hm i had not run my tests for quite a while.. this seems recent thing.
lets see if i can dig anything of help... nothing much, one side
works, another not at all.
one of my set of inheritance tests (direct over sa, A-B) is ok.
the other one (over dbcook) fails completely, even for A-B
um yeah, actually this behavior is affecting all multi-level usage of
polymorphic_union. So, while polymorphic_union is quite obviously
(since nobody has noticed this pretty glaring issue) on the decline in
the 0.5 series, this is quite severe and ill try to have a look at it
today.

this ones big, i can handle it. the attached patch makes your case
work, but the problem represented here still makes itself apparent in
other ways and I havent strength tested this patch. you might want
to see if this patch works in all of your test cases.

this is still there:
File sqlalchemy/orm/mapper.py, line 168, in __init__
self.with_polymorphic[1] = self.with_polymorphic[1].alias()
TypeError: 'tuple' object does not support item assignment
also, related question: once there is A-B-C, concrete, how u'd get
some A by id?
and maybe related:
def query_by_id( klas, idname, oid, .):
q = session.query( klas).filter_by( **{idname: oid})
# filter by atype for concrete
m = class_mapper( klas)
concrete = bool( m.with_polymorphic[1] )
if concrete: q= q.filter( m.polymorphic_on ==
thats strange, i dont suppose you could send me how you're setting up
that polymorphic union

can i... maybe something like
table_A = Table( 'A', meta,
Column( 'name', String(length=200, ), ),
Column( 'db_id', primary_key= True, type_= Integer, ),
)
table_B = Table( 'B', meta,

okay, then i get this as answer to my other question - so concrete
polymorhism relations/get()/identity on top of it are blue_sky.
that's okay - just put a line about it in the docs.
dbcook is throwing warnings about it since long time.
