Django 5.0.6 compatibility

[LokkiDog]

An error occurs when checking form fields for changes (as far as I understand it).

Django==5.0.6
django-access==0.1.2b2

The error is in the file access/admin.py 498

perm = bool(manager.apply_able(ability, obj.__class__.objects.filter(id=obj.id), request).exists()))

manager.apply_able(ability, obj.__class__.objects.filter(id=obj.id), request) - already gives bool value, exists() - unnecessary

Here is the error trace:

Actually, the apply_able returns a value from the user-defined functional authorization checks, defined by the ApplyAblePlugin . The user-defined functional check should obviously return queryset in any case.

Contrary, the CheckAblePlugin user-defined functional authorization check should return either False, or dictionary.

Therefore, the most probable problem is your own access profile, where you probably use ApplyAblePlugin with your custom functional check returning boolean, like:

        ApplyAblePlugin(
            changeable=lambda queryset, request: return False
        )

instead of properly defined:

        ApplyAblePlugin(
            changeable=lambda queryset, request: return queryset.none()
        )
