Description

get_default_database.__doc__

Get the database named in the MongoDB connection URI.

        >>> uri = 'mongodb://host/my_database'
        >>> client = MongoClient(uri)
        >>> db = client.get_default_database()
        >>> assert db.name == 'my_database'
        >>> db = client.get_database()
        >>> assert db.name == 'my_database'

        Useful in scripts where you want to choose which database to use
        based only on the URI in a configuration file.

        :Parameters:
          - `default` (optional): the database name to use if no database name
            was provided in the URI.
          - `codec_options` (optional): An instance of
            :class:`~bson.codec_options.CodecOptions`. If ``None`` (the

            used.
          - `read_preference` (optional): The read preference to use. If
            ``None`` (the default) the :attr:`read_preference` of this
            :class:`MongoClient` is used. See :mod:`~pymongo.read_preferences`
            for options.
          - `write_concern` (optional): An instance of
            :class:`~pymongo.write_concern.WriteConcern`. If ``None`` (the

            used.
          - `read_concern` (optional): An instance of
            :class:`~pymongo.read_concern.ReadConcern`. If ``None`` (the
            default) the :attr:`read_concern` of this :class:`MongoClient` is
            used.
