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}}。

如果你希望每个请求和模板都有一个值，那么使用上下文处理器更合适。

方法如下:

Make a context_processors.py file in your app directory. Let's say I want to have the ADMIN_PREFIX_VALUE value in every context: from django.conf import settings # import the settings file def admin_media(request): # return the value you want as a dictionnary. you may add multiple values in there. return {'ADMIN_MEDIA_URL': settings.ADMIN_MEDIA_PREFIX} add your context processor to your settings.py file: TEMPLATES = [{ # whatever comes before 'OPTIONS': { 'context_processors': [ # whatever comes before "your_app.context_processors.admin_media", ], } }] Use RequestContext in your view to add your context processors in your template. The render shortcut does this automatically: from django.shortcuts import render def my_view(request): return render(request, "index.html") and finally, in your template: ... <a href="{{ ADMIN_MEDIA_URL }}">path to admin media</a> ...

    return render_to_response(template, context)

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,
    }

我稍微改进了chrisdew的答案(创建自己的标签)。

首先，创建文件yourapp/templatetags/value_from_settings.py，在其中定义你自己的新标签value_from_settings:

from django.template import TemplateSyntaxError, Variable, Node, Variable, Library
from yourapp import settings

register = Library()
# I found some tricks in URLNode and url from defaulttags.py:
# https://code.djangoproject.com/browser/django/trunk/django/template/defaulttags.py
@register.tag
def value_from_settings(parser, token):
  bits = token.split_contents()
  if len(bits) < 2:
    raise TemplateSyntaxError("'%s' takes at least one " \
      "argument (settings constant to retrieve)" % bits[0])
  settingsvar = bits[1]
  settingsvar = settingsvar[1:-1] if settingsvar[0] == '"' else settingsvar
  asvar = None
  bits = bits[2:]
  if len(bits) >= 2 and bits[-2] == 'as':
    asvar = bits[-1]
    bits = bits[:-2]
  if len(bits):
    raise TemplateSyntaxError("'value_from_settings' didn't recognise " \
      "the arguments '%s'" % ", ".join(bits))
  return ValueFromSettings(settingsvar, asvar)

class ValueFromSettings(Node):
  def __init__(self, settingsvar, asvar):
    self.arg = Variable(settingsvar)
    self.asvar = asvar
  def render(self, context):
    ret_val = getattr(settings,str(self.arg))
    if self.asvar:
      context[self.asvar] = ret_val
      return ''
    else:
      return ret_val

你可以通过以下方式在模板中使用这个标签:

{% load value_from_settings %}
[...]
{% value_from_settings "FQDN" %}

或通过

{% load value_from_settings %}
[...]
{% value_from_settings "FQDN" as my_fqdn %}

as的优点是…这使得它很容易通过一个简单的{{my_fqdn}}在blocktrans块中使用。

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>
