Hello,
What is the correct way to use remote_side & single_parent relation
parameters under Declarative Base?
I'm trying to create an Adjacency List Relationship as suggested in
the docs, but I am not sure how to do this with Declarative Base.
I tried:
children = relation("Node", backref=backref("parent",
remote_side="nodes.id"))
But got:
InvalidRequestError: When compiling mapper Mapper|Node|nodes,
expression 'nodes.id' failed to locate a name ("name 'nodes' is not
defined"). If this is a class name, consider adding this relation() to
the <class 'db.Node'> class after both dependent classes have been
defined.
Thank you,
:)
