Lino-Welfare: Not every Person is a Client. An important but almost invisible change, which is a challenge to the framework and mainly to data migration: new model ‘Client’ is now an MTI child of Person.

Optimized error reporting:

• Error message “Part coach1 of <class ‘lino_welfare.modlib.pcsw.models.Person’> got None” replaced by “Invalid RemoteField courses.CourseRequest.person__coach1 (no coach1 in contacts.Person)”. (lino.core.table.Table.get_data_elem()).

• Added “in %s” to rrror message “No LayoutElement for VirtualField user on <class ‘lino.core.modeltools.UnresolvedField’> in ListLayout on pcsw.UsersWithClients” (lino.ui.extjs3.ext_elems.field2elem())

• lino.core.modeltools.resolve_field no longer returns an UnresolvedField but raises an exception

• New method VirtualField.resolve_type is called during kernel.analyze_models.

  virtualfield UsersWithClients.user. Da funktionierte das resolve_field(‘pcsw.Client.coach1’) nicht mehr. Ich habe nicht genau verstanden warum, aber offenbar findet models.get_model zu dem Zeitpunkt die pcsw.Client noch nicht. Workaround: resolve_field erst in kernel.analyze_models aufrufen. Das war nicht einfach: habe eine neue Methode resolve_type gemacht. Das alles war aber unnütz, letzten Endes half nur, dass ich das “populate_cache=False” von models.get_model() entfernt habe. Ich weiß nicht mehr, wieso das da war.
