Hi,
I have a large graph and I am trying to extract the list of edges that
correspond to some relationship "foo", node A -> node B.
I cannot figure out how to do this. I have tried using a traversal
class, but I am not having any luck.
neo = NeoService("the path")
class Follow(neo4j.Traversal):
types = [
neo4j.Outgoing.follows
]
order = neo4j.DEPTH_FIRST
stop = neo4j.STOP_AT_END_OF_GRAPH
def isReturnable(self, position):
return (not position.is_start
and position.last_relationship.type == 'follows')
for friend_node in Friends(node):
...
but this seems to only get the other end of the relationship, not both
ends. If I wrap this in a for loop "for node in neo.node" I get a huge
number of nodes, way more than are in the graph.
Even if I write an isStopNode function to mimick STOP_AT_DEPTH_ONE,
the script keeps going and I end up with millions of nodes in the
edgelist, when there are only 1000.
TIA,
Ryan
