Администратор не может одобрить сообщение для требуемого поля like django

В моем проекте django пользователи могут создавать посты. но администратор должен сначала одобрить пост. Затем пользователи могут видеть созданные ими посты в своей временной шкале. Пользователи могут лайкнуть или не лайкнуть пост на странице с подробным описанием поста. Однако, когда администратор входит в систему из панели администратора django, чтобы одобрить пост и нажать кнопку сохранения, он показывает, что поле 'like' является обязательным. Как я могу решить эту проблему, чтобы администратор мог одобрить пост?
