An ObjectId is a 12-byte unique identifier consisting of: - a 4-byte value representing the seconds since the Unix epoch, - a 5-byte random value, - a 3-byte counter, starting with a random value. By default, ``ObjectId()`` creates a new unique identifier. The optional parameter `oid` can be an :class:`ObjectId`, or any 12 :class:`bytes`. For example, the 12 bytes b'foo-bar-quux' do not follow the ObjectId specification but they are acceptable input:: >>> ObjectId(b'foo-bar-quux') ObjectId('666f6f2d6261722d71757578') `oid` can also be a :class:`str` of 24 hex digits:: >>> ObjectId('0123456789ab0123456789ab') ObjectId('0123456789ab0123456789ab') Raises :class:`~bson.errors.InvalidId` if `oid` is not 12 bytes nor 24 hex digits, or :class:`TypeError` if `oid` is not an accepted type. :param oid: a valid ObjectId. .. seealso:: The MongoDB documentation on `ObjectIds `_. .. versionchanged:: 3.8 :class:`~bson.objectid.ObjectId` now implements the `ObjectID specification version 0.2 `_.

This method is useful for doing range queries on a field containing :class:`ObjectId` instances. .. warning:: It is not safe to insert a document containing an ObjectId generated using this method. This method deliberately eliminates the uniqueness guarantee that ObjectIds generally provide. ObjectIds generated with this method should be used exclusively in queries. `generation_time` will be converted to UTC. Naive datetime instances will be treated as though they already contain UTC. An example using this helper to get documents where ``"_id"`` was generated before January 1, 2010 would be: >>> gen_time = datetime.datetime(2010, 1, 1) >>> dummy_id = ObjectId.from_datetime(gen_time) >>> result = collection.find({"_id": {"$lt": dummy_id}}) :param generation_time: :class:`~datetime.datetime` to be used as the generation time for the resulting ObjectId. is)r)r )r5r7r rrr from_datetimezs zObjectId.from_datetimerboolc Cs0|sdSzt|WdSttfyYdSw)zChecks if a `oid` string is valid or not. :param oid: the object id to validate .. versionadded:: 2.3 FT)rr r.)r5r rrris_validszObjectId.is_validrcCs&t}||jkr||_t|_|jS)z1Generate a 5-byte random number once per process.)rgetpid_pidr_ObjectId__random)r5pidrrrr(s  zObjectId._randomcC|jS)z/12-byte binary representation of this ObjectId.r*r2rrrr0szObjectId.binarycCs$t|jddd}tj|tS)a A :class:`datetime.datetime` instance representing the time of generation for this :class:`ObjectId`.
