[sqlalchemy] polymorphic_identity as an expression
hello!
is it possible to set the polymorphic_identity mapper param as an
expression?
example:
__mapper_args__ = {
polymorphic_identity: in_('employee', 'recruit')
}
thanks a lot,
richard.

polymorphic_identity, no. polymorphic_on, yes.work it from that end
instead (e.g. using CASE).
