to accomplish this you would need to rewrite the orm.util.polymorphic_union
function to include these additional expressions within each SELECT under a
common label name, then override the part of AbstractConcreteBase which applies
the polymorphic_union in order to accomplish this.
These two
Folks I have this toy example I've sanitized.
class TableBase(AbstractConcreteBase, Base):
pass
class TableA(TableBase):
__tablename__ = "table_a"
__mapper_args__ = {
"polymorphic_identity": "A",
"concrete": True,
}
v0 = Column(Integer)
