Hierarchy of visibilities

[anehx]

Currently, the hierarchy of the visibilities is completely random. This makes it very hard to be restrictive without being too specific.

In my example I want everything to be hidden for an anonymous user except one certain form (including docs, answers, questions and options). So my idea would naturally be to use the caluma.caluma_user.visibilities.Authenticated as base class and whitelist the allowed models:

from caluma.caluma_user.visibilities import Authenticated
from caluma.caluma_core.visibilities import filter_queryset_for
from caluma.caluma_form.schema import Form

class CustomVisibility(Authenticated):
    @filter_queryset_for(Form)
    def filter_queryset_for_form(self, node, queryset, info):
        if info.context.user.is_authenticated:
            return queryset

        return queryset.filter(slug="my-public-form")

    # ...

In this example the filter_queryset_for_form method is never even being executed. We should clarify the current hierarchy or enable proper extending.
