例如……

$ pip install django-settings-export

settings.py

TEMPLATES = [
    {
        'OPTIONS': {
            'context_processors': [
                'django_settings_export.settings_export',
            ],
        },
    },
]

MY_CHEESE = 'Camembert';

SETTINGS_EXPORT = [
    'MY_CHEESE',
]

template.html

<script>var MY_CHEESE = '{{ settings.MY_CHEESE }}';</script>

如果使用基于类的视图:

#
# in settings.py
#
YOUR_CUSTOM_SETTING = 'some value'

#
# in views.py
#
from django.conf import settings #for getting settings vars

class YourView(DetailView): #assuming DetailView; whatever though

    # ...

    def get_context_data(self, **kwargs):

        context = super(YourView, self).get_context_data(**kwargs)
        context['YOUR_CUSTOM_SETTING'] = settings.YOUR_CUSTOM_SETTING

        return context

#
# in your_template.html, reference the setting like any other context variable
#
{{ YOUR_CUSTOM_SETTING }}

$ pip install django-settings-export

settings.py

TEMPLATES = [
    {
        'OPTIONS': {
            'context_processors': [

MY_CHEESE = 'Camembert';

SETTINGS_EXPORT = [

template.html

<script>var MY_CHEESE = '{{ settings.MY_CHEESE }}';</script>

将这段代码添加到名为context_processors.py的文件中:

from django.conf import settings as django_settings


def settings(request):
    return {
        'settings': django_settings,
    }

然后，在你的设置文件中，包括一个路径，如'speed .core.base.context_processors。在TEMPLATES中的context_processors设置中的settings'(包含你的应用程序名称和路径)。

(例如，你可以看到settings/base.py和context_processors.py)。

然后可以在任何模板代码中使用特定的设置。例如:

{% if settings.SITE_ID == settings.SPEEDY_MATCH_SITE_ID %}

更新:上面的代码向模板公开了所有设置，包括敏感信息，如SECRET_KEY。黑客可能滥用此特性在模板中显示此类信息。如果你只想将特定的设置暴露给模板，请使用下面的代码:

def settings(request):
    settings_in_templates = {}
    for attr in ["SITE_ID", ...]: # Write here the settings you want to expose to the templates.
        if (hasattr(django_settings, attr)):
            settings_in_templates[attr] = getattr(django_settings, attr)
    return {
        'settings': settings_in_templates,
    }

If we were to compare context vs. template tags on a single variable, then knowing the more efficient option could be benificial. However, you might be better off to dip into the settings only from templates that need that variable. In that case it doesn't make sense to pass the variable into all templates. But if you are sending the variable into a common template such as the base.html template, Then it would not matter as the base.html template is rendered on every request, so you can use either methods.

如果您决定使用template tags选项，那么使用下面的代码，因为它允许您传入一个默认值，以防有问题的变量未定义。

例如:get_from_settings my_variable as my_context_value

例如:get_from_settings my_variable my_default as my_context_value

class SettingsAttrNode(Node):
    def __init__(self, variable, default, as_value):
        self.variable = getattr(settings, variable, default)
        self.cxtname = as_value

    def render(self, context):
        context[self.cxtname] = self.variable
        return ''


def get_from_setting(parser, token):
    as_value = variable = default = ''
    bits = token.contents.split()
    if len(bits) == 4 and bits[2] == 'as':
        variable = bits[1]
        as_value = bits[3]
    elif len(bits) == 5 and bits[3] == 'as':
        variable     = bits[1]
        default  = bits[2]
        as_value = bits[4]
    else:
        raise TemplateSyntaxError, "usage: get_from_settings variable default as value " \
                "OR: get_from_settings variable as value"

    return SettingsAttrNode(variable=variable, default=default, as_value=as_value)

get_from_setting = register.tag(get_from_setting)

IanSR和bchhun都建议在设置中覆盖TEMPLATE_CONTEXT_PROCESSORS。请注意，这个设置有一个默认值，如果在不重新设置默认值的情况下重写它，可能会导致一些问题。在最近的Django版本中，默认值也发生了变化。

https://docs.djangoproject.com/en/1.3/ref/settings/#template-context-processors

默认的TEMPLATE_CONTEXT_PROCESSORS:

TEMPLATE_CONTEXT_PROCESSORS = ("django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.core.context_processors.static",
"django.contrib.messages.context_processors.messages")
