Re: [Neo4j] Traversing by Relationship property

Thanks Mattias and Michael for your answers!

I tried it with the following request for relationship property "to".


curl -X POST -H Accept:application/json -H Content-Type:application/json -d
'{  "order" : "depth first",  "uniqueness" : "node", "return filter" : {
"language" : "javascript", "body" : "position.length() > 0 &&
position.lastRelationship().getProperty('to',0) == 1" }, "max depth" : 1 }'
http://localhost:7474/db/data/node/40/traverse/node

All my relationships have the property "to" but i got  an exception that
"to"is not defined:
