SqlAlchemy won't accept datetime.datetime.now value in a DateTime column

Question

I should first mention that I\'m using SqlAlchemy through Flask-SqlAlchemy. I don\'t believe this affects the issue but if it does, please let me know.

Here is the relev

Answer 1

Set the import out the class.

from datetime import datetime

last_updated = db.Column(db.DateTime, default=datetime.now())

or

import datetime

last_updated = db.Column(db.DateTime, default=datetime.datetime.now())

I did this

Answer 2

Look at your line:

last_updated = db.Column(db.DateTime, default=datetime.datetime.now)

There is no datetime.datetime.now attribute in python. However, there is a datetime.datetime.now() function in python. You were just missing a pair of parentheses.

Answer 3

last_updated = db.Column(db.DateTime, default=db.func.current_timestamp())

I think this will work

Answer 4

Try to use datetime.datetime.utcnow(). This works for me.
