I know I'm late to the party. I didn't like any of the popular solutions though:

The block method seems wrong: I think the navigation should be self contained.

The template_tag method seems wrong: I don't like that I have to get the url from the url-tag first. Also, I think the css-class should be defined in the template, not the tag.

I therefore wrote a filter that doesn't have the drawbacks I described above. It returns True if a url is active and can therefore be used with {% if %}:
```
{% load navigation %}
Home
```

The code:

@register.filter(name="active")
def active(request, url_name):
    return resolve(request.path_info).url_name == url_name

Just make sure to use RequestContext on pages with navigation or to enable the request context_processor in your settings.py

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    'django.core.context_processors.request',
)
