[FIXED] Call a python function to generate a defalut value in Falsk-SqlAlchemy Model

Issue

I was wondering, is there a problem to call a function in order to generate a default value such as the current time when we want to define a column in our database model? I would be appreciated it if someone helps me with my problem.

Solution

There is no problem, in fact it's often quite handy:

class Item(db.Model):
    created = db.Column(db.DateTime)

    def __init__(self):
        self.created = datetime.utcnow()
