Inheritable hook for defining parameter fields
==============================================

I wanted to write documentation about how to configure printable
templates... but I discovered and fixed a subtle problem:

- The :menuselection:`Office --> My excerpts` table never displays
  excerpts of other users even when the user manually sets the `User`
  filter parameter to empty.

This lead to a series of cool new concepts:

- :meth:`lino.core.actors.Actor.get_parameter_fields`
- :meth:`lino.core.model.Model.get_parameter_fields`
- :class:`lino.modlib.users.mixins.My`


TODO: Adapt `lino.modlib.system.mixins.PeriodEvents` to make
use of this new feature.

Configuring printable templates
===============================

Before writing about how to configure printable templates, I had to
tidy up the Lino Welfare documentation tree in order to find the
"entry point" for this howto. It guess that the logical place is in
the `welfare.admin` (since :blogref:`20181031` in
:ref:`welfare.admin.printing`).
