Prototypes
==========

Let's add ``message:choose`` to Russian locale.

..  literalinclude:: ../_static/examples/4_prototypes/app_1.py
    :language: python


Take a notice, nouns in Russian version of the :term:`message`
``message:choose`` is used in accusative case instead of nominative one.
So, we added appropriate forms to ``object:article`` and ``object:comment``.
Also, we added default value ``n`` (nominative) for ``case`` parameter.
Obviously, there is a copy-paste work to add ``defaults`` and ``key`` parameters
to each noun in Russian locale.  Let's use :term:`prototype` instead.
