Neo4J / py2neo - 在交易中創建“關系”？

Question

在交易之外，我可以這樣做：

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

我可以在交易中做類似的事嗎？：

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

或者我是否必須手動將其寫為密碼查詢？

Answer 1

好的，我知道了。

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()
