与多个开发人员一起管理 Django 本地和站点设置？

Question

环顾四周后，我想出了以下代码，这似乎工作得很好，我想知道其他人想出了什么，并且反馈会很棒。

settings/init.py

import sys
import socket

# try to import settings file based on machine name.
try:
    settings = sys.modules[__name__]
    host_settings_module_name = '%s' % (socket.gethostname().replace('.', '_'))
    host_settings = __import__(host_settings_module_name, globals(), locals(), ['*'], -1)
    # Merge imported settings over django settings
    for key in host_settings.__dict__.keys():
        if key.startswith('_'): continue #skip privates and __internals__
        settings.__dict__[key] = host_settings.__dict__[key]

except Exception, e:
    print e
    from settings.site import *

settings/base.py

BASE = 1
SITE = 1
LOCAL = 1

settings/site.py //项目特定

from settings.base import *
SITE = 2
LOCAL = 2

设置/machine_name_local.py //开发人员或主机服务器的计算机特定设置

from settings.site import *
LOCAL = 3

我认为虽然您的代码可能有效，但它不必要地复杂。复杂的代码很少是一件好事，因为它很难调试，并且您的设置模块是您最不想在 Django 项目中引入错误的地方。

拥有一个 settings.py 文件会更容易，其中包含生产服务器的所有设置以及所有开发计算机通用的设置，并在其底部导入 local_settings.py 。然后，开发人员将在 local_settings.py 中添加特定于其计算机的设置。

settings.py：

# all settings for the production server, 
# and settings common to all development machines eg. 
# INSTALLED_APPS, TEMPLATE_DIRS, MIDDLEWARE_CLASSES etc.

# Import local_settings at the very bottom of the file
# Use try|except block since we won't have this on the production server, 
# only on dev machines
try:
    from local_settings import *
except ImportError:
    pass

local_settings.py

# settings specific to the dev machine
# eg DATABASES, MEDIA_ROOT, etc
# You can completely override settings in settings.py 
# or even modify them eg:

from settings import INSTALLED_APPS, MIDDLEWARE_CLASSES # Due to how python imports work, this won't cause a circular import error

INSTALLED_APPS += ("debug_toolbar",)
MIDDLEWARE_CLASSES += ('debug_toolbar.middleware.DebugToolbarMiddleware',)

只需记住不要在生产服务器上上传local_settings.py，并且如果您使用的是 VCS，请将其配置为忽略 local_settings.py 文件。
