Удалить условие соответствия документа в множественной коллекции MongoDB

0 голосов
/ 26 мая 2020

У меня есть архитектура базы данных в MongoDB, как показано ниже:

enter image description here

Я хочу, чтобы при удалении одного документа в коллекции company_info он должен удалить весь документ которые имеют тот же com_id с удаленным документом в коллекции company_info.

Например, когда я удаляю документ с coimid = DHBK в коллекции company_info, mon go оболочка должна удалить весь документ в коллекции отношений (users , company_user_role, ...) который имеет comid = DHBK

Я не знаю оболочки mon go для выполнения этого действия.

Вот пример моей базы данных:

На данный момент Mon go не поддерживает операцию каскадного удаления. Пн go просто делает то, что ему сказали. Каскадное удаление не является концепцией MongoDB, это скорее концепция SQL.

Итак, на данный момент вы можете вручную удалить соответствующую запись в каждой коллекции. Вы можете использовать следующую команду для удаления документа: 

db.Users.remove({coimid: 'DHBK'})
db.Company_user_role.remove({coimid: 'DHBK'})
... // And so on...

Есть другой способ, но это долгий путь. Что вы можете сделать, так это изменить свою схему. Вместо того, чтобы создавать разные коллекции, вы можете собрать все в одну коллекцию. Но я бы порекомендовал вам сделать это, только если ваши коллекции подключены и они часто обновляются.
