Document ID and existing unique value in the document about tinydb

[aptly-io]

This might be a recipe for others when a str as doc_id:

class _Document(dict):
    def __init__(self, value: Mapping, doc_id: str):
        super().__init__(value)
        self.doc_id = doc_id

class _Table(Table):
    document_class = _Document
    document_id_class = str
    def _get_next_id(self):
        raise NotImplementedError("doc_id should be self provided")

class _TinyDB(TinyDB):
    table_class = _Table


class Model:

    def __init__(self):
        self._db = _TinyDB("db.json")

There are some issue with table.py though when using _Document ...
