OrientDB在事务中创建顶点问题

Question

我认为使用事务在图表中创建记录时会出现问题。 在事务期间创建的顶点总是存储在集群3中，当我检查studio webapp时，在tx中创建的顶点的类为“Unknown”

代码如下：

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()

# This returns 'dummy' and 'another_me', but the people created in the tx is not present
res = client.command("select from 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'}

# The ones created in the transaction are found in the cluster #3, but with no class
print(client.command("select from #3:0")[0]) => {{'name': 'me', 'age': 30},'version':1,'rid':'#3:0'}

我在xml配置中激活了debug选项，日志中没有提供太多信息：

Answer 1

pyorient docs有以下示例（为了清楚起见，删除了一些行）。。。在

tx = client.tx_commit()
tx.begin()

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

tx.attach( rec_position1 )

record_create的源代码如下。。。在

^{pr2}$

您的代码只运行get_message和prepare函数，而不是send和{}。我想这就是你的问题所在。在
