假如，你的settings.py有如下配置:

SITE_URL='www.mydomain.tld/somewhere/'
SITE_NAME='My site'

如果你只在少量的views中需要使用她们:

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

def my_view(request, ...):
    response_dict = {
        'site_name': settings.SITE_NAME,
        'site_url': settings.SITE_URL,
    }
    ...
    return render_to_response('my_template_dir/my_template.html', response_dict)

如果你需要在很多apps / views使用这些配置，那么你需要写一个context processor，这样的好处是，可以复用代码:

具体可以参考 这个英文文档

你可以这样编写自己的mycontextprocessors.py文件:

from django.conf import settings

def some_context_processor(request):
    my_dict = {
        'site_url': settings.SITE_URL,
        'site_name': settings.SITE_NAME,
    }

    return my_dict

打开settings.py文件, 通过如下方式激活你的context_processor:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...

    # yours
    'my_context_processors.some_context_processor',
)

打开views.py文件, 通过如下方法使用:

from django.shortcuts import render_to_response
from django.template import RequestContext

def my_view(request, ...):  
    response_dict = RequestContext(request)
    ...
    # you can still still add variables that specific only to this view
    response_dict['some_var_only_in_this_view'] = 42
    ...
    return render_to_response('my_template_dir/my_template.html', response_dict)
