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> ...

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。

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")

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 }}

我发现这是Django 1.3最简单的方法:

views.py 从local_settings导入BASE_URL def根(请求): 返回render_to_response('hero.html'， {'BASE_URL': BASE_URL}) hero.html var BASE_URL = '{{JS_BASE_URL}}';
