我在manage.py中区分它，并创建了两个单独的设置文件:local_settings.py和prod_settings.py。

在manage.py中检查服务器是本地服务器还是生产服务器。如果它是本地服务器，它将加载local_settings.py，如果它是生产服务器，它将加载prod_settings.py。基本上是这样的:

#!/usr/bin/env python
import sys
import socket
from django.core.management import execute_manager 

ipaddress = socket.gethostbyname( socket.gethostname() )
if ipaddress == '127.0.0.1':
    try:
        import local_settings # Assumed to be in the same directory.
        settings = local_settings
    except ImportError:
        import sys
        sys.stderr.write("Error: Can't find the file 'local_settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file local_settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__)
        sys.exit(1)
else:
    try:
        import prod_settings # Assumed to be in the same directory.
        settings = prod_settings    
    except ImportError:
        import sys
        sys.stderr.write("Error: Can't find the file 'prod_settings.py' in the directory containing %r. It appears you've customized things.\nYou'll have to run django-admin.py, passing it your settings module.\n(If the file prod_settings.py does indeed exist, it's causing an ImportError somehow.)\n" % __file__)
        sys.exit(1)

if __name__ == "__main__":
    execute_manager(settings)

我发现将设置文件分开到两个单独的文件中更容易，而不是在设置文件中做大量的if。

我也在与Laravel合作，我喜欢那里的实现。我试着模仿它，并将其与T. Stone提出的解决方案结合起来(见上文):

PRODUCTION_SERVERS = ['*.webfaction.com','*.whatever.com',]

def check_env():
    for item in PRODUCTION_SERVERS:
        match = re.match(r"(^." + item + "$)", socket.gethostname())
        if match:
            return True

if check_env():
    PRODUCTION = True
else:
    PRODUCTION = False

DEBUG = not PRODUCTION

也许这样能帮到你。

Django 1.5的最佳实践建议对你的设置文件使用版本控制，并将文件存储在一个单独的目录中:

project/
    app1/
    app2/
    project/
        __init__.py
        settings/
            __init__.py
            base.py
            local.py
            production.py
    manage.py

base.py文件包含常见设置(如MEDIA_ROOT或ADMIN)，而local.py和production.py有特定于站点的设置:

在基本文件设置/base.py:

INSTALLED_APPS = (
    # common apps...
)

在本地开发设置文件settings/local.py中:

from project.settings.base import *

DEBUG = True
INSTALLED_APPS += (
    'debug_toolbar', # and other apps for local development
)

在文件生产设置文件设置/production.py:

from project.settings.base import *

DEBUG = False
INSTALLED_APPS += (
    # other apps for production site
)

然后当你运行django时，你添加——settings选项:

# Running django for local development
$ ./manage.py runserver 0:8000 --settings=project.settings.local

# Running django shell on the production site
$ ./manage.py shell --settings=project.settings.production

这本书的作者还在Github上发布了一个示例项目布局模板。

对于我的大多数项目，我使用以下模式:

创建settings_base.py，其中存储所有环境的通用设置 每当我需要使用具有特定要求的新环境时，我都会创建新的设置文件(例如。Settings_local.py)，它继承settings_base.py的内容，并覆盖/添加适当的设置变量(从settings_base import *)

(要使用自定义设置文件运行manage.py，只需使用——settings命令option: manage.py <命令>——settings=settings_you_wish_to_use.py)

为了在不同的环境中使用不同的设置配置，创建不同的设置文件。在部署脚本中，使用——settings=<my-settings.py>参数启动服务器，通过该参数可以在不同的环境中使用不同的设置。

使用这种方法的好处:

Your settings will be modular based on each environment You may import the master_settings.py containing the base configuration in the environmnet_configuration.py and override the values that you want to change in that environment. If you have huge team, each developer may have their own local_settings.py which they can add to the code repository without any risk of modifying the server configuration. You can add these local settings to .gitnore if you use git or .hginore if you Mercurial for Version Control (or any other). That way local settings won't even be the part of actual code base keeping it clean.

我在django split-settings的帮助下管理我的配置。

它是默认设置的临时替换。它很简单，但可配置。并且不需要重构现有设置。

下面是一个小例子(文件示例/settings/__init__.py):

from split_settings.tools import optional, include
import os

if os.environ['DJANGO_SETTINGS_MODULE'] == 'example.settings':
    include(
        'components/default.py',
        'components/database.py',
        # This file may be missing:
        optional('local_settings.py'),

        scope=globals()
    )

就是这样。
