Delete datastore entities by their creation date

[A. Kong]

Hi all,

I have checked the ndb.Model api and there seems to no attribute to hold the creation timestamp of a data store entity.

It is my use case: I want to be able to define a cron job which will sweep  all entities in the datastore. If an entity is created say 24hours ago, it will be deleted. 

I can definitely add a 'creation_time' DateTimeProperty to my data model. However it would be neat if ndb supports this already

Cheers, Tony

Salutations,

This currently does not exist. You can file a Feature Request to add that functionality. In the mean time I would look at this link, specifically:

auto_now_add	Set property to current date/time when entity is created.
auto_now	Set property to current date/time when entity is created and whenever it is updated.
