I worked on #1442. A first problem was that the actions didn’t even become visible. It took me one hour to understand that my new idea of having multiple roles per UserType does not work as I expected.

Bruno tested on the production site, and thanks to this I fixed quite some problems which occured after reading an eid card. I cannot currently test these things from my machine because it seems that my card reader doesn’t work with Belgian cards.

One of the problems was a TypeError: 'birth_place' is an invalid keyword argument for this function.

This was because contacts.Person also inherited from BeIdCardHolder (just because when I wrote this I believed that they will manage only clients and no normal persons). And lino.core.utils.models_by_base() seems to not work as expected when the toplevel_only option is True. I’d have expected it to raise a warning when it finds more than one models implementing BeIdCardHolder… Not urgent. But now lino_xl.xl.lib.beid.Plugin.holder_model contains lino_avanti.lib.avanti.models.Client. That’s what I expect it to be.

The birth_place field must indeed be in BeIdCardHolder, not in every implementing class.

Several similar trivial problems.

I renamed UserType.roles to UserTypes.role. En passant I also now differentiate roles modules from user_types modules.
