A template tag to create an absolute URI.

absurl.py

from django.template import Library
from django.templatetags.future import URLNode, url

register = Library()

class AbsoluteURLNode(URLNode):
    def __init__(self, view_name, args, kwargs, asvar, legacy_view_name=True):
        super(AbsoluteURLNode, self).__init__(view_name, 
            args, 
            kwargs, 
            None, 
            legacy_view_name)
        self.abs_asvar = asvar
    
    def render(self, context):
        path = super(AbsoluteURLNode, self).render(context)
        url = context['request'].build_absolute_uri(path)
        
        if self.abs_asvar:
            context[self.abs_asvar] = url
            return ''
        else:
            return url
        

def absurl(parser, token):
    node_instance = url(parser, token)
    return AbsoluteURLNode(view_name=node_instance.view_name, 
        args=node_instance.args, 
        kwargs=node_instance.kwargs,
        asvar=node_instance.asvar,
        legacy_view_name=node_instance.legacy_view_name)


absurl = register.tag(absurl)

Updated to accommodate 'asvar':

{% absurl 'path.to.view' as varname %}

This is just what I needed! Thanks!
