Hi, I've done a mapping of a (not typical) tree structure. It's not completed yet, but the work in progress can be seen here: http://wojciechmalinowski.com/tree.zip
The idea was to make the model as simple as possible and do all the work in the mapper. The model should have only a few properties that can also be mapped by another tree structure (i.e. nested sets). I also wanted to make it as generic as possible so I can use it for different classes in my projects. I have a few questions now: 1) How to use SQLAlchemy extensions to create the special parent property that is now created using monkey-patching of a class? Is it possible? 2) How to use the technique shown in examples/derived_attributes/attributes.py to be able to filter other queries by node.all_children_with_self etc. 3) What other things can be made better here? 4) When I finish this example I can publish it in public domain. Can it be included in SQLAlchemy examples then?
