Hi there, I'm facing an issue with the use of AbstractConcreteBase class and a @declarred_attr returning a query_expression()
class A(AbstractConcreteBase, Base): @declared_attr def foo(cls): return query_expression() class B(A): ... class C(A): ... objects = db.session.query(A).options(with_expression(A.foo, my_expression )).all() B and C objects returned have the property foo but it is None The generated SQL query returns a value for the expression but the mapping seems to be not effective Am I doing something wrong ? -- SQLAlchemy - The Python SQL Toolkit and Object Relational Mapper http://www.sqlalchemy.org/ To post example code, please provide an MCVE: Minimal, Complete, and Verifiable Example.
