Functions vs. return value

import datetime

pub_date = models.DateTimeField(default=dateime.datetime.now)

——

here, datetime.datetime.now is the function

this will be repeatedly called whenever the instance is created.

But, if datetime.datetime.now() is used

it would be called once when the model is first loaded.

So, please use the function here rather than return value.
