Mongoengine creation_time attribute in Document

Question

I am trying to add a creation_time attribute to my documents. The following would be an example:

import datetime

class MyModel(mongoengine.Docu         


        

Answer 1

Traditionally, I've set the creation_date default to datetime.now() and then have hidden the field on the admin form so you remove the possibility of a user overwriting the correct value. That requires almost no code.

Overriding the save method as suggested by Willian is also effective since you can programmtically block any updates to the creation_date and update the modfied_date at the same time.
