Is there a way to ignore invalid keys with get_multi?

Question

I would like to have get_multi return None for keys with invalid ids.

class Entity(ndb.Model):
    pass

ids = [0, 1]
rows = ndb.get_multi([Key(Entity, id) for id in ids])

Actual result

BadRequestError('missing key id/name')

Desired result

[None, <Entity with id 1>]

The reason I'm not calling filter on ids is that I want indices in ids to correspond to indices in rows.

Answer 1

Since get_multi is just a helper function, my best solution so far is to copy the code and only run the query if id > 0.

ids = [0, 1]
futures = [Key(Entity, id).get_async() if id > 0 else None for id in ids]
rows = [future.get_result() if future else None for future in futures]
