Neo4J/py2neo——在事务中创建“关系”？

Question

在交易之外我可以这样做：

from py2neo import Graph, Node, Relationship
graph = Graph()
graph.create(Relationship(node1, "LINKS_TO", node2))

我可以在交易中做类似的事情吗？:

tx = graph.cypher.begin()
tx.append(Relationship(node1, "LINKS_TO", node2))  # This doesn't work

还是我必须手动将其写成密码查询？

Answer 1

好的，知道了。

from py2neo import Graph, Relationship
from py2neo.cypher import CreateStatement

graph = Graph()
tx = graph.cypher.begin()

statement = CreateStatement(graph)
statement.create(Relationship(node1, "LINKS_TO", node2))
tx.append(statement)

tx.commit()
