Description

help(UpdateOne.__init__)

Represents an update_one operation.

For use with :meth:`~pymongo.asynchronous.collection.AsyncCollection.bulk_write`, :meth:`~pymongo.collection.Collection.bulk_write`,
:meth:`~pymongo.asynchronous.mongo_client.AsyncMongoClient.bulk_write` and :meth:`~pymongo.mongo_client.MongoClient.bulk_write`.

:param filter: A query that matches the document to update.
:param update: The modifications to apply.
:param upsert: If ``True``, perform an insert if no documents
    match the filter.
:param collation: An instance of
    :class:`~pymongo.collation.Collation`.
:param array_filters: A list of filters specifying which
    array elements an update should apply.
:param hint: An index to use to support the query
    predicate specified either by its string name, or in the same

    ``[('field', ASCENDING)]``). This option is only supported on
    MongoDB 4.2 and above.
:param namespace: The namespace in which to update a document.
