Django snippets: URL based breadcrumbs

def breadcrumbs(url):
    home = ['<li>you are here : <a href="/" title="Breadcrumb link to the homepage.">home</a> &raquo;</li>',]
    links = url.strip('/').split('/')
    bread = []
    for link in links:
        if not link == '':
            bread.append(link)
            this_url = "/".join(bread)
            if not link == links[len(links)-1]:
                this_link = '<li><a href="/%s/" title="Breadcrumb link to %s.">%s</a> &raquo;</li>' % (this_url, link, link)
            else:
                this_link = '<li>%s</li>' % link
            home.append(this_link)
    bcrumb = "".join(home)
    return mark_safe(bcrumb)

This is a simple URL based breadcrumb filter I'm using on a site I'm currently building. To use it, just throw the code into template-tag file, and simply pass the current url in a page template like so

As an example of how to style it, wrap it in a unordered list with an id of breadcrumb, and then in your styles use #breadcrumb li { display: inline; }.

On a contact form for a site user, this will produce something along the lines of

you are here : home » users » username » contact form

Hopefully someone may find it useful.
