decode RID from LinkBag in pyorient

[finn]

Hi,

I realized that the previous question that I have asked is not clear and concise enough, so I did some research and ask it again :D.

I am testing the GRAPH example from GitHub:mogui/pyorient. The example creates a database named ‘animals’, within which exists a record #11:0. I use orient-console and got the record:

orientdb {db=animals}> select from animal
----+-----+------+----+------+--------
# |@RID |@CLASS|name|specie|out_Eat
----+-----+------+----+------+--------
0 |#11:0|Animal|rat |rodent|[size=1]
----+-----+------+----+------+--------

And I can get the type of the ‘out_Eat’ field like this:

orientdb {db=animals}> select out_Eat.type() from animal
----+------+-------
# |@CLASS|out_Eat
----+------+-------
0 |null |LINKBAG
----+------+———

However I can NOT get the RIDs of ‘out_Eat’ using pyorient. The related code and output is like:

>>> record = client.query("select * from Animal")[0]

>>> record.oRecordData
{'out_Eat': <pyorient.types.OrientBinaryObject object at 0x1018750b8>, 'name': 'rat', 'specie': 'rodent’}

>>> record.oRecordData['out_Eat']
<pyorient.types.OrientBinaryObject object at 0x1018750b8>

>>> record.oRecordData['out_Eat'].__dict__
{'b64': 'AQAAAAEADQAAAAAAAAAA’}

>>> record.oRecordData['out_Eat'].getBin()
b'\x01\x00\x00\x00\x01\x00\r\x00\x00\x00\x00\x00\x00\x00\x00’

>>> record.oRecordData['out_Eat'].getRaw()
‘_AQAAAAEADQAAAAAAAAAA_'

How can I get RID info stored in the ‘out_Eat’ field? Please throw in a light, thanks.

Did you ever happen to find a solution to this? I'm having the same problem. Thanks!

Hi,

have you tried with this?

E.g

requiredObj = client.command("select from chat where name='%s' and room='%s'" % ("chat 1","1"));
print(requiredObj[0])




Hope it helps.

Are you sure you're replying to the correct thread? This is asking about getting the RID information from a pyorient OrientBinaryObject that contains the RIDs of attached items.

Hi,

you could use these commands

requiredObj = client.command(' select expand(out("Eat")[0]) from Animal')


print(requiredObj[0]._rid)

For more information you can see this link

Hope it helps.

Hi,

Any way of doing this without referring to the protected member "_rid".

It works, it's what I'm using, but not very pythonic...

Thanks,

Graham
