Is $current not working with traverse?

[Vitor Enes Duarte]

Hi,

create class TestV extends V
create class TestE extends E


create vertex TestV set name = 'test1'
create vertex TestV set name = 'test2'
create vertex TestV set name = 'test3'

create edge TestE from (select from TestV where name = 'test1') to (select from TestV where name = 'test2')
create edge TestE from (select from TestV where name = 'test2') to (select from TestV where name = 'test3')



select $all, $current from TestV
let $all = (traverse out('TestE') from $current )


select $all, $current from TestV
let $all = (traverse out('TestE') from (select from TestV where name = 'test1') )

The first query does not return the expected and the second query shows that the first should work.
Is there a problem with $current here, or am I doing something wrong?

Sorry to push this.

Is this an issue or am I missing something?

Hi Vitor,

I'm looking at that (actually thanks to this I found a regression on 2.1-snapshot and I'm fixing it too).

I'll give you a feedback ASAP

Luigi

Ok, I think there is a problem in the first query. I guess in the inner traverse, when you use the $current variable, you are referring to the current record in parent select, right?

In this case you have to use $parent.$current 

so the query should be

select $all, $current from TestV

let $all = (traverse out('TestE') from $parent.$current )

Let me know if it works for you

BTW, I also fixed the regression on 2.1 and pushed it in develop branch, so it also works there.

Thanks

Luigi

Yes. I just read the docs again and its there. Sorry for the trouble.
Waiting for 2.1 :)


Thanks,
Vitor,
