How to create cursor with NDB map
According to the documentation , the function map
supports all query keywords. However, I cannot get the values cursor
and has_more
using the map. How do you do it? If I use fetch
to create result
, cursor
and has_more
, I can't use map
it anymore as it doesn't work on simple lists.

You cannot get the cursor from the map () - the only way to get the cursor is by using a QueryIterator or by calling fetch_page () (which uses a QueryIterator internally). The has_more flag is only available with fetch_page ().
If you have a simple list, use Python's built-in map () function:
map(<function>, <list-of-entries>)
But maybe you could tell us more about what you are trying to do?
