Thanks, Jonathan. I must have read your earlier post a dozen times, and it
certainly pointed me in the right direction -- at least, enough to get my
query working.
I'm going to study your test a bit -- thanks for posting it.

Hi Mike,
I'm using your variant on the 'unique object' recipe (see previous
posting http://goo.gl/I1buRz) with some composite association proxies.
Recently, the data I've been working with introduced a duplicate in the

Ok, Mike. Thanks.
Ended up removing the trigger from the model and pushing that code to the
controller, so that foo updates the bar attribute after form data with
UserCourse objects is handled.

How would you recommend tackling these problems?

I'm almost certainly exposing my level of ignorance here, but does this
mean I could just replace
DBSession.configure(binds={DB1:db1_engine, DB2:db2_engine})
with
DBSession.configure(class_=MySession)
?
I suppose I could even use
DBSession = scoped_session(sessionmaker(class_=MySession,

Is this error the result of both association proxies using the same
attribute mapped collection ('interest_name')? Garbage collection during
the get_distance method or list comprehension?
I'd appreciate any suggestions -- thanks.

Hi, all. I've been trying to modify the example of a composite association
proxy

to fit my needs.
In the documentation example, there is a User object, a Keyword object, and

It took a few hours to wrap my head around your work and adapt it to my

I'm grabbing data from a Student Information System (SIS) about students and

What I've been doing so far is the following:

I'm not sure how I could do that because I'd want to set active to 0 only on
the students that are no longer going to school here.
Maybe merge isn't the right thing to do, or maybe I need to rethink my
algorithm. The bottom line is I need to know what records get added to the
local database
Thanks for your responses. I've been doing quite a bit of probing and I
think I have what I need now to get the job done. Sorry for the confusion,
I wasn't being very clear.
The problem with setting active to 0 after the fact stems from the fact that
