I’m trying to find a way to create a document key [not primary key, but still unique] that is user friendly (like 6 digits/letters long or something). I’ve looked at using a SequenceField [mongoengine], but I’ve also read about its drawbacks and the preference for ObjectIDs instead.
Basically, I’m trying to achieve something like this MongoDB blogpost, where I can auto_version documents, but ideally also have a user friendly key-field that allows me to pull up all versions of the document at once.
I hope that makes sense… I’m new to MongoDB.
Thx!
>Solution :
You can self generate a uuid to be used as a unique identifier (e.g. doc_id) for versioning, and keep ObjectID as a _id.
Example packages
Nodejs – https://www.npmjs.com/package/uuid
Golang – https://github.com/google/uuid
Python – https://docs.python.org/3/library/uuid.html
