is there an auto update option for DateTimeField in peewee like TimeStamp in MySQL?

Question

I would like a timestamp field updating each time the record is modified like in MySQL.

DateTimeField(default=datetime.datetime.now()) will only set it the first time it is created...

Any have a simple solution? Is the only solution is to manually set the Column options in MySQL db?

You can override the save method on your model class.

class Something(Model):
    created = DateTimeField(default=datetime.datetime.now)
    modified = DateTimeField

    def save(self, *args, **kwargs):
        self.modified = datetime.datetime.now()
        return super(Something, self).save(*args, **kwargs)
