Tried to use the extension, but it results that it is not performing
correctly in 2.0.
The method of creating the uuid in code and later assigning to the server
is the one i have been using. Even though the probability is very reduced,
I have no way from code to recursively try for a new uuid i
There is for instance an uuid generating neo4j-extension from Stefan Armbruster
which might be worth checking out.
Otherwise you can also generate the uuid externally and use MERGE (n:User {
uuid : {uuid}}) ON CREATE SET n.name = {name} return n
Why do you want to assign an UUID to a relationsh
Currently I'm developing a social app for the iPhone with my computer as a
server, and have bumped into a couple of obstacles. One I'm particularly
trying to figure out is how assign an UUID to a node or relationship upon
creation and if it already exists try again with a different uuid. I want
