Hhmm. i don't believe in virtual beers, so maybe, treat you with this? http://www.giovannisample.com/media/mondo/Mondovision640.zip > and the latest is in a branch http://svn.sqlalchemy.org/sqlalchemy/ > branches/polymorphic_relations . i'll test how far it goes... quick test: This one fails some of the AB_all cases (the trunk passes them all - total 139). All failures are of same kind - the inheriting mapper (B) does not load some of it's references. i think there was similar error before and u did fix it then. see attachments (run "sa_ref_A_B_A_all.py eager generate_many failed_only" to get them all as sep.files) i'll check more on how A,B,C behaves. > so, the one thing i really cannot crack at all is how to make > polymorphic_union figure out the dupe "id" column in: > > > table_Employee.join(table_Engineer).select(table_Employee.c.atype > == 'Engineer'), > > since the embedded list of columns comes out only at compilation > time for the query. so i think i want to look into modifying > Select() to detect this internally and just raise an error. you > cant say "use_labels" on this particular query either because > polymorphic_union needs the real column names in order to determine > the names for the union. > > all you have to say is: > > select([table_Employee, table_Engineer.c.machine], > table_Employee.c.atype == 'Engineer', > from_obj=[table_Employee.join(table_Engineer)]), > > and it works, since you manually construct a column list that > doesnt contain a dupe. > u mean to put the explicit-column select() instead of polumuion's entry for Engineer? okay i'll try this approach... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
