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?

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}}';

我喜欢Berislav的解决方案，因为在简单的网站上，它干净有效。我不喜欢的是随意地暴露所有的设置常数。所以我最后是这样做的:

from django import template
from django.conf import settings

register = template.Library()

ALLOWABLE_VALUES = ("CONSTANT_NAME_1", "CONSTANT_NAME_2",)

# settings value
@register.simple_tag
def settings_value(name):
    if name in ALLOWABLE_VALUES:
        return getattr(settings, name, '')
    return ''

用法:

{% settings_value "CONSTANT_NAME_1" %}

This protects any constants that you have not named from use in the template, and if you wanted to get really fancy, you could set a tuple in the settings, and create more than one template tag for different pages, apps or areas, and simply combine a local tuple with the settings tuple as needed, then do the list comprehension to see if the value is acceptable. I agree, on a complex site, this is a bit simplistic, but there are values that would be nice to have universally in templates, and this seems to work nicely. Thanks to Berislav for the original idea!

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> ...

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>
...
