Using Django settings in templates

Question

I want to be able to put certain configuration information in my settings.py file – things like the site name, site url, etc.

If I do this, how can I then access those settings in templates?

Thanks

Let’s say in your settings.py file you have:

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

If you need that in just one or two views:

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)

If you need to access these across a lot of apps and/or views, you can write a context processor to save code:

James has a tutorial on this
online.

Some useful information on the when and if of context processors is available on this very site
here.

Inside your my_context_processors.py file you would:

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

Back in your settings.py, activate it by doing:

TEMPLATE_CONTEXT_PROCESSORS = (
    ...

    # yours
    'my_context_processors.some_context_processor',
)

In your views.py, make a view use it like so:

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)

If you only need a setting or two for a couple views, Context Processor may be overkill since it will add them to ALL views in your app. But if it’s used in a lot of templates, Contest Processor is the way to go.

For the simple one off case just pass whatever setting you need from the view to the template:

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
    })

And access the setting in your template via:

{{ saved_setting }}

If using a class-based view:

#
# 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 }}
