As a side effect of #2157 I updated the roles.py modules of several plugins to reflect a subtle change in permissions definitions: user roles should inherit from UserRole, not from SiteUser.

Sortable virtual fields

>>> from lino import startup
>>> startup('lino_book.projects.adg.settings.doctests')
>>> from lino.api import rt
>>> de = rt.models.cal.Events.get_data_elem('when_text')

>>> de.__class__
<class 'lino.core.fields.VirtualField'>
>>> de.sortable_by
[u'start_date', u'start_time']

>>> de.return_type.__class__
<class 'lino.core.fields.DisplayField'>
>>> de.return_type.sortable_by
[u'start_date', u'start_time']

>>> th = rt.models.cal.Events.get_handle()
>>> col = th.get_columns()[0]
>>> col.__class__
<class 'lino.modlib.extjs.elems.DisplayElement'>
>>> col.name
'when_text'
>>> col.field.sortable_by
[u'start_date', u'start_time']

>>> col.sortable
True
