Hi
do you have one node for both direction or two nodes, one by direction ? As far
as I know, the current dijkstra implementation only allow single node. Maybe
this is the problem but im not the specialist in this matter.

Subject: [Cartoweb-users] pb dijkstra module
Hi all,
I am trying to install dijkstra module on postgreSQL 8.0 with debian ;
after the execution of assign_vertex_id (which works), I have an error msg
launching the create_graph function :
ERREUR: une clé dupliquée rompt la contrainte unique
«route500_44_edges_source_key»
CONTEXT: instruction SQL «INSERT INTO route500_44_edges (id, source, target)
VALUES (944, '671', '703')»
I don't know where this duplicated key ("clé dupliquée") can come from.
Can anyone help?
Thanks
G.
