+Note that all Insert/Create/Delete overrides are happening on

+L<update|DBIx::Class::ResultSet/update> or
+L<delete|DBIx::Class::ResultSet/delete>, all logic present in this

+L<delete_all|DBIx::Class::ResultSet/delete_all> methods, which will
+invoke the corresponding L<row|DBIx::Class::Row> method on every
