Question

我使用的是djanog 1.11和postgresql 9.5 ###，

我面临以下错误。但我的django数据库设置不同。

  DATABASES = {
        'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME':'test_db',
        'USERNAME':'rails',
        'PASSWORD':'rails',
        'HOST':'localhost',
        'PORT':'5432',
        }
    }

我认为django将用户作为ubuntu用户传递，它的系统已登录用户。

您的设置有误。

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': '<db_name>',
        'HOST': '<db_host>',
        'USER': '<postgres_user>',
        'PORT': '5432',
        'PASSWORD': '<postgres_user_password>',
    },
}

它是“用户”而非“用户名”

致命：用户＆＃34; ubuntu＆＃34;密码验证失败

我使用的是djanog 1.11和postgresql 9.5 ###，
