Views
=====

Inheritance map for the ``coins`` app's HTTP views. Each
block lists one project-internal base class (or local mixin)
and the coin views that extend it. Django base classes
(``DetailView`` / ``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 (``coins/views.py``)

Two mixins defined alongside the coin views.
``CoinChildrenSubmenuViewMixin`` extends
:class:`~richy.core.views.SubmenuViewMixin`; ``FetchDataMixin``
carries no project base.
