I use declarative to define database scheme, and binds parameter to session constructed from several metadata tables lists. And I have a problem with inherited models, where table is represented as Join object: get_bind() method doesn't find an engine. A quick-n-dirty solution I use is:
class Session(orm.session.Session): def get_bind(self, mapper, clause=None): from sqlalchemy.orm.util import _class_to_mapper if mapper is not None and clause is None: c_mapper = _class_to_mapper(mapper) if hasattr(c_mapper, 'mapped_table'): clause = mapper.mapped_table return orm.session.Session.get_bind(self, mapper, clause) Is it a bug in SQLAlchemy or I use it inapropriately? What is correct solution? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
