There is a lot of them. But I think it have to be simple. Like a normal
query.
>From the docs I understand how to cache query with FromCache, how to cache
relationship with RelationshipCache,
but I don't find how to cache polymorphic relationships.

I might be wrong, but maybe you could also use eval if you don't know which
class at runtime.
i.e.
session.query(Person).with_polymorphic(eval(classString))
where classString is a string equal to the name of the class.

Then you can use session.query(Person).with_polymorphic('*') to mean
joining to the tables of all mapped subclasses. (Be aware that this can
become problematic if t
but I dont know on the time of query what the type of object it will be.

Hi Pavel,
You want: s.query(Person).with_polymorphic(Man).get(51)

Hello!
How can I cache query like this:
session.query(Person).get(51)
where 51 is id of Man
I can't access attribute age of Man without SELECT.
Models:
class Person(Base):
__tablename__ = 'person'
id = Column(Integer, primary_key=True)
name = Column(String(100), nullable=False)
