I've seen that relationship properties are not yet implemented in neo4django. The workaround exposed in this thread is to have a new node type for each relationship with a property.
I can't afford too much calculations so I don't want to use this technique. While reading the source code I've seen, as the docstring of the Relationship class, this : """Extend to add properties to relationships."""
My question is, how to do that ? Where to start to add at least one property ?
Thanks
Despite the docstring, this is still an open issue- the project's oldest, actually. There might be a way for you to pull it off by extending Relationship and BoundRelationship, but it won't be easy until I'm able to close that issue.
I would argue that this issue probably won't be a bottleneck using the project, since you can just give Neo4j more memory for the node store than the relationship store to account for it. YMMV of course.
I know it feels like a hack, though. If you really need custom relationship properties, the shortest path might be dropping down to the REST client level. To create relationships with properties, you could do something like
class Person(NodeModel):
name = StringProperty()
friends = Relationship('self', rel_type='friends_with')
pete = Person.objects.create(name='Pete')
dave = Person.objects.create(name='Dave')
# from the neo4j-rest-client [docs][2]
pete.node.relationships.create("friends_with", dave.node, since=123456789, introduced_at="Christmas party")
WDYT?
