            Class clazz = o.getClass();
            while (!clazz.equals(Model.class)) {
                Collections.addAll(fields, clazz.getDeclaredFields());
                clazz = clazz.getSuperclass();
            }

            // relations
            for (Field field : fields) {
                ......
