            if request.user.groups.exists():
                group = request.user.groups.all()[0].name

            if group in allowed_roles:
                return view_func(request, *args, **kwargs)
            else:
                return HttpResponse('You are not authorized to view this page')
        return wrapper_func
    return decorator
