转换为 ConfigParser 后在 django 中运行 syncdb

Question

所以我最近根据here找到的指南将我的 django 数据库设置转换为使用 settings.ini 文件

我的问题是，现在 syncdb 已停止为新部署工作：

Traceback (most recent call last):
  File "manage.py", line 10, in <module>
    execute_from_command_line(sys.argv)

    cursor = self.make_debug_cursor(self._cursor())

    raise ImproperlyConfigured("settings.DATABASES is improperly configured. "
django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the ENGINE value. Check settings documentation for more details.

settings.ini：

[database]
DATABASE_ENGINE: django.db.backends.postgresql_psycopg2
DATABASE_NAME: postgres
DATABASE_USER: postgres
DATABASE_PASSWORD:
DATABASE_HOST: db
DATABASE_PORT: 5432

settings.py：

import os
import sys
from ConfigParser import RawConfigParser

config = RawConfigParser()
config.read('settings.ini')

DEBUG = bool(os.environ.get('DEBUG', False))
DEBUG_TOOLBAR = bool(os.environ.get('DEBUG_TOOLBAR', False))
TEMPLATE_DEBUG = bool(os.environ.get('TEMPLATE_DEBUG', False))

#Database Config is pulled from the config file
DATABASE_USER = config.get('database', 'DATABASE_USER')
DATABASE_PASSWORD = config.get('database', 'DATABASE_PASSWORD')
DATABASE_HOST = config.get('database', 'DATABASE_HOST')
DATABASE_PORT = config.get('database', 'DATABASE_PORT')
DATABASE_ENGINE = config.get('database', 'DATABASE_ENGINE')
DATABASE_NAME = config.get('database', 'DATABASE_NAME')

我最初开始沿着这条路走，因此我们的服务可以在不同的站点上运行，并具有易于配置的设置管理文件。它还试图让开发环境变得轻松，因为配置不再需要在代码库中，因为它可以存储在其他地方。

我是否有错误地实现了某些东西，或者我是否遇到了问题 22，其中这种类型的设置更改仅在数据库已经同步时才有效？

这是在 Django 1.6.5 中

编辑

我忘了提到 python manage.py diffsettings 返回预期值，所以我知道 manage.py 可以正确访问和解释 settings.ini 文件。

DATABASE_ENGINE = 'django.db.backends.postgresql_psycopg2'  ###
DATABASE_HOST = 'db'  ###
DATABASE_NAME = 'postgres'  ###
DATABASE_PASSWORD = ''  ###
DATABASE_PORT = '5432'  ###
DATABASE_USER = 'postgres'  ###

Django 的数据库配置格式如：

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'mydatabase',
        'USER': 'mydatabaseuser',
        'PASSWORD': 'mypassword',
        'HOST': '127.0.0.1',
        'PORT': '5432',
    }
}

查看docs了解详情。

所以你需要在你的 settings.py 中这样的东西：

DATABASES = {'default':{}}
#Database Config is pulled from the config file
DATABASES['default']['USER'] = config.get('database', 'DATABASE_USER')
DATABASES['default']['PASSWORD'] = config.get('database', 'DATABASE_PASSWORD')
DATABASES['default']['HOST'] = config.get('database', 'DATABASE_HOST')
DATABASES['default']['PORT'] = config.get('database', 'DATABASE_PORT')
DATABASES['default']['ENGINE'] = config.get('database', 'DATABASE_ENGINE')
DATABASES['default']['NAME'] = config.get('database', 'DATABASE_NAME')
