我正在开发使用 neo4j 数据库的 django 项目。这是我的 models.py 文件的一部分：

模型.py：

from neo4django.db import models

class User(models.NodeModel):

    firstName = models.StringProperty(max_length=20)
    lastName = models.StringProperty(max_length=20)
    password = models.StringProperty(max_length=50)
    email = models.EmailProperty()
    status = models.BooleanProperty()
    BirthDate = models.DateProperty()
    gender = models.BooleanProperty()

我遵循neo4django 文档并更改 settings.py 文件：setting.py：

DATABASES = {
    'default': {
         'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'.
         'NAME': 'mylifetime',                      # Or path to database file if using sqlite3.
         # The following settings are not used with sqlite3:
         'USER': 'root',
         'PASSWORD': 'password',
         'HOST': '',                      # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP.
        'PORT': '',                      # Set to empty string for default.
    }
}

NEO4J_DATABASES = {
    'default' : {
        'HOST':'localhost',
        'PORT':7474,
        'ENDPOINT':'/db/data'
    }
}

但是当我运行 shell 以在 db 中创建一些节点时，我收到连接被拒绝错误：

似乎是连接错误。你确定 Neo 服务器正在监听 localhost 的 7474 端口吗？

既然是休息，请尝试在 localhost:7474 上使用您的浏览器
