python - "settings.DATABASES is improperly configured"与 django 1.6

Question

我正在 win7 上使用 pycharm 3 和 python/django 在可移植环境中进行开发。我决定尝试将 postgresql 添加到我的项目(“rob1”)中，该项目位于我的 virtualenv“R1”中，并且我使用了 http://sourceforge.net/projects/pgsqlportable/

我更改了 settings.py 以包括:

DATABASES = {
'default': {
    'ENGINE':'django.db.backends.postgresql_psycopg2',
    'NAME': 'test',
    'USER': 'postgres',
    'PASSWORD': '123',
    'HOST': 'localhost',
    'PORT': '5432',
}
}

从民意调查教程 (https://docs.djangoproject.com/en/dev/intro/tutorial01/) 创建模型作为测试后，我运行 syncdb 并得到:

运行 manage.py diffsettings 我得到

Process finished with exit code 0

编辑:上面有更多错误信息，只有一个settings.py文件(在rob1中)

既然你让我开始寻找设置 .py 中有一个额外的区域:

# Parse database configuration from $DATABASE_URL
import dj_database_url
DATABASES['default'] =  dj_database_url.config()

谁能告诉我如何解决这个问题？

Answer 1

如果你正在使用dj_database_url.config()，你还需要设置DATABASE_URL:

DATABASE_URL = "postgres://postgres:123@localhost:5432/test"
#                          ^user    ^pw ^host     ^port ^dbname
