[1.3.X] Fixed #16293: Document a way to return dicts with column names from a...

    # Your code here...

    transaction.commit_unless_managed(using='my_db_alias')

By default, the Python DB API will return results without their field

names, which means you end up with a ``list`` of values, rather than a

``dict``. At a small performance cost, you can return results as a

``dict`` by using something like this::

    def dictfetchall(cursor):

        "Returns all rows from a cursor as a dict"

        desc = cursor.description

        return [

            dict(zip([col[0] for col in desc], row))

            for row in cursor.fetchall()

        ]

Here is an example of the difference between the two::

    >>> cursor.execute("SELECT id, parent_id from test LIMIT 2");

    >>> cursor.fetchall()

    ((54360982L, None), (54360880L, None))

    >>> cursor.execute("SELECT id, parent_id from test LIMIT 2");

    >>> dictfetchall(cursor)

    [{'parent_id': None, 'id': 54360982L}, {'parent_id': None, 'id': 54360880L}]
