u mean a plain mapper without polymorphism, then above
query().with_poly? that seem to work.
but it still needs .filter(
discriminator==identity) for a get()-like op to work.
and in this case each query() will also needs the .with_poly(..)
stuff, so whole automatics (specifying things once) gets lost.
ah, forget it. i dont need concrete without working relations, just
played with the tests.
if u decide one day to finish this concrete stuff and need coverage of
fullblown combinations of A-B-C + all-possible-references, yell.
it's in dbcook/tests/test_ABC_inh_ref_all.py
the loss of synchron between the polymorphic_on and the
with_polymorphic[1] if alias'ed, may be a problem one day for
someone, but it's up to you.
