By default the value returned by a callable is required to be a unicode object. If the function returns a model instance, its __unicode__ method is not called. Use coerce_to=unicode.

Loading:
{% load navigation_tags %}
Resolves given named URL and returns the relevant breadcrumb label (if available). Usage:
<a href="{% url project-detail project.slug %}">
{% named_crumb project-detail project.slug %}
</a>
Acts like named_crumb() but also wraps the result into a link tag. Usage:
<ul>
<li>{% crumb_link 'auth_login' %}</li>
<li>{% crumb_link 'project-index' %}</li>
</ul>
The result:
<ul>
<li><a href="/accounts/login/">Log in</a></li>
<li><a href="/projects/">Projects</a></li>
</ul>
Please note that you have to use quotes, otherwise the arguments are considered variable names.
Returns a list of sections. Usage:
{% get_breadcrumb_sections as sections %}
{% for section in sections %}
...
{% endfor %}

True if this breadcrumb’s URL corresponds to the current request path.
True if current request path begins with this breadcrumb’s URL.
