Remove edges while deleting a vertex

[Munish Chopra]

Hi,

I am using orinetdb 1.7-rc2 and need some information about cleanup of edges. I have a user and group vertex and using an edge to link users with the group.

I am creating user as 

insert into user set name = 'test'

and similarly group as

insert into group set name = 'test_group'

Now if a user wants be a part of group, I am using an edge to link them

create edge userIngroup from user to group;

My edge has following properties as, I dont't want multiple edges between same vertexes

'CREATE PROPERTY UserInGroup.in LINK Group',

'CREATE PROPERTY UserInGroup.out LINK User',

'ALTER property UserInGroup.out MANDATORY=true',

'ALTER property UserInGroup.in MANDATORY=true',

'CREATE INDEX UniqueUserInGroup on UserInGroup(out, in) UNIQUE',

Now if I delete a vertex either by using "delete from" or "delete vertex", it does not remove the edge.

Lets say I executed

delete vertex user where name = 'test'

The edge still remains but if I execute

select expand(in('UserIngroup')) from group

It gives an error.

SEVE Internal server error:

java.lang.NullPointerException [ONetworkProtocolHttpDb]

How can I remove all the edges when a vertex is deleted. Can this be handled through orinentdb

P.S: I am using Orientdb REST API to execute these sql

Regards,

Munish

To add into this, This works fine if I work through Orinetdb Studio but create problem through REST API Only. 

Are these API's not upgraded ?

Thanks in advance

Hi Luca,

Thanks for the reply.

Yes Class Group and User extends V and edge UserInGroup extends E

Hi Munish,

may you try with 1.7-SNAPSHOT to understand if the bug has been already fixed?

Thanks,

So, is this fixed?

Hi Luca,

Nope, I am still trying to make it work. If I have soft edges, this works fine. But create problem with concrete edges.

Munish
