Re: [Neo4j] Gremlin - how to flatten a tree, and sort

hi again I suspect I'm missing something small, but when I run the following in the webadmin console, I don't get any output? m = [:]; g.v(162).in('R_PartOf').loop(1){m.put(it.object, it.loops); true}.cap.next().sort{a, b -> a.value <=> b.value}.keySet >> [] (m is empty too...) Thanks for the

Re: [Neo4j] Property loading in Neo4J 1.4

Properties on nodes/relationships are stored as a non-indexed linked list on disk so if you're accessing one property on a node/relationship neo4j has to load that chain (i.e. all properties, not necessarily their values though) for that node/relationship if it hasn't already done that (i.e. if its

[Neo4j] Wrong Gremlin results through REST interface

Hi all, I'm using Gremlin to perform a recommendation query. Locally in the gremlin shell I get amazingly useful results. However when I use the webadmin gremlin console I get different results, both locally and in the Heroku addon environment. I get the same wrong results when I use the rest inte

Re: [Neo4j] Wrong Gremlin results through REST interface

Jeroen, can you narrow it down to a simpler operation, like just a division? Perhaps in the conversion from the division result (be it Float, Double, BigDecimal) to JSON something goes awry. In the GremlinPlugin the code for that is: } else if (result instanceof Double || result instanceof Flo

Hi Michael, I would like to provide a better example, but my Groovy is quite poor so it I'll take me some time. However I think the problem isn't in the JSON conversion. Because that would mean the results I get would be the same, but with a different score right? The thing is that I get different

Jeroen, could you try to use the alternative syntax: ... groupCount(m) { it : it += 0.1 } ... It seems to be a problem with evaluation of the string in the javax.ScriptEngine for Groovy Here is the output from my web-console: • gremlin> m = [:];g.v(33).bothE().label.groupCount(m) { it

i managed to get this working by taking the neo4j- jars from my gremlin installation and use those in the dependency folder of spatial, but I'm still not sure in what way I can fix the dependencies. It seems like the spatial distribution is has a newer kernel, though they both seem to be 1.5 -- V

Hi Mike, Neo4j's default APIs are all Java. Have a look at the Neo4j tutorial here: https://github.com/jimwebber/neo4j-tutorial It will take you from the core API right the way through indexing, traversers, Cypher, and into the REST API should you want to go that far up the stack. And it's alr
