all tests pass with rev 2267 of that branch. try that rev
specifically, since i want to take whats there and do another pass.
im trying to get it so that the entire science of "parent table,
child table, polymorphic selectables, primary join -> polymorphic
joins -> determine direction/lazy clause/eager clause/synchronize
FKs" is super-well-nailed down.

Hhmm. i don't believe in virtual beers, so maybe, treat you with this?

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...
