Question

所以我从这个stackoverflow线程Burhan Khalid跟随command.py的解决方案，并在我的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())

中包含以下代码

py manage.py command

运行命令sudo py manage.py command时运行完美但是，我试图将它连接到Twisted反应器，因此需要我使用sudo运行项目。现在，当我运行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时，它在我身上失败了，因为这是错误的最后一部分：

sudo

所以我假设psycopg2/psql混淆了settings.py？有没有办法解决？

您应填写USER字典中的DATABASES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）。
