Hi Mike, I have having issues letting a subclass load a parent's relationship that configured lazy="joined".
Let's say Engineer is a subclass of Person, and Person stores "company_id" and has a relationship called "company" that is lazy="joined". Although I don't have a minimal reproducible example now, but in my setup, let's say: engineer = session.query(Engineer).get(1) # emits 1 query engineer.company # emits another query I suspect that the subclass does not respect parent class' relationship lazy/eager loading options. Also I bump into this issue when identity map remembers the id's polymorphic type. Then when I query on the base class, it emits the the subclass query and does not load the parent class' relationship with eager load options, which is the problem I mentioned. engineer = session.query(Engineer).get(1) session.commit() person = session.query(Person).get(1) # emits 1 query person.company # emits another query Is this by design? If so, is there any way to make it respect parent class' relationship "lazy" option? I am not 100% certain this is reproducible in a simple example. There may be problems in my setup that would cause this. Please let me know if this is the case.
