Reception clerks should see the calendar tab
============================================

In :mod:`lino_welfare.projects.eupen`, a reception clerk (user type
210) now can see the :guilabel:`Calendar` tab because it contains the
:class:`EntriesByClient <lino_welfare.modlib.cal.EntriesByClient>`
panel.

I changed the required roles for that panel from just `OfficeUser` to
`(OfficeUser, OfficeOperatoir)`:

>>> rt.models.cal.EntriesByClient.get_view_permission(p210)
True

I added a :meth:`__getitem__` method to :class:`BaseLayout` to make
the following doctest snippet more readable:

>>> print(py2rst(pcsw.Clients.detail_layout['calendar']))
**Kalender** (calendar) [visible for 100 110 120 200 210 220 300 400 410 500 510 800 admin 910]:
- **Kalendereinträge** (cal.EntriesByClient)
- **Aufgaben** (cal.TasksByProject) [visible for 100 110 120 200 300 400 410 500 510 admin 910]
<BLANKLINE>

Above snippets are being tested in :ref:`welfare.specs.users`.

The Welfare test suite is currently failing because :ticket:`2223`
asks to make the contracts tab visible as well. And some details are
waiting customer feedback.

While working on this ticket, I stubled into :ticket:`2226` which
needs to get fixed before :ticket:`2223` can be closed.


aids.ConfirmationChecker
========================

I tried the new :class:`lino_welfare.modlib.aids.ConfirmationChecker`
on their production data::

    $ python manage.py checkdata aids.ConfirmationChecker
    Found 536 and fixed 0 data problems in Income confirmations.
    Found 92 and fixed 0 data problems in Refund confirmations.
    Found 55 and fixed 0 data problems in Simple confirmations.
    Done 3 checkers, found 683 and fixed 0 problems.


I fixed a minor bug causing a traceback when a confirmation had no
granting.


RemoteUserMiddleware without SessionMiddleware
==============================================

Another problem was this::

    Traceback:

    File "/site-packages/django/core/handlers/exception.py" in inner
      41.             response = get_response(request)

    File "/site-packages/django/core/handlers/base.py" in _legacy_get_response
      244.             response = middleware_method(request)

    File "/lino/lino/core/auth/middleware.py" in process_request
      89.             if request.user.get_username() == self.clean_username(username, request):

    File "/lino/lino/core/auth/middleware.py" in clean_username
      110.         backend_str = request.session[auth.BACKEND_SESSION_KEY]

    File "/site-packages/django/contrib/sessions/backends/base.py" in __getitem__
      57.         return self._session[key]

    Exception Type: KeyError at /
    Exception Value: '_auth_user_backend'
