Hi, I'm having some problems when combining SA, assign_mapper and the identity framework.
I moved from using mapper to use assign_mapper when I couldn't figure out how to use the relations I've created in my models (as described here: http://groups.google.com/group/sqlalchemy/browse_thread/thread/9dc4bcecefd17d23). After changing model.py, I get the following error for all requests to the application: Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/cherrypy/ _cphttptools.py", line 103, in _run applyFilters('before_main') File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/CherryPy-2.2.1-py2.5.egg/cherrypy/filters/ __init__.py", line 151, in applyFilters method() File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/TurboGears-1.0.4b1-py2.5.egg/turbogears/visit/ api.py", line 148, in before_main visit = _manager.new_visit_with_key(visit_key) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/TurboGears-1.0.4b1-py2.5.egg/turbogears/visit/ savisit.py", line 48, in new_visit_with_key session.save(visit) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/SQLAlchemy-0.3.10-py2.5.egg/sqlalchemy/orm/ session.py", line 417, in save self._save_impl(object, entity_name=entity_name) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/SQLAlchemy-0.3.10-py2.5.egg/sqlalchemy/orm/ session.py", line 590, in _save_impl self._register_pending(object) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/SQLAlchemy-0.3.10-py2.5.egg/sqlalchemy/orm/ session.py", line 600, in _register_pending self._attach(obj) File "/Library/Frameworks/Python.framework/Versions/2.5/lib/ python2.5/site-packages/SQLAlchemy-0.3.10-py2.5.egg/sqlalchemy/orm/ session.py", line 619, in _attach (repr(obj), old, id(self))) InvalidRequestError: Object '<tnf.model.Visit object at 0x2430650>' is already attached to session '37947088' (this is '37947024') So it seems that when you're using assign_mapper, you must use the "visit.save()" form rather than "session.save(visit)". Is that true? I'd really appreciate some help in resolving the above error, or failing that, advice on how I can use my object relations without resorting to assign_mapper (I'm sure it must be possible...).
