I find the simplest steps to passing variables to your base templates in django is to add a context_processor.py file like so:

In your app create context_processors.py and declare your variables e.g.:

# context_processors.py
def message_processor(request):
    if request.user.is_authenticated:
        no_msgs = request.user.profile.msgs
    else:
        no_msgs = 0
    return {
        'messages' : no_msgs
    }

Then register your process or under TEMPLATES in your settings.py file:

TEMPLATES = [
    {
        ...
            'context_processors': [
                ...
                # custom
                'appname.context_processors.message_processor',
            ],
        },
    },
]

And then you will be able to get that variable anywhere in your app as:

{{ messages }}
