在模板中使用Django设置[重复]

比如说在你的 settings.py 您拥有的文件:

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

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)

如果需要跨许多应用程序和/或视图访问这些内容,可以编写上下文处理器来保存代码:

詹姆斯有这方面的教程 online .

在这个网站上有一些关于上下文处理器何时和是否可用的有用信息 here .

在你的 my_context_processors.py

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

回到你的生活中 设置.py

TEMPLATE_CONTEXT_PROCESSORS = (
    ...

    # yours
    'my_context_processors.some_context_processor',
)

在你的 views.py ,使视图像这样使用:

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)

#
# 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 }}

如果您只需要一个或两个设置来显示几个视图,上下文处理器可能会有点过头,因为它会将它们添加到应用程序中的所有视图中。但如果在很多模板中使用它,那么竞争处理器就是一个不错的选择。

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

def some_view(request):
    val = settings.SAVED_SETTING
    return render_to_response("index.html", {
        'saved_setting':val
    })

并通过以下方式访问模板中的设置:

{{ saved_setting }}
