如何解决运行 sudo on manage.py 导致无法连接到 PSQL？

Question

所以我遵循了这个 Whosebug 线程 Burhan Khalid 的解决方案：Using Django models in external python script 并在我的 command.py

中包含以下代码

import os
from django.core.management.base import BaseCommand, CommandError

from chat.models import Account, Client, Trader


class Command(BaseCommand):
     help = 'Does some magical work'

     def __str__(self):
        return "Your driver!"

     def handle(self, *args, **options):
         print(Client.objects.all())

当我运行命令 py manage.py command 时，运行非常完美但是，我正在尝试将它连接到 Twisted 反应器，因此需要我使用 sudo 运行项目。现在，当我执行运行 sudo py manage.py command 时，它对我来说非常失败，这是错误的最后一部分：

File "/Library/Frameworks/Python.framework/Versions/3.4/lib/python3.4/site-packages/psycopg2/__init__.py", line 164, in connect
    conn = _connect(dsn, connection_factory=connection_factory, async=async)
django.db.utils.OperationalError: FATAL:  role "root" does not exist

所以我假设运行ning sudo 搞砸了 psycopg2/psql？有没有办法解决？

这是我的 settings.py 文件：

谢谢

您应该在 DATABASES 字典中填写 USER 字段。像这样：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'db',
        'USER': 'django',
        'PASSWORD': '',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

否则将使用当前用户的名称（例如root）。
