django: get current url within template

get_current_url.py

## views.py
from django.shortcuts import render_to_response
from django.template.context import RequestContext

def home(request):
    return render_to_response('home.html', {},
              context_instance=RequestContext(request))

## don't forget RequestContext, that makes request var can be used in templates

## in template it can be used like this
# {{ request.path }}

## adding following stuff to settings.py 
# TEMPLATE_CONTEXT_PROCESSORS = (
#     'django.core.context_processors.request',
# )
