Anyway, the Table object "neighbors_table" is not part of the locals() when the string expressions are evaluated. therefore just don't use string arguments for primaryjoin/secondaryjoin/secondary, use the expression directly (i.e. secondary=neighbors_table, primaryjoin=id==neighbors_table.c.neighbor_id). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
