py2neo relationship issue

[Frederic]

Hi,

I have the following issue, i want to graph routes with relationships from devices to devices depending on the destination.

So i've got a loop looking like this :

for i in range(len(Super)):

    

    A=Node(tt, name=Super[i][1])

    graph.merge(A)

    B=Node(uu, name=dd)

    graph.merge(B)

    

    graph.create(Relationship(A, "Route", B,dst=Super[i][0]))

But when i do this there is only one route between A and B (file : notalltheroutes)

- if i do a create for node B like this :

for i in range(len(Super)):

    

    A=Node(tt, name=Super[i][1])

    graph.merge(A)

    B=Node(uu, name=dd)

    graph.create(B)

    

    graph.create(Relationship(A, "Route", B,dst=Super[i][0])

I've got all the routes but destination nodes are duplicated (file : alltheroutes)

How to do to have all the routes without duplicate nodes ?

Thanks.
