you are not the first to have these particular issues, I am going to look into the docs today and see if I can break out more clearly the job of the unit of work, and what it does do/does not do, as the various emails ive gotten on this type of thing are clarifying for me some notions that were "implicit" in my own mind (which is why i like help with docs in general..)

the obj.delete() method itself, which comes from assign_mapper, is already an extension...the official way to delete an object is objectstore.get_session().delete(obj). so feel free to add your own delete() method that does what you want, and id be interested to see how you go about finding all the references to that object.

Thanks alot Michael for your detailed reply. I think most of my
confusions were due to some pre-convieved ideas I had regartding ORMs.
I wasn't aware of the whole concept of sessions and, probably because
of 'backref's, I had the misconception that sqlalchemy would do
everything.

Now that I understand a bit more the do's and dont's I am wondering if
there's any possibility of having extension points. This way I could
implement the cleanup of the references when the user issued an
obj.delete(). Do you think this can already be done with the current
API?


yah, thats exactly what it does, not like theres an entire section in the
docs on that or anything.....

I'm sorry for skiping that one :|
