Python字典可以作为Neo4j文本映射传递吗？

我是从Neo4j和Python开始的新手。我试图使用Python驱动程序将一些数据填充到Neo4j中

我想知道是否有可能将Python字典作为Neo4j文档中描述的文字映射来传递

这将使我能够立即设置应用程序节点属性。属性因节点而异，因此代码会变得难看

下面给出了一个例子

node1 = {
  'def': '"A protein transport process that contributes to protein import into the nucleus, and that results in the vectorial transfer of a cargo-carrier protein complex through the nuclear pore complex from the cytoplasmic side to the nucleoplasmic side of the nuclear envelope." [GOC:curators, ISBN:019 8506732, PMID:14570049, PMID:9126736]',
  'id': 'GO:0000060',
  'is_a': ['GO:0006886'],
  'name': 'protein import into nucleus, translocation',
  'namespace': 'biological_process',
  'relationship': ['part_of GO:0006606'],
  'synonym': [ '"protein import into cell nucleus, translocation" EXACT []' ]
}

node2 = {
    'def': '"A protein complex disassembly process that contributes to protein import into the nucleus, and that results in the dissociation of the cargo protein and the carrier (such as an importin alpha/beta heterodimer) from each other and from the nuclear pore complex." [GOC:mah, PMID:14570049, PMID:9126736, PMID:9687515]',
    'id': 'GO:0000061',
    'is_a': ['GO:0043624'],
    'name': 'protein import into nucleus, substrate release',
    'namespace': 'biological_process',
    'relationship': ['part_of GO:0006606'],
    'is_obselete' : True
}

session.run允许将参数传递到Cypher查询中，但是可以将python字典传递到查询中，并作为Neo4j文本映射进行访问

将dict作为参数传递会将其转换为映射，其行为与在Cypher中声明的映射完全相同。我认为你在画一个不存在的区别

some_python_dict = {'a': 1, 'b': 2}
session.run(
    statement="CREATE (x) SET x = {dict_param}",
    parameters={'dict_param': some_python_dict}
)

这正是您通常从语言驱动程序设置节点的方式。如果您正在制作多个DICT，请传递一个DICT列表参数，然后

展开该参数以开始，您将获得最佳性能
