`id` as a unique field alongside `_id` #2819

Closed iebb closed 3 months ago

iebb commented 5 months ago

Migrating from Djongo here, and my current data involves - _id: the automatic ObjectId field id: Django-style integer field with a unique index.

As I want to maintain compatibility between Djongo model and MongoEngine, and since MongoEngine relies heavily on the 'id' field, what's the current best practice for MongoEngine to maintain both?

As you pointed out, id is kind of an alias for _id in MongoEngine and I don't have a workaround (and don't think it's such a common scenario to develop one)

One thing you can consider is to use your django style integer as id

class YourDoc(Document):
    id = IntegerField(primary_key=True)
    ...
