ahvn.utils.mdb.types module

MongoDB type definitions and conversion utilities for UKF models.

class ahvn.utils.mdb.types.BaseMongoType(**kwargs)

class ahvn.utils.mdb.types.MongoTagsType(**kwargs)

基类：BaseMongoType

Tags type for MongoDB (stored as array of {slot, value} subdocuments).

UKF tags are stored as strings like "[slot:value]". MongoDB stores them as subdocuments: [{"slot": "...", "value": "..."}, ...]
