Lino Faggio¶
Continued on yesterday’s “To-Do-Liste Sven” (2013-10-17).
The cal.Calendar model is back. I had replaced it by a system of subscriptions where each user could define application-specific filter criteria per Subscription. This resulted in a system where it was possible for an Event to appear in different Calendars. Which would have been nice, but the problem with that idea is that Ext.ensible.CalendarPanel isn’t designed for it, it wants a list of calendars and each Event pointing to exactly one of them.
So I return back to almost the old system (and that “almost” is what Lino has learned): cal.Event has no direct FK to Calendar, but a get_calendar method. And Lino Welfare users see one Calendar per User while Renamed “Lino Faggio” to “Lino Voga” users see one Calendar per Room.
Updated the Lino Welfare test suite to several recent changes.
New item “Once” in Recurrences.
insert_layout for courses.Line
New field courses.Line every_unit (Recurrences)
Split up lino_xl.lib.cal into more digestable chunks:
models_task
models_guest
models_event
models_calendars
In a first checkin I had tried to turn
lino_xl.lib.cal
into a package containing the above files.
But that would require me to add an explicit app_label
(the feature that app_label “is no longer required for models that are
defined in a models package within an app” is only available in the
development version).
I also did the mistake of naming them
task,
guest,
event and
calendar in a first go.
And didn’t notice that a module called
calendar
is part of the Python standard library.
The funny thing was that this bomb didn’t explode in the Lino test suite,
only in Lino Welfare:

An interesting example of a subtle pitfall!
