Is it possible to link fields together in mongoengine models?

Question

Django

Is it possible to bind the fields of mongoengine models so that when a field in one document changes, the value of the associated field in another document or even in several documents changes automatically ??? In terms of functionality, I could find a similar one - ReferenceField , only it refers to the whole document, and not to a specific field, and as I understand it, it works very slowly.

Answer 1

well, as an option in other documents, refer to the ID of the main document and not write all the data in full there. when getting data in other documents, just make an additional request from the main reference document.
