Question

i have a function in views.py , for example something like this :

def get_base_content():
    footer = SiteContent.objects.get(pk=1)
    return {
        "footer" : footer,
}

how can i call this function in my template and use footer variable in it ?

If you want to have this variable shown on all templates, then you need to implement a template context processor.

You just need minimal changes to your code:

def get_base_content(request):
    footer = SiteContent.objects.get(pk=1)
    return {"footer" : footer}

Now, add that to a separate file, call it custom_context.py. In your settings.py add it to your TEMPLATE_CONTEXT_PROCESSORS setting:

TEMPLATE_CONTEXT_PROCESSORS = (
    "django.contrib.auth.context_processors.auth",
    "django.core.context_processors.debug",
    "django.core.context_processors.i18n",
    "django.core.context_processors.media",
    "django.core.context_processors.static",
    "django.core.context_processors.tz",
    "django.contrib.messages.context_processors.messages",
    "myapp.custom_context.get_base_content", # don't forget the comma!
)

Now, in your view code you just need to make sure you are using RequestContext. The easiest way to do that is to use the render shortcut:

from django.shortcuts import render

def myview(request):
   return render(request,'hello.html',{'foo': 'bar'})

In hello.html you’ll have {{ foo }} and {{ footer }}
