django-breadcrumbs is a breadcrumb system to Django framework that allow you to add custom breadcrumbs for simple views, generic views and support Django FlatPages app.
In format of a pluggable middleware that add a breadcrumbs callable/iterable in your request object, allowing you to set breadcrumbs (one or more) in each view accepting objects, lists or tuples added from request.breadcrumbs and is iterable, easy to use in templates providing a object with name and url attributes.
Note: For Django 1.x, check for tag 1.0 and patches :)
#1 - Install django-breadcrumbs
Just put in your python path and add breadcrumbs.middleware.BreadcrumbsMiddleware to your MIDDLEWARE_CLASSES. Also, if you did't put request context processor on yours TEMPLATE_CONTEXT_PROCESSORS, add it, ex:
TEMPLATE_CONTEXT_PROCESSORS = (
"django.contrib.auth.context_processors.auth",
"django.core.context_processors.debug",
"django.core.context_processors.i18n",
"django.core.context_processors.media",
"django.contrib.messages.context_processors.messages",
'django.core.context_processors.request',
)
#2 - Adding breadcrumbs
To add breadcrumbs you just need to call request.breadcrumbs('Title',url), ex:
def about(request):
request.breadcrumbs(_("About"),request.path_info)
...
def generic_crud_view(request,model,action):
"""
model = model name
action = action name
"""
request.breadcrumbs([
(_(model.title()),'/crud/%s' % model),
(_('%s %s') % (action.title(),model.title()),'/crud/%s/%s' % (model,action)),
])
...
All modes of add a breadcrumb:
# one by one
request.breadcrumbs( name, url )
# various tuples/lists
request.breadcrumbs( ( (name1, url1), (name2, url2), (name3, url3), ...,) )
request.breadcrumbs( [ [name1, url1], [name2, url2], [name3, url3], ...] )
# objects with attributes name and url in list / tuple format:
request.breadcrumbs( ( obj1, obj2, obj3, obj4, ......) )
request.breadcrumbs( [ obj1, obj2, obj3, obj4, ......] )
Note: You can use request.breadcrumbs safely in any middleware after BreadcrumbsMiddleware or any place where you have request object after BreadcrumbsMiddleware are processed
#3 - Enable FlatPages + Breadcrumbs
FlatPages is a app that allow user create urls with static content and a title. But create breadcrumbs for this kind of 'unknow' url path isn't fun at all, so I modified FlatpageFallbackMiddleware to fill breadcrumbs for each flat page in path.
Is really easy to use, just add breadcrumbs.middleware.FlatpageFallbackMiddleware in your MIDDLEWARE_CLASSES after BreadcrumbsMiddleware and all done!
#4 - Using in templates
To use breadcrumbs in template, only that you need is iterate over breadcrumbs, example:
{% for breadcrumb in request.breadcrumbs %}
<a href="{{ breadcrumb.url }}">{{ breadcrumb.name }}</a>{% if not forloop.last %} >> {% endif %}
{% endfor %}
#5 - Options
django-breadcrumbs have a single option to set in your settings.py:
BREADCRUMBS_AUTO_HOME: defaults to False, If True, breadcrumbs add as first Breadcrumb in list (_("Home"),u"/")
BREADCRUMBS_HOME_TITLE: defaults to _(u'Home')
