I want to query this structure:
A -> B
B -> C
B -> D
what's the syntax to do this with the Load interface, the documentation is not very clear on this (http://docs.sqlalchemy.org/en/latest/orm/loading_relationships.html#sqlalchemy.orm.joinedload). All I see is how to do:
A -> B
B -> C
C -> D
Given the query:
query(A).options(joinedload(A.b).joinedload(B.c))
How do I go backward in the chain to specify the second relationship on B (B.d)?
