MODX / MIGX Добавление авторов для статей

Добрый день. Есть сайт журнала. Установлен MODX 2.2.7, Статьи 1.6.0, MIDX последние. Для каждого выпуска журнала в статьях создается контейнер, в который добавляются статьи. Я хочу сделать базу данных авторов, которые будут добавляться в разные статьи журнала. Каждый автор должен иметь причастность к университету (соответственно, должен быть готовый список их). Кроме того, для каждого автора должны быть поля Фамилия, Инициалы, E-mail, Университет, ORCID. Теперь я попытался реализовать это через midxdb следующим образом:

База данных была создана. При отображении ТВ есть таблица, в которую я могу добавлять авторов. Я не знаю, как реализовать добавление каждого отдельного автора из таблицы в конкретную статью из контейнера. Кроме того, таблица не отображается вообще с «check_resid»: 1. В БД после добавления автора его resource_id — 0.

Как я могу решить эту проблему? Заранее спасибо!
