python - OrientDB issue creating vertex in transaction -

-

i think there problem when creating records in graph using transactions. vertices created during transaction stored in cluster #3, when check on studio webapp vertex created in tx has class 'unknown'

here code:

client = pyorient.orientdb("localhost", 2424) client.connect("xxx", "xxx") client.db_open("admin", "admin")  people_cluster = client.command("create class people extends v") client.command("create vertex people content {'name': 'dummy', 'age': 21}")  attrs = {'@people': {'name': 'another_me', 'age': 31}} res = client.record_create(people_cluster[0], attrs)  attrs2 = {'@people': {'name': 'me', 'age': 30}} create_rec_cmd = ( client.get_message(pyorient.record_create) ).prepare((people_cluster[0], attrs2))  tx = tx.commit() tx.begin() tx.attach(create_rec_cmd) tx.commit()  # returns 'dummy' , 'another_me', people created in tx not present res = client.command("select people")  print(res[0]) => {'@people':{'age': 21, 'name': 'dummy', 'version':2,'rid':'#13:0'} print(res[1]) => {'@people':{'age': 31, 'name': 'another_me'},'version':1,'rid':'#13:1'}  # ones created in transaction found in cluster #3, no class print(client.command("select #3:0")[0]) => {{'name': 'me', 'age': 30},'version':1,'rid':'#3:0'}

i have activated debug option in xml config, , log doesn't give information:

the pyorient docs have following example (with few lines removed clarity)...

tx = client.tx_commit() tx.begin()  # create new record rec1 = { 'accommodation': 'home', 'work': 'some work', 'holiday': 'surf' } rec_position1 = client.record_create( -1, rec1 )  tx.attach( rec_position1 )

the source code record_create follows...

def record_create(self, *args): return self.get_message("recordcreatemessage") \     .prepare(args).send().fetch_response()

your code running get_message , prepare functions, not send , fetch_response. suspect problem lies.
