使用Neography + Heroku的NEO4j中的数组

Question

I am running a rake process that imports my data into Neo4j. It's all fine until arrays come up. Here's a sample:

{:spelling=>"the", :letters=>["T","H","E"], :length=>2, :rank=>1, :part_of_speech=>"article"}

Here's the ruby code for importing it that fails:

node = @neo.create_unique_node("words", "spelling_phonemes", a[:spelling]+','+a[:phonemes], {"spelling" => a[:spelling], "length" => a[:length], "letters" => a[:letters].split(','), "rank" => a[:rank], "part_of_speech" => a[:part_of_speech]})

Here's the error: Unknown property type on: [T, H, E], class java.util.ArrayList

It's working fine on locally. What gives! From reading around, it seems likes ArrayList might be the issue as only type Array works. If that's the case, how do I ensure that the ruby array is casted/converted properly as a Java Array ?! Thanks!

Also, using neo4j 2.0 locally and Heroku is 1.8.1 I think.

Answer 1

1.8.1是古老的版本，可能与任何最近的Neographic版本都不兼容...如果您希望使用最新的远程托管版本（在2.0上），请尝试http://www.graphenedb.com
