上面来自bchhun的例子很好，只是你需要从settings.py显式地构建上下文字典。下面是一个未经测试的示例，说明如何从settings.py的所有大写属性(re: "^[A-Z0-9_]+$")自动构建上下文字典。

在settings.py的末尾:

_context = {} 
local_context = locals()
for (k,v) in local_context.items():
    if re.search('^[A-Z0-9_]+$',k):
        _context[k] = str(v)

def settings_context(context):
    return _context

TEMPLATE_CONTEXT_PROCESSORS = (
...
'myproject.settings.settings_context',
...
)

对于那些想要使用@Berislav的方法(自定义模板标签)和if标签的人:

/ app / templatetags / my_settings.py:

from django import template
from django.conf import settings

register = template.Library()

@register.simple_tag
def settings_value(name):
    return getattr(settings, name, "")

模板文件:

<!-- Load your tags -->
{% load my_settings %}
{% settings_value 'ENABLE_FEATURE_A' as ENABLE_FEATURE_A %}

{% if ENABLE_FEATURE_A %}
<!-- Feature A stuffs -->
{% endif %}

查看django-settings-export(免责声明:我是这个项目的作者)。

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 }}

另一种方法是创建一个自定义模板标签，它可以让您从设置中获取值。

@register.tag
def value_from_settings(parser, token):
    try:
        # split_contents() knows not to split quoted strings.
        tag_name, var = token.split_contents()
    except ValueError:
        raise template.TemplateSyntaxError, "%r tag requires a single argument" % token.contents.split()[0]
    return ValueFromSettings(var)

class ValueFromSettings(template.Node):
    def __init__(self, var):
        self.arg = template.Variable(var)
    def render(self, context):        
        return settings.__getattr__(str(self.arg))

然后你可以使用:

{% value_from_settings "FQDN" %}

将它打印在任何页面上，而无需跳过上下文处理器的约束。

Django提供了对模板中某些常用的设置常量的访问，比如settings。MEDIA_URL和一些语言设置，如果你使用django内置的通用视图或在render_to_response快捷函数中传入context实例关键字参数。以下是每种情况的示例:

from django.shortcuts import render_to_response
from django.template import RequestContext
from django.views.generic.simple import direct_to_template

def my_generic_view(request, template='my_template.html'):
    return direct_to_template(request, template)

def more_custom_view(request, template='my_template.html'):
    return render_to_response(template, {}, context_instance=RequestContext(request))

这些视图都有一些常用的设置，比如settings。模板可用的MEDIA_URL为{{MEDIA_URL}}，等等。

如果你在设置中寻找对其他常量的访问，那么只需将你想要的常量解包，并将它们添加到你在视图函数中使用的上下文字典中，如下所示:

from django.conf import settings
from django.shortcuts import render_to_response

def my_view_function(request, template='my_template.html'):
    context = {'favorite_color': settings.FAVORITE_COLOR}
    return render_to_response(template, context)

现在你可以访问设置了。在模板中使用{{FAVORITE_COLOR}}。
