column('foobar',
Integer, ForeignKey(sometable.c.foobar))
as you can see the common theme in both cases
