Поля администратора модели Django/Wagtail не отображаются в API

Я использую wagtail и у меня есть ModelAdmin под названием sorting. У меня есть PageChooserPanel внутри ModelAdmin. Я отобразил их в API, но он показывает только id таблицы, но не показывает полную информацию. Но в моей базе данных я могу просмотреть их.
