У меня есть таблица компаний, таблица адресов и таблица businessadresses для нормализации отношения многих к многим. Loopback работает отлично, чтобы добавить компанию, добавить адрес в компанию, и я даже могу запросить с помощью API explorer адрес, связанный с компанией, используя метод POST/Companies/{id}/addresses/{fk}.Имеет много сквозных отношений, count всегда возвращает 0
Однако, когда я пытаюсь получить все адреса, связанные с компанией (GET/Companies/{id}/addresses), я возвращаю пустой массив. Кроме того, когда я выполняю подсчет количества адресов конкретной компании (GET/Companies/{id}/addresses/count), я всегда получаю 0.
Уверен, что мне не хватает чего-то действительно крошечного. Мой источник данных - postgresql.
