Question

def save_local_setting_JSON(dest, content):
        fwrite  = open(dest, 'wb')
        dict_json = eval(json.dumps(content))
        string_json =json.dumps(dict(dict_json))
        fwrite.write('EMAIL_DEVELOPMENT='+string_json+"\n")
        fwrite.close()

def config_mail_show(request, template='admin/config_mail.html'):
    form = forms.ConfigMailForm()# for for user input their mail config
    context = {
                'site_host' : settings.SITE_HOST,
                'default_from_email' : settings.DEFAULT_FROM_EMAIL,
                'email_host' : settings.EMAIL_HOST,
                'email_port' : settings.EMAIL_PORT,
                'email_host_user' : settings.EMAIL_HOST_USER,
                'email_host_password' : settings.EMAIL_HOST_PASSWORD,
                'email_use_tls' : settings.EMAIL_USE_TLS,
                'form':form
               }
    if request.method == "POST":
        form = forms.ConfigMailForm(request.method)
        save_local_setting_JSON('local_setting.py', request.POST)   
    return render_to_response(template, context)

local_setting.py将采用以下格式：

EMAIL_DEVELOPMENT={"email_host_password": "xxxxxx", "site_host": "127.0.0.1:8000", "default_from_email": "xxx xxx <xxx@xxx.xxx>", "email_use_tls": "False", "email_port": "25","email_host_user": "xxx@xxx.xxx", "email_host": "smtp.xxx.xx"}

在settings.py中我添加了

from local_setting import *
if EMAIL_DEVELOPMENT.has_key('save'):
    SITE_HOST = EMAIL_DEVELOPMENT['site_host']
    DEFAULT_FROM_EMAIL = EMAIL_DEVELOPMENT['default_from_email']
    EMAIL_HOST = EMAIL_DEVELOPMENT['email_host']
    EMAIL_PORT =EMAIL_DEVELOPMENT['email_port']
    EMAIL_HOST_USER = EMAIL_DEVELOPMENT['email_host_user']
    EMAIL_HOST_PASSWORD = EMAIL_DEVELOPMENT['email_host_password']
    EMAIL_USE_TLS = EMAIL_DEVELOPMENT['email_use_tls']
else:# My Development
    SITE_HOST = '127.0.0.1:8000'
    DEFAULT_FROM_EMAIL = 'xxxxx'
    EMAIL_HOST = 'xxxxx'
    EMAIL_PORT = 25
    EMAIL_HOST_USER ='xxxx'
    EMAIL_HOST_PASSWORD = 'xxxxx'
    EMAIL_USE_TLS = False

我不确定这是使用户界面为用户提供自己的配置（例如Mail）的好方法。

这里的每个人都可以做出这样的好选择吗？

Answer 1

我喜欢django-dbsettings来处理可配置的设置是运行时。

Answer 2

settings.py适用于网站范围的设置。如果您希望每个用户都有自己的设置，请创建一个名为user_settings的模型（当然，使用FK到Users模型）并使用它来存储每个用户的设置。

Answer 3

无论你走哪条路，它都会变成黑客 - 我保证。

那就是说，我认为你走在了正确的轨道上。将设置存储在数据库中似乎是一个坏主意，因为数据库连接设置可以在settings.py文件中找到，这可能会导致一些非常糟糕的问题。

您使用JSON并将数据存储为磁盘文件的想法可能是最好的方法，因为如果不在数据库中，它还会如何存储？

我对你试图实现这一目标的方式的唯一反应是，对这些EMAIL_HOST = EMAIL_DEVELOPMENT['email_host']这样的所有行进行手工编码似乎真的很蹩脚。只检查本地设置JSON中是否存在该值并自动返回它会更容易。

这是一些hacky和未经测试的概念代码。将settings.py复制到settings_default.py，这将成为新的settings.py：

settings.py

from local_settings import EMAIL_DEVELOPMENT
import settings_default as defaults
import sys

class DynamicSettings(object):
    def __getattr__(self, key):
        if hasattr(EMAIL_DEVELOPMENT, key):
            return getattr(EMAIL_DEVELOPMENT, key.lower())
        else:
            return getattr(defaults, key)

sys.modules[__name__] = DynamicSettings()

Answer 4

也许以下内容可行：

class _DynamicMailSettings(object):
    @property
    def get_mail_host(self):
        result = 'smtp.mydomain.com' #replace with DB query
        return result
_dynamic_mail_settings = _DynamicMailSettings()

EMAIL_HOST = _dynamic_mail_settings.get_mail_host

我没有在django settings.py中测试它，但它可以在一个独立的python文件中运行。

使用户输入可以自定义settings.py吗？
