Views
=====

Inheritance map for the ``shares`` app's HTTP views. Each block lists
one project-internal base class (or local mixin) and the share views
that extend it. Django base classes (``DetailView`` / ``ListView`` /
``UpdateView`` / ``RedirectView``) and django-braces mixins
(``LoginRequiredMixin``, ``FormMessagesMixin``) are omitted to keep
the picture readable. ``(+ ...)`` after a leaf class lists any *other*
project-internal parents the view also inherits from.

Local mixins (``shares/views.py``)
----------------------------------

Three mixins defined alongside the share views. The two submenu
mixins themselves extend
:class:`~richy.core.views.SubmenuViewMixin`; ``FetchDataMixin``
carries no project base.
