I tried to use Teleporter but i got ArrayOutOfIndexException when i use

I have an csv
ratings.dat (http://files.grouplens.org/datasets/movielens/ml-100k.zip)
that contains this fields:
userID movieID rating
1 1 5
2 1 4
I imported with ETL the user class and movie class now i want to create
with ratings.csv edges
Hi Luca,
thank you for your repl I have created indexes against Movies.id and
Users.id:
User.json
{
config: {
log: info,
parallel: false
},
source: {
file: {
path: D:\\ETL\\users.dat
}
},
extractor: {
row: {
}
},
transformers: [{
csv: {
separator: ^,
columnsOnFirstLine: false,
columns: [id,
Hi Luca,
when I created Occupation class I have created an index on Occupation.id .
*[58:command] DEBUG executed command=sql.create edge rated from (select
from Users where id = $input.userId) to (select from Movies where id =
$input.movieId) set ratings = $input.ratings , rating_date =
This is the output of debug console:
[58:csv] DEBUG Transformer input: 2^648^4^978299913
[58:csv] DEBUG parsing=2^648^4^978299913
[58:csv] DEBUG document={userId:2,movieId:648,rating:4,timestamp:Mon Jan 12
08:44:59 CET 1970}
[58:csv] DEBUG Transformer output:
Solved! The problem are the variables. I changed $input.attribute in
${input.attribute}

How i can split a field with ETL?

3,Grumpier Old Men (1995),Comedy|Romance
I want genres as Array like as [Animation,Children's,Comedy].
I have tried with let blocks but i
Solved. I added split function(myString,separator) in my database then i
used let block.

Hi Riccardo,
I've just documented the PARALLEL keyword here:
You need to create role_id property as link.
Then you have to create edge with this instruction:
create edge enroll from #12:6 to #11:2 set role_id = (select from #13:2);
Then you can get role name in this way:
select role_id.name from enroll where out('enroll')=user_rid

Hi all,
trying Gephi json exporter (localhost: 2480/gephi / ...) I saw that
directed property of edges is ever set to false.
I think that the problem is at line 149 of OServerCommandGetGephi.java
now it work ;)
Thank you very much.
Gianpaolo.

Hi Luca,
i solved the problem with blueprint java API but I'm still trying a
solution that uses a query with Traverse command.
Unfortunatelly $path doesn't work like an array, but is a string. I need a
variable that point to the previous visited node and I think that I will
use $stack variable.
Hi Luca,
$history does not seem to be ordered and $stack is null. I have read that
i need to use $stack in java but i don't find examples or documentation.
Can you help me with some examples?
Thank you,
Gianpaolo.

Solved:
The correct query is
select name, out_.name , $b from A let $b=(select from out_ where
name=$parent.$current.name)
It's only a context problem...
