        # We need to transform RailsConnector::Linklist to a string to prevent circular references.
        # Rails 6.0 does not make use of `attribute_for_inspect`, therefore we need to patch `format_for_inspect` directly.
        # `format_for_inspect` in > 6.1 uses two parameters
        #
        # Reason for change: activerecord/lib/active_record/core#inspect might change in future Rails versions.
