* **WIP:** This app is still being developed and documented!

* **NOTE:** Presently *only* supports Python 3.5+ and Django 1.9+ (see `issue
#1 <>`_)

Hierarchical view system for Python Django.

Define an arbitrary hierarchical URL structure in your ````, define
how breadcrumbs get generated for each view, and then this package will
automatically generate an ``urlpatterns`` list and breadcrumbs attached to
the request object that can be easily rendered in any page, to easily link
"up" the view hierarchy.


* Supports both Class Based Views and simple functional views

* Auto-generates an ``urlpatterns`` for any nested URL pattern, keeping
your ``urlpatterns`` more DRY instead of repeating common URL pattern

* Automatically generates breadcrumbs with both title and URL available as
``request.breadcrumbs`` for each node in ancestor tree

* Simple Python package: No configuration changes needed

Quick start


1. Install django_view_hierarchy and put in requirements file
2. Using decorators or mixins, enhance some views to be "breadcrumb aware"
3. Create a view hierarchy in an urlpatterns including these views


1. Install

.. code-block:: bash

pip install django_view_hierarchy

2. Use decorator or mixin to add view hierarchy to views

For Class Based Views, do the following:

.. code-block:: python

from django.views import View
from django_view_hierarchy.views import BreadcrumbMixin

class UserList(BreadcrumbMixin, View):
breadcrumb = 'All users' # Static

For more complicated examples, you may need to specify a breadcrumb that
involves fetching data from the DB or giving your view a name:

.. code-block:: python
class UserDetailView(BreadcrumbMixin, View):
view_name = 'user_details' # Optionally give view a name
def get_breadcrumb(self):
pk = self.kwargs['pk']
user = User.objects.get(pk=pk)
return user.username

For function-style views, you can do the same thing as follows:

.. code-block:: python
from django_view_hierarchy.decorators import breadcrumb

def user_list_view(request):
return render_to_response('...')

@breadcrumb(lambda request, pk: User.objects.get(pk).username, 'user_details')
def user_detail_view(request, pk):
return render_to_response('...')

3. Configure hierarchy in

For example, to make a set of views like:

* ``/users/`` for a list of all users
* ``/users/<userid>/`` for a particular user
* ``/users/<userid>/followers/`` for a sub-page of a particular user,
showing off their followers

The hierarchy can be built like:

.. code-block:: python
from django_view_hierarchy.helpers import view_hierarchy
urlpatterns = view_hierarchy({
'users': {
'': UserListView,
'(?P<pk>\d+)': {
'': UserDetailView,
'followers': user_followers_view,

Note that Class Based Views *should not* include `as_view`, this will be
done automatically.

5. Use breadcrumbs in views and/or templates

.. code-block:: html

{% for breadcrumb in request.breadcrumbs %}
<a href="{{ breadcrumb.url }}">{{ breadcrumb.title }}</a>
{% endfor %}
