'Session' 对象没有属性 'session'

Question

我收到一条错误消息

这是我的代码块（经过简化，但仍然显示错误）

import neo4j
import sys
import uuid

from neo4j import GraphDatabase


def create_population_point(tx, _point, _uuid, _tl, _tr, _ll, _lr, _band):
    print("Add a record block  A")
    tx.run("CREATE (n:Population_Point 
    {point:$point,uuid:$uuid,TL:$tl,TR:$tr,BL:$bl,BR:$br,Band_1:$band}),"
          "point=_point,uuid=_uuid,tl=_tl,tr=_tr,ll=_ll,lr=_lr,band=_band")


def main():
uri = "neo4j://localhost:7687"
username = "neo4j"
password = "P@ssword2"

databaseConnection = GraphDatabase.driver(uri, auth=(username, password))
databaseSession = databaseConnection.session()
print("Connection established")
print("Variables assigned values")
_point = "D007_S001_T001"
_uuid = uuid.uuid4()
_tl = "28.27291"
_tr = "-81.65765"
_ll = "28.27291"
_lr = "-81.65765"
_band = "455"
print("Ready to execute")
with databaseSession.session() as session:
    result = session.write_transaction(create_population_point, _point, _uuid, _tl, _tr, _ll, 
   _lr, _band)
databaseConnection.close()
print("Connection closed")


if __name__ == "__main__":
    main()

这是抛出错误的行

以 databaseSession.session() 作为会话：

运行 python 3.10.4

首先你创建

databaseSession = databaseConnection.session()

下次使用

with databaseSession.session() as session:

所以最后你尝试使用

databaseConnection.session().session()

这是错误的。

可以直接使用

result = databaseSession.write_transaction(..)

或在

中使用databaseConnection代替databaseSession

with databaseConnection.session() as session:
     result = session.write_transaction(..)

（并删除 databaseSession = databaseConnection.session() 因为你不使用它）

'Session' 对象没有属性 'session'

'Session' object has no attribute 'session'

python
