I'm using declared_attr.cascading from sqlalchemy-1.0.0dev to declare a
foreign key on a subclass that also needs another separate foreign key

To let the Mapper know which column to join for the polymorphic
inheritance relationship, I'm trying to pass an inherit_condition argument.
Relevant code snippet can be seen here:
https://gist.github.com/anonymous/1b24768cb714fb9c7de7
this is fixed in 3a56c4f019052c5d and your example case now succeeds.
Importing this code generates this warning:
SAWarning: Implicitly combining column secinfo.id with column optinfo.id
under attribute 'id'. Please configure one or more attributes for these
same-named columns explicitly.
...and then fails with this error:
sqlalchemy.exc.ArgumentError: Mapper Mapper|OPTINFO|optinfo could not
assemble any primary key columns for mapped table 'Join object on
secinfo(23263120) and optinfo(19756496)'
How can I configure this correctly?
