These are readable, but not writable. What I want is for widget to
get
"grayed-out" and not be usable when user doesn't have permission to
fill in the field.
Ideally, I think it would make sense to be able to do this as a
requirement to a field, something like:
requires=HAS_MEMBERSHIP(auth.id_group('admin'),auth.user.id),
or
requires=HAS_PERMISSION(...)
or maybe clearer yet, have a permission authenticator:
permission=HAS_MEMBERSHIP(...)
or permission=HAS_PERMISSION(...)
