我可以从Django的模板中访问settings.py中的常量吗?

我有一些东西在设置。py，我想能够从模板访问，但我不知道如何做到这一点。我已经试过了

{{CONSTANT_NAME}}

但这似乎并不奏效。这可能吗?

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}}';

我发现最简单的方法是一个自定义模板标签:

from django import template
from django.conf import settings

register = template.Library()

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

用法:

{% settings_value "LANGUAGE_CODE" %}

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',
...
)

一个更完整的实现。

/项目/ settings.py

APP_NAME = 'APP'

- app - templatetags settings_value . py

from django import template
from django.conf import settings
 
register = template.Library()
 
@register.simple_tag
def settings_value(name):
    return getattr(settings, name, "")

/app/templates/index.html

<!DOCTYPE html>
{% load static %}
{% load settings_value %}
<head>
    <title>{% settings_value "APP_NAME" %}</title>
...

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> ...
