hi,
I am not sur to understand "one node for one direction", but my data should be
in a correct format (well, I hope so!); they come from a shapefile from the
"route500" network, made by the IGN, and I have already installed the dijkstra
module on this type of data, without encountering this problem.
Can ou tell me more?
thanks a lot

Oliver Christen <[EMAIL PROTECTED]> a écrit : 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.
regards
Oliver

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.
