SQLAlchemy doesnt expect your class to have customizations going on
with __new__(). either fix your __new__() method to require only
the cls argument, or create a MapperExtension that provides the
create_instance() method, so that you create new instances yourself:
Hi Folk, I'm finding difficult implement this features of SA .
The example is: a simple table with a column type. I want to do a
secondary mapper based on the primary mapper with the only different in
the column type='something'
create table person(
name text,
type text);
class
I use hardly the column prefix, so my query are always aliased.
this obviously cause a lot of problem whith the order_by clause (that
NOT use the same aliases)
Is there some solution or mus wait for the new relase?
This is a tipical Example ...

you can only order by tables that you have added to the query
explicitly or via join(). you cant order by columns that are added
by eager

For this reason i've inserted explicit primaryjoin condition, and
