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

My preferred solution is to use the @property decorator to return the creation datetime as extracted from the ObjectId:

@property
def creation_stamp(self):
    return self.id.generation_time
