settings.DATABASES配置不当

Question

这里完全是新手，抱歉

• MacOSX10.8Python2.7(随自制安装)
  • PostgreSQL 9.4(用自制软件安装)
  • psycopg2 2.5 (安装有宏端口)
  • Django 1.0.4 (通过python setup.py install安装)

​

我正在使用本教程，在启动python manage.py shell之后，我运行

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

得到了以下信息：

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文件中的数据库部分如下所示：

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.

所以我搞不懂它为什么说配置不当？

您需要在数据库中指定settings.py字典

包含与Django一起使用的所有数据库设置的字典。它是一个嵌套字典，其内容将数据库别名映射到包含单个数据库选项的字典。

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