django - settings.DATABASES 配置不当

Question

这里是新手，抱歉

• Mac OSX 10.8 Python 2.7(安装自制软件)
  • PostgreSQL 9.4(安装自制软件)
  • psycopg2 2.5(与 macports 一起安装)
  • Django 1.0.4(通过 python setup.py install 安装)

我正在使用 this tutorial ，在启动 python manage.py shell 之后，我运行了

>>> from django.db import connection
>>> cursor = connection.cursor()

得到以下内容:

Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/django/db/backends/dummy/base.py", line 15, in complain
    raise ImproperlyConfigured("settings.DATABASES is improperly configured. "
ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

我的 settings.py 文件的 DATABASES 部分如下所示:

DATABASE_ENGINE = 'django.db.backends.postgresql_psycopg2'  #postgresql_psycopg2           
DATABASE_NAME = 'mydatabase'                      #mydatabase
DATABASE_USER = 'sarahr6'             # Not used with sqlite3.
DATABASE_PASSWORD = ''         # Not used with sqlite3.
DATABASE_HOST = ''             # Set to empty string for localhost. Not used with sqlite3.
DATABASE_PORT = ''             # Set to empty string for default. Not used with sqlite3.

所以我不明白为什么它说配置不正确？

您需要指定 DATABASES settings.py 中的字典:

A dictionary containing the settings for all databases to be used with Django. It is a nested dictionary whose contents maps database aliases to a dictionary containing the options for an individual database.

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'mydatabase',
        'USER': 'sarahr6',
        'PASSWORD': '',
        'HOST': '',
        'PORT': ''
    }
}
