Forms
=====

The ``shares`` app provides a single user-facing form -- the
share creation / edit form. It is one of the per-app
subclasses of :class:`~richy.core.forms.BaseUserItemForm` (see
:doc:`/modules/core/forms`), narrowed to :class:`Share` and
extended with a Yahoo Finance ticker resolution check.

UserShareForm
-------------

Concrete share variant of
:class:`~richy.core.forms.BaseUserItemForm`. Sets
``item_model = Share`` and layers a Yahoo Finance ticker
resolution check on top of the inherited duplicate /
uppercase symbol validation -- if the entered symbol returns
no prices for the past day, the form raises a validation
error rather than letting an unknown ticker reach the
database.
