Я пытаюсь создать новостной сайт с помощью django, и в структуре данных шаблона, которую я получил на интерфейсе, есть специальная страница сведений об авторе. В бэкэнде мне нужно преобразовать эту авторскую часть в API и интегрировать ее на сайт, но код, который я написал, работает неправильно (я могу добавить одного автора, но когда я пытаюсь добавить второго, я получаю УНИКАЛЬНОЕ ограничение failed post_author.ошибка href.) Как, по-вашему, я должен следовать и какую структуру я должен создать?

Это мой код модели

и это json-версия структуры таблицы, которую я хочу создать
