We are trying to build a full OGM for a Python/Flask based backend which uses Neo4j.
The problem I am running into is with the RelatedTo and RelatedFrom parts of Py2neo.ogm framework.
Naturally, if my graph has a structure like (a)-[:LINKS_TO]->(b) I would want OGM properties:
links_to = RelatedTo(b, "HAS")
linked_to = RelatedFrom(a, "HAS")
Note: I have used the objects a and b here not 'a' and 'b'. When I switch to using quotes it does not seem to retrieve the GraphObjects at all.
This causes Python to freak out with the circular dependencies since a is referencing b before it is defined.
I have not found a way to "forward declare" classes in Python like you can in some other languages.
This must be an extremely common situation in Py2neo, how are others solving it?
