Object API: generated schema with in/out relations

[Wouter de Vaal]

Hi,

I'm using Object API and let orient generate a schema for me with the objectDatabaseTx.getMetadata().getSchema().generateSchema() method.

If there is a link to another class, it adds it as a property link, but not as an in/out graph relation:

public class Login extends BasePersistentObject {

    private User belongsTo;

    private String username;

    private String passwordHash;

... more stuff

orientdb {db=orientdbtest}> info class Login

Class................: Login

Super class..........: BasePersistentObject

Default cluster......: login (id=117)

Supported cluster ids: [117]

Cluster selection....: round-robin

PROPERTIES

-------------------------------+-------------+-------------------------------+-----------+----------+----------+-----------+-----------+----------+

 NAME                          | TYPE        | LINKED TYPE/CLASS             | MANDATORY | READONLY | NOT NULL |    MIN    |    MAX    | COLLATE  |

-------------------------------+-------------+-------------------------------+-----------+----------+----------+-----------+-----------+----------+

 username                      | STRING      | null                          | false     | false    | false    |           |           | default  |

 belongsTo                     | LINK        | User                          | false     | false    | false    |           |           | default  |

 passwordHash                  | STRING      | null                          | false     | false    | false    |           |           | default  |

-------------------------------+-------------+-------------------------------+-----------+----------+----------+-----------+-----------+----------+

It has some data:

orientdb {db=orientdbtest}> select from Login

----+------+------+--------+------------+---------+------------------------------------

#   |@RID  |@CLASS|username|passwordHash|belongsTo|persistentObjectUuid                

----+------+------+--------+------------+---------+------------------------------------

0   |#117:0|Login |admin   |somepass    |#120:0   |0820df47-e52b-4050-a876-7c2f8375bc07

...

And we see the belongsTo link is ok, but when I query for out relations it gives nothing:

orientdb {db=orientdbtest}> select out() from Login

----+------+----

#   |@CLASS|out 

----+------+----

0   |null  |[0] 

Is there a way to have the schema be generated with relations? Or am I misunderstanding something here?

Thanks,

Wouter
